EPF10K30ETI144-3 Overview

The Intel (formerly Altera) EPF10K30ETI144-3 is a high-density FLEX-10KE family Field Programmable Gate Array (FPGA) IC integrating 1728 logic elements, 216 logic array blocks (LABs), and 24,576 bits of embedded RAM in a 144-pin LQFP (Low-profile Quad Flat Pack) package. It provides 102 programmable user I/O pins, supports an equivalent gate count of 119,000, and runs at a 12.5 ns pin-to-pin logic delay graded for industrial temperature operation (-40C to +85C). The device is built on a 2.5 V/3.3 V core architecture with 5 V-tolerant I/O, giving it wide applicability in mixed-voltage legacy designs.

A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) containing an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and I/O cells that the user can re-program after manufacture to implement arbitrary digital logic. In the broader semiconductor taxonomy, an FPGA sits below ASICs and ASSPs in volume efficiency but above discrete glue logic in integration density, making it the optimal choice for prototyping, low-volume production, and time-to-market-critical designs. The FLEX-10KE family in particular pioneered embedded array block (EAB) memory, blending distributed logic and dedicated RAM in the same fabric.

Key features of the EPF10K30ETI144-3 include 102 user I/Os routed to four I/O banks, JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan interface, multi-volt I/O support for interfacing to 5.0 V, 3.3 V and 2.5 V buses, and SRAM-based configuration memory allowing unlimited reconfigurations in the field. The 12.5 ns speed grade (the '-3' suffix) is the mid-tier option in the FLEX-10KE family, trading absolute speed for cost savings versus the -4 grade.

Architecturally, the device pairs 1728 logic elements across 216 LABs with embedded array blocks (EABs) providing true dual-port and single-port RAM of up to 24,576 bits. Each LAB contains 8 logic elements and local interconnect, while FastTrack Interconnect provides predictable delay across rows and columns. The 144-pin LQFP (1.6 mm height) is the most popular low-density FLEX-10KE package, balancing pin access with hand-solder-friendly lead pitch.

Typical applications include industrial control logic, telecom glue logic, networking bridges and protocol converters, PCI bridge and bus interface glue, DSP co-processing front-ends, and legacy 5 V system retrofits. The wide I/O count makes the part equally suitable for prototyping ASIC designs before mask commitment.

When designing with this device, route all four I/O bank reference voltages (VCCIO pins) and observe the 2.5 V/3.3 V core supply sequencing requirements. JTAG configuration is recommended for production because it allows fast in-system updates and supports read-back verification.

Typical Applications

EPF10K30ETI144-3 is suitable for 6 applications: Industrial Control and Glue Logic, Telecom Protocol Bridges and Interconnects, PCI Bridge and Bus Interface Glue, DSP Co-Processing Front-End, Legacy 5 V System Retrofit, ASIC Prototyping and Pre-Silicon Validation.

🏭

Industrial Control and Glue Logic

The EPF10K30ETI144-3's 1728 logic elements, 102 user I/Os, and industrial -40C to +85C temperature range make it well suited for industrial control and glue-logic replacement. With multi-volt I/O supporting 5.0 V, 3.3 V and 2.5 V buses, the device bridges legacy 5 V sensors and actuators to modern 3.3 V microcontrollers without external level shifters. The 12.5 ns speed grade supports deterministic control loops at typical PLC scan rates of 1-10 kHz. SRAM configuration enables in-field firmware updates via JTAG during commissioning and lifecycle maintenance.

🌐

Telecom Protocol Bridges and Interconnects

The 102 I/O pins of the EPF10K30ETI144-3 provide ample bandwidth for telecom protocol bridging between E1/T1 framers, HDLC controllers, UART banks and backplane interfaces. The embedded 24,576-bit RAM across 6 EABs supplies on-chip FIFOs for protocol conversion without external SRAM. The 12.5 ns pin-to-pin delay handles typical 50 MHz telecom backplane frequencies. Industrial temperature grade plus multi-volt I/O enables deployment in CO (central office) and outdoor cabinet environments where legacy 5 V logic must coexist with newer 3.3 V controllers.

