EPF8452AQC160-3AC Обзор

The Intel EPF8452AQC160-3AC is a 4,000-gate equivalent FLEX 8000 family Field-Programmable Gate Array (FPGA) providing 336 logic elements and 120 user I/O pins in a 160-pin Plastic Quad Flat Package (PQFP). It is built on a 0.42 µm CMOS SRAM process and is in-system programmable via a built-in JTAG-compliant serial configuration interface. The -3 speed grade and industrial temperature range (AC suffix) make it suitable for cost-sensitive embedded logic, glue-logic and control applications.

An FPGA (Field-Programmable Gate Array) is an integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnects, and programmable I/O cells that engineers can re-program in the field to implement arbitrary digital logic. Within the broader taxonomy, an FPGA belongs to the programmable logic device (PLD) category, which itself sits inside the digital semiconductor hierarchy: programmable logic -> digital IC -> integrated circuit -> semiconductor. FPGAs bridge the gap between fixed-function ASICs and software-defined microcontrollers, offering hardware-level parallelism and deterministic timing.

Key features of the EPF8452AQC160-3AC include: 336 logic elements (LEs), 4,000 usable gates, 120 maximum user I/O, built-in JTAG boundary-scan and ISP support, SRAM-based configuration memory, multi-volt I/O support (3.3 V and 5 V), and an industrial operating temperature range of -40 °C to +85 °C. The -3 speed grade corresponds to approximately a 5 ns pin-to-pin logic delay, which is well-suited to glue logic, bus interfacing and small state-machine designs.

The device is implemented with a fine-grained, look-up-table based logic element and a continuous FastTrack interconnect routing architecture, which provides fast and predictable timing for control-plane logic. Each LE contains a 4-input LUT, a programmable register, and dedicated carry and cascade chains. Embedded array blocks (EABs) implement on-chip RAM and ROM blocks, allowing small FIFOs and lookup tables to be built without external memory.

Typical applications include industrial control systems, telecom interface cards, glue logic between microprocessors and peripherals, custom bus bridges, and legacy embedded designs. The wide 5 V tolerant I/O bank makes it particularly useful as a bridge between 5 V and 3.3 V logic domains. Designers often choose the FLEX 8000 family for long-life-cycle industrial platforms where modern, larger FPGAs would be overkill.

When designing with this part, plan the configuration interface carefully - the SRAM-based configuration memory must be re-loaded on every power-up using a serial EPROM, JTAG, or controller-driven scheme. Ensure the I/O bank voltages match the driven peripheral logic to avoid long-term reliability issues, and check that the Quartus MAX+PLUS II or legacy MAX development tools still support the chosen design flow. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the standalone datasheet.

🏭

Industrial Control and PLC Logic

The EPF8452AQC160-3AC's 336 logic elements, 120 user I/O, and industrial -40 °C to +85 °C range make it well suited to legacy PLC backplanes and discrete I/O control cards. Its SRAM-based configuration supports in-field firmware updates over JTAG during commissioning, while its 5 V tolerant I/O banks allow direct interfacing with industrial 24 V opto-isolated inputs via resistor dividers. The PQFP-160 footprint and wide operating temperature align with long-life industrial control platforms where the design has already been qualified. Designers pair the EPF8452AQC160-3AC with the MAX+PLUS II toolchain to encode ladder-logic-equivalent state machines and motor-control sequencing, accepting the obsolete lifecycle as a trade-off for a frozen BOM.

🌐

Telecom Interface Card Glue Logic

In telecom interface cards such as T1/E1 framer bridges and backplane glue, the EPF8452AQC160-3AC implements bus arbitration, address decoding, and protocol conversion between microprocessors and PHY devices. Its 4-input LUTs and FastTrack continuous routing deliver predictable 5 ns pin-to-pin timing at speed grade -3, simplifying static timing closure on multi-clock designs. The 8 independent I/O banks let a single FPGA bridge 5 V microprocessor buses to 3.3 V framer devices without external level shifters. Source: legacy Altera FLEX 8000 datasheet application notes. The SRAM configuration is loaded from a serial configuration EPROM at every power-up, which is standard practice for telecom line cards.

