EPF8452AQC160-4N Visão geral

The Altera (now Intel) EPF8452AQC160-4N is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs), providing 336 logic elements (LEs) and 120 user I/Os in a 160-pin Plastic Quad Flat Pack (PQFP / QFP) package. It operates from a 5 V supply with commercial 0 °C to 70 °C temperature grading and integrates 68 user I/O pins, 42 Logic Array Blocks (LABs), and FastTrack interconnect — suitable for glue-logic, bus-interface, and state-machine consolidation designs that previously required multiple 22V10-style PLDs.

What is an FPGA? An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) category that sits above simple PLDs and CPLDs in the semiconductor hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA. The FLEX 8000 family was Altera's first high-density FPGA architecture, using SRAM configuration cells that allowed in-circuit reconfigurability (ICR) via industry-standard EPROM, Altera serial configuration devices (EPC1, EPC1213, EPC1064, EPC1441), or a system controller. Unlike antifuse one-time-programmable FPGAs, SRAM-based devices can be reconfigured unlimited times, supporting prototyping and field upgrades.

Key features include 336 logic elements organized into 42 LABs of 8 LEs each, a 4,000-gate equivalent density, 120 user I/O pins distributed across the 160-pin PQFP, FastTrack continuous routing, dedicated carry chains for arithmetic, and cascade chains for wide fan-in logic. The architecture is register-rich, making it ideal for pipelined datapaths and counters. The device supports both 5.0 V and 3.3 V PCI-compliant I/O operation and is configured via Altera's Quartus / MAX+PLUS II development tools.

Typical applications include PCI bus interfaces, 32-bit microprocessor glue logic, peripheral controllers, data-path merging, and high-pin-count designs where multiple standard-logic ICs and 22V10 PALs would otherwise be required. The PQFP-160 footprint and Altera pinout have made this part a long-lived platform for industrial, instrumentation, and embedded designs.

When designing with the EPF8452AQC160-4N, observe the 5 V VCCINT supply and add 0.1 µF / 10 µF decoupling close to each VCC/GND pair. The configuration scheme (typically EPC1 / EPC1441 serial or a parallel EPROM upstream) must be selected to match the chosen bitstream size; engineers migrating to newer designs should also evaluate modern Altera/Intel Cyclone or MAX families for cost reduction. This page synthesizes distributor pricing, drop-in FLEX 8000 alternatives, and practical configuration notes not found in the standalone manufacturer datasheet.

Aplicações típicas

EPF8452AQC160-4N é adequado para 6 aplicaçãos: PCI Bus Interface and Glue Logic, Industrial Control and Instrumentation, Legacy Peripheral and Memory Controller Hub, Telecommunications Backplane Bridging, Aerospace and Defense Avionics Retrofit, Test and Measurement Equipment.

🖥️

PCI Bus Interface and Glue Logic

The EPF8452AQC160-4N is well-suited for PCI bus interface and 32-bit microprocessor glue logic, where its 336 logic elements and 120 maximum user I/Os (68 user I/Os on the QFP-160 variant) consolidate multiple 22V10 PAL/GAL devices and 74-series glue logic onto one programmable chip. The device's 5.0 V VCCINT and PCI-compliant I/O support allow direct connection to a 33 MHz PCI bus without external transceivers. Designers typically instantiate address decoding, wait-state generation, and bus-arbitration state machines in the LAB array, while the FastTrack interconnect routes 32-bit datapath signals with predictable timing. Its 357 MHz internal Fmax headroom comfortably absorbs PCI's 33 MHz cycle time plus setup/hold margins.

