EPF6024AQI208-3N Overview

The Altera EPF6024AQI208-3N is a member of the FLEX 6000 family of Field Programmable Gate Arrays, delivering 24,000 gates, 1,960 logic elements (cells), and a maximum internal operating frequency of 142.86 MHz in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. Manufactured on a 0.42 µm CMOS process with a 3.3 V core supply, the device combines a register-rich, look-up-table (LUT) based OptiFLEX architecture with 171 user I/O pins, making it suited for high-volume gate array replacement and rapid prototyping flows.

A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows engineers to implement arbitrary digital logic via a configurable array of logic blocks, routing channels, and I/O cells. Within the broader taxonomy, the FLEX 6000 sits as a low-cost, register-rich mid-density FPGA, positioned between simple CPLDs and higher-density SRAM-based FPGAs such as the FLEX 10K and APEX families. The FLEX 6000 family was specifically architected as an ideal low-cost programmable alternative to high-volume gate array applications, enabling fast design changes during prototyping and design testing.

Key features include the OptiFLEX architecture for high utilization, multiVolt I/O support for interfacing with 2.5 V, 3.3 V, and 5 V buses, in-system programmability through a dedicated configuration interface, and JTAG boundary-scan test support per IEEE 1149.1. The "3N" speed grade designation places this part in a specific performance bin optimized for typical commercial industrial temperature ranges. With 1,960 logic elements and abundant user I/O, the EPF6024AQI208-3N delivers substantial logic capacity for glue logic, bus bridging, and parallel DSP pre/post-processing tasks.

From an architectural perspective, the FLEX 6000 family employs continuous, segmented routing interconnect combined with dedicated carry chains and cascade chains that accelerate arithmetic and wide datapath operations. The 0.42 µm four-metal-layer CMOS process delivers a balance of die density, static power, and 3.3 V tolerance that was industry-leading at product introduction.

Typical applications include industrial control glue logic, telecommunications interface bridging, prototyping of ASIC designs, parallel peripheral controllers, and embedded system bus arbiters. The 208-pin PQFP package and 171 user I/O pins enable direct interfacing with wide parallel buses such as PCI, ISA, and external memory buses.

When designing with this device, pay close attention to configuration mode selection and the configuration device interface, since the FLEX 6000 family supports both passive serial and passive parallel configuration schemes with EPC configuration memories. Designers should also verify supply decoupling on every VCCINT and VCCIO pin per the FLEX 6000 Device Family datasheet recommendations.

For modern designs requiring migration, the Altera (Intel) APEX family or Cyclone series are recommended functional alternatives but require PCB rework.
EPF6024AQI208-3N vs EPF6024AQC208-3N - which is the better replacement?
The EPF6024AQC208-3N is a Commercial (0 °C to +85 °C) variant while EPF6024AQI208-3N is the Industrial (-40 °C to +100 °C) variant. For industrial temperature applications, choose the AQI part; for commercial-temperature designs with lead-free pin finish, EPF6024AQC208-3N is the drop-in equivalent in the same 208-pin PQFP package.
When should I choose EPF6024AQI208-3N over the -3 or -1 speed grade?
Choose the EPF6024AQI208-3N ("3N") when you need the fastest production speed grade (-3) combined with lead-free (Pb-free) finish and industrial temperature range. Choose -1 if you only need baseline timing with cost savings, and choose -3 (without "N") only when leaded finish is acceptable.
Is EPF6024AQI208-3N suitable for new industrial designs in 2026?
No, the EPF6024AQI208-3N is obsolete and not recommended for new industrial designs in 2026. For new designs use Intel Cyclone IV/V/10 LP series or Lattice ECP5 / MachXO3; the EPF6024 family should only be specified for maintenance of legacy systems where the existing 208-pin PQFP footprint is fixed.
What configuration memory should I use with EPF6024AQI208-3N?
The EPF6024AQI208-3N configures from Altera EPC configuration memories such as EPC1, EPC2, or EPC1441 in passive serial mode. Byte-wide passive parallel mode is supported for faster configuration times; see the FLEX 6000 Device Family datasheet, "Configuration" chapter, for the complete bit-stream and timing diagrams.
What is the input/output voltage compatibility of EPF6024AQI208-3N?
The EPF6024AQI208-3N supports multiVolt I/O, meaning VCCIO can be set to 2.5 V, 3.3 V, or 5 V while VCCINT remains at 3.3 V, allowing direct interface to mixed-voltage buses. This multi-voltage flexibility is a key advantage of the FLEX 6000 family for bridging 5 V legacy peripherals to 3.3 V processors.

Selection Guide

Choose EPF6024AQI208-3N when you need the fastest speed grade (-3) of the FLEX 6000 family in a 208-pin PQFP, with industrial temperature range (-40 to +100 °C) and lead-free Pb-free finish. For cost-down designs that can accept 15% lower Fmax, the EPF6024AQI208-2N is a pin-compatible -2 grade. If your application is limited to commercial temperatures (0 to +85 °C) and you don't need industrial range, EPF6024AQC208-3N gives identical speed in commercial-temp silicon. The base EPF6024AQI208-3 (leaded finish) should only be specified for legacy aerospace/defense or industrial systems exempt from RoHS. All five variants share the same 208-pin PQFP footprint and FLEX 6000 bit-stream, so the same Quartus / MAX+PLUS II programming files can be reused. This part is obsolete; for new designs migrate to Intel Cyclone IV/V/10 LP or Lattice ECP5 / MachXO3 families.

Key Differentiators

  • Fastest FLEX 6000 speed grade in industrial temperature range (vs EPF6024AQI208-2N)
  • Industrial -40 to +100C operating range vs commercial 0-85C (vs EPF6024AQC208-3N)
  • Lead-free Pb-free finish (N suffix) for RoHS compliance (vs EPF6024AQI208-3)

Design Notes

Decouple every VCCINT and VCCIO pin with 0.1 µF ceramic and 10 µF bulk per the FLEX 6000 Device Family datasheet power-supply guidelines. The 0.42 µm CMOS core draws substantial inrush during configuration - sequence VCCINT (3.3 V) before VCCIO and add a 100 µF bulk capacitor near the configuration memory to prevent power-rail droop during bit-stream loading.

The 208-pin PQFP has 0.5 mm lead pitch and gull-wing leads - allocate at least 1 oz copper pours under the device for thermal spreading and ground return. Use a 4-layer PCB with dedicated VCC and GND planes; the FLEX 6000 family datasheet recommends matched impedance traces of 50 Ω single-ended for clock inputs.

Configure global clock buffers (CLK0/CLK1) with dedicated low-skew routing and place clock-input pins at package corners closest to the clock source. For high-speed designs exceeding 100 MHz, terminate clock traces with 33 Ω series resistors at the driver to dampen reflections on the relatively long PQFP bond-wire-to-pin path.

Do not confuse 'I' (Industrial temperature grade) with 'C' (Commercial) in the FLEX 6000 ordering code - the EPF6024AQI vs EPF6024AQC variants are NOT thermal drop-in equivalents. Also, the 'N' suffix indicates Pb-free finish; mixing leaded and lead-free PQFPs on the same board can cause assembly defects and tombstoning during reflow.