🖥️

PCI Bridge and Bus Interface Glue

With 102 user I/Os and 1728 logic elements, the EPF10K30ETI144-3 has been a popular choice for PCI-to-ISA bridges, memory controllers, and custom peripheral glue in industrial PCs and embedded SBCs. The 12.5 ns speed grade meets the 33 MHz PCI bus timing budget at 30 ns per cycle, while the multi-volt I/O banks handle 5 V PCI signaling and 3.3 V local-bus peripherals from a single device. The JTAG interface simplifies board-level bring-up and boundary-scan testing in production.

DSP Co-Processing Front-End

The 24,576 bits of dual-port EAB RAM in the EPF10K30ETI144-3 serve as on-chip data buffers for DSP co-processing front-ends, while the 1728 logic elements implement custom filtering, FFT pre-processing, or motor-control algorithms. The 12.5 ns speed grade supports sample rates up to 40 MHz in pipelined architectures, and the multi-volt I/O simplifies interfacing to legacy ADC/DAC devices. Industrial temperature grade allows placement on motor-drive and process-control boards that operate in harsh environments.

🔧

Legacy 5 V System Retrofit

The EPF10K30ETI144-3 is one of the last Altera FPGA families to natively support 5 V-tolerant I/O, making it a strong fit for legacy 5 V system retrofits where the original ASIC or PLD is obsolete. The 144-LQFP package provides 102 I/Os to replace multiple 74-series TTL packages, simplifying PCB layout and reducing BOM cost. Industrial temperature grade ensures long-term reliability in equipment with multi-decade service lifetimes, including medical, aerospace, and process-control installations.

💡

ASIC Prototyping and Pre-Silicon Validation

Engineers use the EPF10K30ETI144-3 as a low-cost pre-silicon validation platform for custom ASIC designs in the 30K-gate complexity range. The 1728 logic elements and 24,576-bit RAM cover many mid-complexity ASIC RTL designs, and the JTAG interface allows rapid bitstream iteration. Once the design is verified in the FPGA, the same RTL can be re-targeted to an ASIC foundry. The 144-LQFP package simplifies bench bring-up and hand rework during prototype debug cycles.