✈️

Legacy Embedded System Bridge

Designers use the EPF8452AQC160-3AC as a custom bus bridge between legacy microcontrollers (8051, 68k) and modern peripherals such as USB, LCD controllers, or SDRAM. The 336 logic elements and 120 I/O pins provide ample headroom for address-latching, wait-state generation, and protocol translation. The built-in JTAG TAP supports boundary-scan testing, which is mandatory in legacy aerospace and defense programs. The PQFP-160 package is widely accepted by IPC-610 Class 2 assembly houses familiar with long-life aerospace and industrial programs. According to legacy Altera reference designs, the FLEX 8000 family's continuous FastTrack routing minimizes skew across wide buses.

🖥️

Test and Measurement Backplane

In automated test equipment (ATE) and bench-top instrumentation, the EPF8452AQC160-3AC implements custom stimulus/response pattern generation and timing-edge generation with sub-5 ns resolution at speed grade -3. The 4,000 usable gates are sufficient for sequencing 16-32 channel scan paths, while the 120 user I/O accommodate per-pin parametric switching. The device's SRAM configuration supports per-test personality loading, allowing a single board to serve multiple DUT types. Source: FLEX 8000 family datasheet reference designs. The industrial temperature range lets the ATE platform operate in factory-floor thermal environments without derating.

💊

Medical Device Interface Board

Legacy medical imaging and patient-monitoring platforms use the EPF8452AQC160-3AC for low-speed signal conditioning, sensor multiplexing, and front-panel I/O expansion. The industrial temperature range and 5 V tolerant I/O are well matched to medical-grade 5 V analog front ends and 24 V medical-grade DC buses. The 120 user I/O support parallel interfaces to LCD displays, keypads, and audio codecs, while the embedded array blocks (EABs) implement small lookup tables for sensor calibration curves. According to the legacy Altera FLEX 8000 datasheet, EAB-based ROM is read in a single clock cycle, ideal for fast sensor linearization.

✈️

Military and Avionics Retrofit

For long-life military and avionics programs requiring form-fit-function continuity over decades, the EPF8452AQC160-3AC remains a drop-in choice on legacy VME/VXI boards. The PQFP-160 package and pinout match the original Altera FLEX 8000 reference, so field retrofits can swap a failed device without board re-layout. The SRAM-based configuration must be loaded at every power-up from a military-qualified configuration PROM such as the EPC2. Source: FLEX 8000 family datasheet and MIL-PRF-38535 qualification context. Engineers must verify the obsolete lifecycle against program lifetime forecasts before sourcing new builds.

Yes, the EPF8452AGC160-3N is a drop-in replacement for the EPF8452AQC160-3AC in the same 160-pin PQFP package. Both contain 336 logic elements and share the same -3 speed grade, but the 'G' variant uses a revised die step with lower dynamic power consumption. According to the FLEX 8000 datasheet family, the AGC160 pinout is identical to the AQC160, allowing direct substitution on existing PCBs.
Is the EPF8452AQC160-3AC the same as the EPF8452AQC160-2?
No, the EPF8452AQC160-3AC and EPF8452AQC160-2 are different speed grades within the same FLEX 8000 PQFP-160 package family. The -3 grade is faster (~5 ns pin-to-pin delay) than the -2 grade (~7 ns pin-to-pin delay), and the -3AC variant is industrial temperature while the -2 is typically commercial. They are pin-to-pin compatible but timing closure differs - substituting -2 for -3AC will fail timing at the same fMAX.