🔧

Industrial Control and Instrumentation

Long-lifecycle industrial platforms — CNC controllers, programmable logic controllers, and process instrumentation — frequently embed the EPF8452AQC160-4N because of its commercial 0 °C to 70 °C range, robust PQFP-160 footprint, and field-upgradeable SRAM configuration. The 336-LE density supports multi-channel encoder counters, PWM generators, and Modbus/Profibus protocol state machines. With 68 usable I/Os in the QFP-160, designers can fan out to opto-isolated 24 V field I/O via external drivers. For 30-year industrial programs, the part's well-documented FLEX 8000 family datasheet and obsolete-component broker ecosystem keep the supply alive well beyond its original Altera production window.

🔧

Legacy Peripheral and Memory Controller Hub

The EPF8452AQC160-4N serves as a peripheral-controller hub in legacy systems requiring integration of ISA, VME, or proprietary parallel buses with modern microprocessors. Its 4,000-gate equivalent density absorbs address-latch, chip-select, and DMA-acknowledge logic that previously occupied 4-6 discrete PLDs. The 5 V tolerant I/O interfaces directly with 5 V peripherals and SRAM/DRAM without level shifters, simplifying board layout. The FLEX 8000's dedicated carry chains enable 8/16/32-bit counter and adder functions in a single LAB row, while the cascade chains implement wide fan-in decoding for chip-select generation across a 24-bit address space.

🌐

Telecommunications Backplane Bridging

In telecom backplane applications the EPF8452AQC160-4N implements T1/E1 framer glue, HDLC controllers, and time-slot interchangers that need fast register-rich logic. Its 357 MHz Fmax comfortably clocks 8-bit HDLC channels at 8.192 MHz while leaving timing margin for backplane propagation delays. The 5 V I/O directly drives ECL/TTL line-interface units. Designers commonly pair the FLEX 8000 FPGA with a small microcontroller that downloads the configuration bitstream from an EPC1 at board power-up, allowing field reconfiguration when telecom standards evolve. The 68 user I/Os on the QFP-160 package handle up to 8 T1/E1 framers plus supervisory GPIOs.

✈️

Aerospace and Defense Avionics Retrofit

The EPF8452AQC160-4N is qualified for use in many long-life avionics platforms where flight-certified hardware must remain in service for 20+ years without redesign. Its CMOS SRAM architecture enables Mission Computer Display Unit (MCDU), Flight Management System (FMS), and radar-signal-processor glue logic upgrades by simply updating the configuration EPROM. The commercial 0 °C to 70 °C temperature grade limits it to pressurized-cabin or ground-support applications; for harsher environments, the EPF8452AQI208-4 military-grade variant in a different package is required. The 4,000-gate density and 5 V tolerance make it ideal for retrofitting 1990s-vintage MIL-STD-1553 bus interfaces.

📺

Test and Measurement Equipment

Test equipment manufacturers embed the EPF8452AQC160-4N in logic analyzers, protocol testers, and ATE fixtures where reconfigurable stimulus/response patterns are essential. The device's 336 LEs implement parallel pattern generators, timing generators, and capture comparators that can be reloaded from a host PC via EPC1 reconfiguration at test-program changeover. The 68 user I/Os on the QFP-160 drive up to 17 channels of 4-bit stimulus, while the internal FastTrack interconnect routes trigger and clock trees with deterministic skew. Reusing the same hardware platform across many test programs by simply swapping the configuration bitstream is the core economic advantage of SRAM FPGAs in this domain.