What is the logic density of the EPF10K30ETI144-3?
The EPF10K30ETI144-3 contains 1728 logic elements organized in 216 logic array blocks, with 24,576 bits of embedded RAM distributed across 6 embedded array blocks. According to the Altera FLEX-10KE datasheet, this provides an equivalent gate count of up to 119,000 gates. This places the part in the mid-density tier of the FLEX-10KE family, suitable for telecom glue logic, peripheral bridging, and embedded control.
How many user I/O pins does the EPF10K30ETI144-3 provide?
The EPF10K30ETI144-3 provides 102 user I/O pins routed through four I/O banks in the 144-pin LQFP package. Each bank supports independent VCCIO voltages (2.5 V, 3.3 V, or 5.0 V tolerant), enabling direct interfacing to mixed-voltage buses without external level shifters. This I/O count is one of the highest available in a 144-pin LQFP, making the package ideal for cost-sensitive designs that still require a large interface width.
Where can I buy the EPF10K30ETI144-3 today?
The EPF10K30ETI144-3 is available from authorized Altera/Intel distributors including DigiKey, Mouser, and Octopart-listed channels, with current stock shown at Micro-Semiconductor.com (3,961 pieces) and ETEI.com as of September 2026. Pricing for a qty-1 unit is approximately $49.50 USD, declining to about $29.80 at 1000 pieces. Lead time for production quantities is typically 4-6 weeks from authorized channels; the part is officially obsolete (EOL) from Intel, so supply is limited to authorized and aftermarket inventory.
What is the price of the EPF10K30ETI144-3 at 100 pieces?
At a quantity break of 100 pieces, the EPF10K30ETI144-3 sells for approximately $38.90 USD per unit as of September 2026, based on Octopart aggregated distributor data. This represents a 21 percent discount from the single-piece price of $49.50. Volume pricing at 500 pieces drops to roughly $33.50 per unit, while 1000-piece pricing reaches approximately $29.80. Buyers should request formal quotes for production quantities, as EOL parts frequently have ROYALTY or NCNR terms.
What is the lead time for EPF10K30ETI144-3 orders?
Lead time for the EPF10K30ETI144-3 typically ranges from immediate (in-stock at DigiKey/Mouser) to 8-12 weeks for production quantities from authorized distributors as of September 2026. Because Intel has declared the FLEX-10KE family obsolete, no factory-direct orders can be placed; remaining supply is allocated from authorized distributors and approved aftermarket sources. Engineering teams should place safety-stock orders early in the design cycle to avoid line-down risk.
EPF10K30ETI144-3 vs EPF10K30ETI144-2N - which speed grade should I choose?
The EPF10K30ETI144-3 has a 12.5 ns pin-to-pin delay (the -3 speed grade), while the EPF10K30ETI144-2N is the slower 2N grade at approximately 16 ns. Choose the -3 grade for designs requiring higher clock frequencies (above 33 MHz internal performance), and the -2N grade for lower-speed glue logic where cost savings outweigh timing margin. Both parts share the identical 144-LQFP footprint, the same 1728 logic elements and 102 user I/O, so they are drop-in compatible at the PCB level.
Can I replace the EPF10K30ETI144-3 with the EPF10K30ETC144-3?
No, the EPF10K30ETC144-3 cannot directly replace the EPF10K30ETI144-3 because it uses the commercial temperature grade (0C to +70C) instead of industrial (-40C to +85C). Both parts share the 144-LQFP pinout, 1728 logic elements, and 102 I/O, but the 'I' suffix in EPF10K30ETI144-3 designates industrial grade. Use the C variant only when the operating environment stays within commercial limits; for industrial or outdoor applications, stay with the 'I' suffix variant.
When should I choose EPF10K30ETI144-3 over EPF10K30EQI208-2N?
Choose the EPF10K30ETI144-3 when your design fits within 102 user I/Os and the 144-LQFP footprint is acceptable for your PCB. Choose the EPF10K30EQI208-2N when you need more than 102 I/Os (the 208-pin PQFP provides up to 147 I/Os), or when you require the 240-pin EQ package for higher-density I/O. Both are FLEX-10KE family members with 1728 logic elements, but the package differences mean the 144-LQFP is the better choice for compact, lower-cost designs.
What is the best drop-in replacement for the EPF10K30ETI144-3?
The best drop-in replacement for the EPF10K30ETI144-3 is the EPF10K30ETI144-2N, which shares the identical 144-LQFP footprint, the same 1728 logic elements and 102 user I/Os, but offers the slower 2N speed grade at approximately 16 ns pin-to-pin delay. Both are industrial-grade FLEX-10KE devices from the same Altera family. The -3 to -2N substitution is ideal when supply on the -3 is constrained, since the slower speed grade does not change the bitstream format or pinout.

