EPC2-TI32N Overview
A configuration PROM is a non-volatile memory device that stores the FPGA bitstream and loads it into the SRAM configuration cells of an SRAM-based FPGA on every power-up. Without a configuration PROM, an SRAM-based LUT FPGA forgets its logic configuration the instant power is removed, because SRAM cells are volatile. The EPC2 family therefore plays a critical role in the FPGA hardware hierarchy, bridging the permanent storage domain (Flash/EEPROM cells inside the EPC2) and the volatile logic domain (FPGA LUT and routing SRAM). Hypernymically, this places the part in the chain: configuration PROM -> serial configuration memory -> non-volatile memory -> memory IC -> integrated circuit.
Key features include 1.6 Mb of Flash memory organized as 1,695,680 x 1, an IEEE 1532-compliant JTAG interface for in-system programming, a multi-voltage I/O architecture that interfaces directly to 1.8 V, 2.5 V, 3.3 V and 5 V FPGAs, and a dedicated serial configuration clock output. The 32-TQFP (7x7) package provides a compact 0.8 mm terminal pitch suitable for space-constrained designs and supports an industrial operating temperature range of -40 C to +85 C.
Typical applications include storing the configuration bitstream of Altera Cyclone, Cyclone II, Stratix, Stratix II, APEX and other SRAM-based LUT FPGAs in industrial controllers, factory automation equipment, telecommunications line cards, test and measurement instruments, and any system that requires a single-chip, in-system-reprogrammable boot source for an SRAM FPGA. The JTAG ISP capability allows field firmware upgrades without removing the PROM from the board.
When designing with this part, note that the EPC2 family is now in the long-term support phase. Designers of new products should evaluate Intel MAX series configuration devices or the latest MAX V/MAX 10 CPLDs with on-chip Flash configuration memory. For legacy board revs, the EPC2-TI32N remains a valid drop-in choice because it shares the same TQFP-32 footprint as the EPC1 and EPC1441 families.

Typical Applications
EPC2-TI32N is suitable for 6 applications: FPGA Configuration Memory for Cyclone Series, Industrial Control and Factory Automation, Telecommunications Line Cards, Test and Measurement Instrumentation, Military and Aerospace Legacy Systems, Medical Imaging and Diagnostic Devices.
FPGA Configuration Memory for Cyclone Series
The EPC2-TI32N stores the 1.6 Mb-class bitstream of Altera Cyclone and Cyclone II SRAM-based LUT FPGAs at board power-up. With 1,695,680 x 1 bit Flash organization and a dedicated DCLK output, it streams configuration data into the FPGA's passive serial interface reliably, eliminating the need for a parallel Flash plus controller. The 32-TQFP (7x7) footprint keeps the boot source within 49 mm^2 of board area, ideal for cost-sensitive industrial boards. JTAG ISP allows field firmware upgrades without de-soldering the PROM.
Recommended
Industrial Control and Factory Automation
The EPC2-TI32N's industrial -40 C to +85 C operating range and 5 V/3.3 V dual-voltage I/O make it a robust configuration source for FPGA-based PLCs, motor controllers, and machine vision subsystems in factory automation. The JTAG IEEE 1532 interface lets field engineers re-flash the boot bitstream through a JTAG header when production-line firmware revisions ship, avoiding board swap. The 1.6 Mb density covers most Cyclone-class designs used in distributed I/O and conveyor control.
Recommended
Telecommunications Line Cards
Telecom line cards often use SRAM-based LUT FPGAs for protocol bridging, SERDES aggregation, and packet classification. The EPC2-TI32N supplies a deterministic 1.6 Mb boot image for these FPGAs across the -40 C to +85 C industrial temperature range required by NEBS-style telecom environments. The 5 V-tolerant VCCIO rail interfaces directly to legacy 5 V FPGAs while the 3.3 V VCCINT rail can run from a standard telecom intermediate bus, simplifying power tree design.
Recommended
Test and Measurement Instrumentation
Bench-top and rack-mount test equipment frequently use SRAM FPGAs for high-speed DSP and waveform synthesis, and these instruments benefit from a field-reprogrammable boot PROM. The EPC2-TI32N's JTAG ISP enables calibration engineers to push new FPGA firmware through a JTAG probe during instrument validation, then lock the final image with JTAG security bits. The 32-TQFP package is friendly to mixed-signal PCB layouts where analog isolation is critical.
Recommended
Military and Aerospace Legacy Systems
Long-lifecycle defense and avionics platforms continue to use Altera Cyclone-class FPGAs and the EPC2-TI32N as the configuration source because of mature supply chain and verified reliability data. The device's industrial -40 C to +85 C range, combined with the dual-voltage I/O, suits avionics LRUs (Line Replaceable Units) that need a stable boot image over decades of service. Designers should note Intel's NRNR designation and plan last-time-buys accordingly.
Recommended
Medical Imaging and Diagnostic Devices
Medical imaging carts, ultrasound front-ends, and patient monitors employ SRAM-based LUT FPGAs for high-speed signal conditioning. The EPC2-TI32N provides a deterministic, JTAG-reprogrammable boot image that supports field firmware updates required for FDA change-control workflows. The 5 V-tolerant I/O simplifies interface to legacy imaging analog front-ends that run from 5 V rails, and the industrial temperature grade accommodates the thermal envelope of cart-mounted equipment.

Key Differentiators
- In-system programmable via IEEE 1532 JTAG (vs EPC1441TI32N)
- Industrial -40 C to +85 C temperature grade (vs EPC2-TI32)
- Dual-voltage I/O supports 1.8 V to 5 V FPGAs (vs EPC1LC20)
Design Notes
The EPC2-TI32N requires two separate supply rails: VCCINT (3.0 V to 3.6 V) and VCCIO (4.5 V to 5.5 V). Per the Altera Configuration Devices datasheet, both rails must be present before configuration begins; if VCCINT rises before VCCIO, the device enters a high-impedance state and the FPGA will not receive its bitstream. Decouple each VCC pin with a 0.1 uF ceramic capacitor placed within 5 mm of the lead, and add a bulk 10 uF tantalum or ceramic near the package.
The EPC2-TI32N is in NRNR lifecycle. New designs should not select this part without consulting Intel FPGA support for the most recent configuration device roadmap. Common pitfalls include (1) confusing the EPC2-TI32 (commercial 0 C to +70 C) with the EPC2-TI32N (industrial -40 C to +85 C), (2) omitting the JTAG pull-up on TDI/TDO, which can cause ISP failures, and (3) using the wrong MSEL/PS pin configuration on the FPGA, leading to passive-serial vs JTAG mode mismatch.
Route the JTAG signals (TCK, TMS, TDI, TDO) as a 4-wire daisy-chain with 10 kohm pull-ups on TMS, TDI, and nRESET, matched within +/- 25 mm to avoid skew. The DCLK and DATA outputs to the FPGA should be kept under 50 mm and routed over a continuous ground plane to prevent reflections that cause configuration CRC errors. Place the EPC2-TI32N within 25 mm of the FPGA's passive-serial configuration pins to minimize EMI susceptibility.
Compliance Information
RoHS, REACH, lead-free, and halogen-free status were not explicitly stated in the Verified Web Data. The 'N' suffix in the part number is consistent with lead-free ordering codes per Altera/Intel legacy ordering guidelines, but a certificate of compliance should be requested from Intel FPGA support for procurement documentation. AEC-Q100 is not applicable - this is a configuration PROM, not an automotive-grade IC.