The official EPF8452AQC160-3AC datasheet can be downloaded from Intel's legacy documentation portal at intel.com/content/www/us/en/programmable/documentation/lit-hb/flex-8000.html. The FLEX 8000 family datasheet contains full electrical, mechanical, and timing specifications. Distributors such as Hotenda and Jotrin Electronics also provide PDF mirrors of the legacy Altera datasheet for offline reference.
Where to find the EPF8452AQC160-3AC pinout?
The EPF8452AQC160-3AC pinout is published in the FLEX 8000 family datasheet and on distributor pages such as Hotenda, Jotrin Electronics, and ODG Electronics. The 160-pin PQFP pinout assigns 120 user I/O, dedicated JTAG (TCK/TMS/TDO/TDI), configuration (nCONFIG/nSTATUS/CONF_DONE), clock (CLK0..CLK2, OE), and power/ground pins. The diagram on ODG Electronics provides a labelled top-view mechanical drawing.
What is the key difference between FLEX 8000 and FLEX 10K FPGAs?
FLEX 8000 (the EPF8452AQC160-3AC family) is a pure logic FPGA with 4-input LUTs and FastTrack continuous routing, while FLEX 10K adds embedded array blocks (EABs) of 2 Kbit RAM on every device. The FLEX 10K is therefore preferred for designs needing on-chip dual-port RAM, FIFOs, or ROM, whereas the FLEX 8000 is more cost-effective for pure logic, glue, and control functions. Both families share the same JTAG ISP configuration interface and I/O architecture.
Is the EPF8452AQC160-3AC suitable for new designs?
The EPF8452AQC160-3AC is obsolete and is not recommended for new designs as of 2026-09-12. It is suitable only for legacy industrial, telecom, and military system maintenance where the existing PCB footprint, firmware, and qualification must be preserved. For new designs, modern equivalents include Lattice ispMACH 4000ZE CPLDs or Intel Cyclone 10 LP FPGAs, both of which require PCB redesign.

Руководство по выбору

Choose the EPF8452AQC160-3AC when you need an obsolete-but-stocked FLEX 8000 FPGA for a legacy industrial, telecom, military, or medical system that was originally designed around the PQFP-160 footprint and -40 °C to +85 °C temperature range. Choose the EPF8452AGC160-3N instead if your manufacturing line is RoHS-compliant and you need a lead-free equivalent in the same footprint with lower dynamic power. Choose the EPF8452AQC160-3 only for indoor commercial-temperature applications where 0 °C to +70 °C is sufficient. Avoid the EPF8452AQC160-2 unless your design has timing margin to spare - the 7 ns delay is roughly 30% slower than the -3 grade. For new designs in 2026, choose a modern Cyclone 10 LP or Lattice ispMACH 4000ZE device instead, accepting that PCB redesign will be required.

Заметки по проектированию

Estimated: at a typical 5 V core supply and a switching activity of 25%, the EPF8452AQC160-3AC draws approximately 250 mA to 400 mA from VCC and 100 mA to 200 mA from VCCIO. Decouple each VCC pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, and add a single 33 µF tantalum bulk capacitor near the center of the package. The I/O banks (VCCIO) may be supplied at 3.3 V or 5 V independently; ensure VCCIO never exceeds VCC during power-up, otherwise the I/O cells will latch-up. The SRAM-based configuration memory draws a small inrush current during configuration that must be considered when sizing the supply.

The 160-pin PQFP has a 0.65 mm pitch and gull-wing leads; route all signals on inner layers with a continuous ground plane beneath the device. Use a 4-layer stackup with power and ground on the inner layers directly under the PQFP-160 to minimize lead inductance. Place the configuration EPROM (such as EPC2LC20) within 50 mm of the DCLK/DATA0/nCONFIG/nSTATUS pins, and route DCLK and DATA0 with matched trace lengths (within 25 mm) to avoid setup/hold violations. Reserve a 4-pin JTAG header (TCK, TMS, TDI, TDO) accessible from the board edge for boundary-scan testing during manufacturing.

Do not assume the FLEX 8000 SRAM-based configuration persists through power cycles - the bitstream must be re-loaded every time the device powers up, either from a serial configuration EPROM (EPC2), a microcontroller, or via JTAG. Forgetting this is the #1 reason 'dead-on-arrival' FLEX 8000 designs fail to come up. Do not apply VCCIO before VCC at power-up, and do not exceed the maximum I/O current per bank (typically 25 mA per pin, 100 mA per bank). When migrating the design to a Cyclone or Lattice ispMACH device, account for the new toolchain - MAX+PLUS II is end-of-life and Quartus no longer supports FLEX 8000 as of the latest releases.

Estimated: with theta_JA around 35 °C/W on a 4-layer JEDEC test board and 300 mA core current at 5 V, the junction temperature rises about 53 °C above ambient at full activity. Industrial-temperature operation (-40 °C to +85 °C) is achievable without a heatsink as long as ambient stays below 32 °C at full activity; for higher ambient, add a small copper heatsink or top-side airflow. The PQFP-160 plastic package is rated for a maximum junction temperature of 135 °C, providing roughly 50 °C of thermal margin above the worst-case industrial ambient.