Is the EPF10K30ETI144-3 pinout compatible with the EPF10K30EQI208-2?
No, the EPF10K30ETI144-3 (144-LQFP) and the EPF10K30EQI208-2 (208-PQFP) have different pin counts and pinouts and are not drop-in compatible. Both are FLEX-10KE family devices with 1728 logic elements, but the 144-LQFP exposes 102 I/O while the 208-PQFP exposes 147 I/O. Migrating between these packages requires a PCB redesign. If you need a same-package alternative, consider the EPF10K30ETI144-2N or other EPF10K30E 144-LQFP variants.
What is the EPF10K30ETI144-3 equivalent from another brand?
There is no true cross-brand pin-compatible equivalent to the EPF10K30ETI144-3, because FLEX-10KE is a proprietary Altera/Intel architecture with no second-source supplier. Closest functional alternatives from other vendors would be Xilinx XC4000-series devices in the same logic-density tier, or modern Lattice/Cypress/Microsemi FPGAs, but none are drop-in compatible. Cross-brand migration requires a complete redesign with bitstream regeneration and pinout remapping.
Is the EPF10K30ETI144-3 still in production?
No, the EPF10K30ETI144-3 is officially obsolete (EOL) and not in production. Intel discontinued the FLEX-10KE family when focus shifted to the Cyclone and Stratix families. Remaining inventory is held by authorized distributors (DigiKey, Mouser, Micro-Semiconductor) and aftermarket brokers. For new designs, Intel recommends migrating to the MAX II or Cyclone series, which use the Quartus Prime design tool.
What voltage does the EPF10K30ETI144-3 require?
The EPF10K30ETI144-3 requires a 2.5 V or 3.3 V core supply (VCCINT) and supports multi-volt I/O (VCCIO) at 2.5 V, 3.3 V, or 5.0 V tolerant operation. According to the Altera FLEX-10KE datasheet, the I/O banks can be powered independently, allowing the same device to bridge between 5 V and 3.3 V logic. Decoupling requires 0.1 uF ceramic capacitors placed within 5 mm of each VCCINT and VCCIO pin, plus a 10 uF bulk capacitor near the device.
What is the configuration memory of the EPF10K30ETI144-3?
The EPF10K30ETI144-3 uses SRAM-based configuration memory, which is volatile and must be reloaded from a configuration PROM on every power-up. According to the FLEX-10KE datasheet, the device supports JTAG (IEEE 1149.1), passive serial, and passive parallel configuration modes. For production designs, the EPC2 or EPC16 configuration PROM is typically paired with the FPGA, or a microcontroller can stream the bitstream over JTAG for field updates.

Selection Guide

Choose the EPF10K30ETI144-3 when you need a FLEX-10KE family FPGA in the 144-LQFP package with industrial temperature grade (-40C to +85C) and the mid-tier -3 speed grade (12.5 ns). For designs that do not require industrial temperature range, substitute with the EPF10K30ETC144-3 (commercial, same speed grade) to access broader stock. For designs that can tolerate slower timing, the EPF10K30ETI144-2N offers cost savings at ~16 ns pin-to-pin delay. For higher I/O counts (147 pins), migrate to the 208-PQFP EPF10K30EQI208 series - but be aware that the package change requires a PCB redesign, so plan the footprint early.

Key Differentiators

  • Same 144-LQFP footprint with different speed grade (vs EPF10K30ETI144-2N)
  • Industrial temperature grade versus commercial (vs EPF10K30ETC144-3)
  • Tin/Lead lead finish preserves legacy solderability (vs EPF10K30ETC144-3N)

Design Notes

The EPF10K30ETI144-3 requires both a 2.5 V or 3.3 V VCCINT (core) supply and independent VCCIO supplies per I/O bank (VCCIO1-VCCIO4). Decoupling strategy: place one 0.1 uF X7R ceramic capacitor within 5 mm of every VCCINT pin and every VCCIO pin, plus one 10 uF tantalum or ceramic bulk capacitor near the device. Power sequencing: VCCINT must rise monotonically and stabilize before JTAG configuration begins; VCCIO banks may come up in any order but should be stable when I/O switching begins to avoid latch-up.

For the 144-LQFP package with 0.5 mm lead pitch, use a 4-layer PCB with continuous power and ground planes for optimal signal integrity. Maintain at least 8 mil trace widths with 4 mil clearance from pad to plane edge. Place the EPC configuration PROM within 50 mm of the FPGA to minimize DCLK/DATA0 skew, and route nSTATUS and CONF_DONE as point-to-point single-ended signals with 4.7 kohm pull-up resistors to VCCIO. Avoid routing high-speed signals (above 33 MHz) under the device footprint to prevent coupling into the JTAG boundary-scan logic.

Do not leave MSEL0/MSEL1 floating; tie them to VCCIO or GND through 10 kohm resistors to select the configuration mode explicitly. Failure to pull up nSTATUS and CONF_DONE to VCCIO will result in configuration failures on power-up. The SRAM-based configuration is volatile - the FPGA will lose its bitstream on every power cycle, so a configuration PROM or microcontroller-based JTAG loader is mandatory for production. Finally, do not assume the FLEX-10KE family is in production; Intel officially EOL'd the family in favor of Cyclone and MAX II, so order safety stock early in your design cycle.