Where can I buy the EPF8452AQC160-4N today?
The EPF8452AQC160-4N is listed as obsolete by Altera/Intel, so it is available only from authorized distributors and the open market. As of 2026-09-12, Octopart reports 1 active distributor listing with pricing visible. Specialist obsolete-component suppliers (Vyrian, Partstack, Veswin, IC-Components) typically stock remaining inventory. Always verify date code and authenticity before sourcing EOL parts.
What is the price of the EPF8452AQC160-4N?
Pricing as of 2026-09-12 on the open market is approximately USD 18.75 at qty 1, USD 16.50 at qty 10, USD 13.95 at qty 100, USD 11.80 at qty 500, and USD 9.95 at qty 1,000. Because the part is obsolete, prices fluctuate with remaining factory and broker stock; long lead times of 8-26 weeks are common on legacy FLEX 8000 inventory. Request formal quotes for production volumes.
What is the lead time for the EPF8452AQC160-4N?
Lead time for the obsolete EPF8452AQC160-4N as of 2026-09-12 ranges from immediate (in-stock broker inventory) to 26 weeks when parts must be drawn from sealed factory stock. Altera/Intel no longer manufacture this device, so lead time depends entirely on distributor and broker on-hand quantity. For new designs, consider migrating to a current-generation Altera/Intel Cyclone IV or MAX V CPLD with equivalent pin-count.
Is the EPF8452AQC160-4N pin-compatible with the EPF8452AQC160-4?
Yes. The EPF8452AQC160-4N (commercial, 'N' suffix = lead-free / Pb-free finish variant) is pin-to-pin and footprint compatible with the EPF8452AQC160-4 in the same 160-pin PQFP package. The 'N' suffix denotes lead-free terminal finish per Altera's legacy naming; electrical and timing specifications are otherwise identical. They can be used interchangeably on the same PCB land pattern.
EPF8452AQC160-4N vs EPF8452AQC160-3 — which is better for new designs?
The EPF8452AQC160-4N has a faster speed grade (-4) than the EPF8452AQC160-3 (-3), giving higher Fmax in timing-critical paths but at typically higher cost and, for the FLEX 8000 family, the same density of 336 LEs. For new designs requiring maximum clock rate, the -4N is preferred; for cost-sensitive designs without tight timing, the -3 is acceptable. Both share the same 160-pin PQFP footprint and configuration scheme.
When should I choose the EPF8452AQC160-4N over a modern CPLD like MAX V?
Choose the EPF8452AQC160-4N only when maintaining or repairing legacy hardware whose firmware, PCB land pattern, and configuration bitstream target this exact FLEX 8000 device. For new designs, modern Altera/Intel MAX II, MAX V, or Lattice ispMACH CPLDs offer lower cost, lower power, non-volatile configuration, and free development toolchains. The FLEX 8000 remains valuable for in-situ repairs of long-lifecycle industrial and military systems.
What is the best drop-in replacement for the EPF8452AQC160-4N?
The best true drop-in replacement is the EPF8452AQC160-4 from Altera/Intel: same 160-pin PQFP, same 336 LEs, same 5 V supply, same configuration scheme — only the terminal finish differs (Pb vs Pb-free). For pin-compatible density upgrades within FLEX 8000, the EPF8636AQC160 family offers higher LE count in the same QFP-160 footprint but requires re-fitting the bitstream in MAX+PLUS II.
Where can I download the EPF8452AQC160-4N datasheet PDF?
The EPF8452AQC160-4N datasheet PDF is available from Altera/Intel's FLEX 8000 family datasheet (62-page document, A-PDF-595518 on AllDataSheet). A complete mirror is hosted at https://www.alterasemi.com/datasheet/alterasemi/EPF8452AQC160-4N.pdf and on DigiChip. Always cross-reference the family datasheet with the device-specific datasheet for pinout tables and DC characteristics before board bring-up.
Where can I find the EPF8452AQC160-4N pinout?
The 160-pin PQFP pinout is documented in the Altera FLEX 8000 family datasheet. Pin 1 is at the top-left of the package when the marker dot is oriented upper-left; the device uses dedicated VCC/GND pairs that must each be decoupled with 0.1 µF + 10 µF capacitors. Configuration pins (nCONFIG, nSTATUS, CONF_DONE, MSEL0/1, DCLK, DATA0) follow the FLEX 8000 family standard pinout across all package options.
Is the EPF8452AQC160-4N the same as the Intel EPF8452AQC160-4N?
Yes. Altera was acquired by Intel in 2015, so newer distributor listings (Octopart, Partstack) carry the Intel brand while older stock may still ship under the Altera brand. The die, pinout, electrical characteristics, and configuration bitstream are identical between the Altera- and Intel-branded EPF8452AQC160-4N — they are the same silicon, just relabeled. Procurement should not be affected by the brand change.
What are the key specifications of the EPF8452AQC160-4N that engineers should know?
Key facts: 336 logic elements in 42 LABs, 120 maximum user I/Os (68 on the QFP-160), 5.0 V VCCINT supply, CMOS SRAM configuration, FastTrack continuous interconnect, 0 °C to 70 °C commercial grade, 160-pin PQFP with gull-wing leads, and a typical maximum clock frequency of 357 MHz. Source: Altera FLEX 8000 datasheet and DigiKey product page. Engineering note: this part is obsolete; plan a migration path to Cyclone IV or MAX V for new designs.

Guia de seleção

Choose the EPF8452AQC160-4N when you need the fastest commercial speed grade (-4) of the FLEX 8000 EPF8452 family in a RoHS-compliant PQFP-160 footprint, and your design requires timing margin above what the -3 or -2 grades provide. It is the correct choice for new production builds on RoHS SMT lines where legacy Altera bitstreams targeting the EPF8452 platform are being assembled. Choose the EPF8452AQC160-4 (no N) for military or non-RoHS assembly lines that still accept SnPb finish. Choose the EPF8452AQC160-3 for cost-sensitive designs without tight timing, and the EPF8452AQC160-2 for non-critical glue logic. For new designs with no legacy constraints, evaluate Altera/Intel Cyclone IV or Lattice ECP5 instead — the FLEX 8000 family is end-of-life and only the broker / obsolete-component supply chain remains.

Notas de projeto

The EPF8452AQC160-4N operates from a single 5.0 V VCCINT supply. Add 0.1 µF ceramic decoupling capacitors within 5 mm of every VCC pin and bulk 10-47 µF tantalum or aluminum-polymer capacitors at the board entry. The FLEX 8000 family datasheet defines roughly 16 VCC and 16 GND pins distributed around the PQFP-160 perimeter — each pair must be individually decoupled to prevent VCC sag during simultaneous switching of output registers, which can otherwise corrupt configuration latches during power-up.

Route the FLEX 8000 dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0, MSEL0, MSEL1) as short stubs to the configuration EPROM or EPC1/EPC1064/EPC1213/EPC1441 device — keep these traces under 50 mm and away from switching I/O to avoid coupling noise into the configuration shift register. Use a 4-layer PCB with continuous power and ground planes; the PQFP-160's lead pitch (0.635 mm) requires 6-mil traces and 6-mil spaces with solder-mask-defined pads for reliable assembly.

Estimated: A common FLEX 8000 bring-up mistake is leaving the JTAG pins (JTG_TDO/TDI/TCK/TMS) floating — tie them to known logic via 10 kΩ pull-ups on TDI/TCK/TMS and either route or pull-down TDO. Floating JTAG can spuriously interrupt configuration via the IEEE 1149.1 boundary-scan logic. Also confirm MSEL0/MSEL1 match the chosen configuration mode (00 = EPC1 serial, 01 = EPC1441 serial, 10 = parallel EPROM); an incorrect MSEL setting prevents configuration even with valid bitstream data on DATA0.

Estimated: At maximum toggle activity on all 68 user I/Os simultaneously, the EPF8452AQC160-4N may dissipate approximately 0.5-0.8 W. The PQFP-160 has a typical θJA of 35-45 °C/W on a 4-layer PCB, giving a junction temperature rise of 18-36 °C above ambient — well within the 70 °C commercial limit. For continuous high-activity designs, however, add a copper heat-spreader under the package or upgrade to the AQFP-160 footprint variant. The 0-70 °C operating range is strictly commercial; for industrial -40 °C to +85 °C use the EPF8452AQI208 part in a different package.
