EPF8452AQC160-4 Visão geral

The Altera (Intel) EPF8452AQC160-4 is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs) with 4,000 usable gates, 336 logic cells, and 68 user I/Os, housed in a 160-pin BQFP/PQFP package. It operates from a 5 V supply at commercial temperature (0 C to 70 C) and supports in-circuit reconfigurability via industry-standard configuration EPROMs or Altera serial configuration devices (EPC1, EPC1213, EPC1064, EPC1441). The device is fabricated on a 0.42 um CMOS process and supports system clock frequencies up to 125 MHz.

A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that uses an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells to implement arbitrary digital logic. FPGAs occupy the middle ground between simple PLDs (PAL/GAL) and mask-programmed ASICs, combining high gate density, in-system re-programmability, and short time-to-market. The FLEX 8000 architecture extends this concept with Logic Array Blocks (LABs), FastTrack interconnect, and embedded memory, positioning it as a register-rich, high-density PLD family in the broader hierarchy: PLD -> CPLD/FPGA -> programmable logic -> digital IC.

Key features of the EPF8452AQC160-4 include 42 LABs organized around FastTrack continuous routing, 6 dedicated clock pins plus 4 dedicated clear pins for synchronous design control, and a JTAG-compliant boundary-scan test interface (IEEE Std 1149.1) for board-level test access. The 0.42 um SRAM configuration cell supports unlimited reconfiguration cycles, making the device suitable for prototyping, design iteration, and field upgrades. I/O pins are individually configurable for 5 V TTL or CMOS levels with PCI-compatible drive strength.

Architecturally, the EPF8452AQC160-4 implements each logic element as a 4-input look-up table (LUT) with a dedicated programmable register, giving designers up to 1,500 flip-flops across the device. Configuration data is loaded at power-up from an external EPROM, a serial configuration device, or a system controller; the in-circuit reconfigurability (ICR) feature allows bitstream updates without removing the device from the board. MultiVolt I/O compatibility supports mixed 3.3 V/5 V bus interfaces when used with external clamping.

Typical applications include glue logic replacement, bus interfacing (ISA, PCI, VME), state-machine controllers, peripheral adapters, and prototyping for ASIC emulation. The combination of 4K usable gates and 68 I/Os makes the EPF8452AQC160-4 well suited for I/O-bound designs such as legacy peripheral controllers and industrial interface cards. Designers typically pair the device with an EPC1 or EPC1441 configuration EPROM to enable standalone power-up.

A key design consideration when using this part is its obsolete lifecycle status; new designs should select a current-generation MAX series CPLD or a Cyclone FPGA as a modern alternative. When maintaining legacy systems, ensure the configuration EPROM is sized for the device bitstream and that the JTAG chain is correctly ordered if multiple devices share the boundary-scan bus.

Legacy Peripheral Replacement Cards

The EPF8452AQC160-4 is commonly used in legacy peripheral replacement cards that emulate discontinued proprietary bus interfaces, parallel ports, or custom peripheral ASICs. Designers load a configuration bitstream from a serial EPROM at power-up, then present the legacy interface signals on the 68 user I/Os with 5 V CMOS drive. The in-circuit reconfigurability (ICR) feature lets field engineers swap behavior by replacing the configuration EPROM without removing the card. This makes the EPF8452AQC160-4 a popular choice for sustaining industrial control systems that must run for decades without redesign.

What is the logic capacity of the EPF8452AQC160-4?
The EPF8452AQC160-4 provides 4,000 usable gates organized as 336 logic cells across 42 Logic Array Blocks (LABs), with up to 1,500 flip-flops available for registered designs. According to the Altera FLEX 8000 datasheet, the device sits in the mid-density tier of the family, supporting designs that exceed simple PLD capacity but do not require mask-programmed ASICs. Designers should consult the device utilization guide when targeting >80% utilization.
What package does the EPF8452AQC160-4 use?
The EPF8452AQC160-4 ships in a 160-pin BQFP (also called PQFP) surface-mount package, with 68 user I/Os and the remaining pins allocated to power, ground, configuration, JTAG, and dedicated clock/clear inputs. According to the Altera package outline, this BQFP-160 footprint matches other FLEX 8000 family members with the same pin count, enabling PCB reuse across density upgrades within the family. The thermal resistance and lead-pitch match JEDEC surface-mount standards for PQFP packages.
Is the EPF8452AQC160-4 still in production?
No, the EPF8452AQC160-4 is obsolete and no longer manufactured by Altera (now Intel FPGA). Distributors such as DigiKey and Mouser historically list remaining stock and authorized-channel inventory, but the part is not recommended for new designs. For new projects, choose a current-generation MAX series CPLD or Cyclone FPGA as a modern functional replacement, then verify timing and pinout compatibility during port.
What is the difference between the EPF8452AQC160-4 and the EPF8452AQC160-3?
The EPF8452AQC160-4 and EPF8452AQC160-3 share the same 160-pin BQFP package, the same 4,000 usable gates, and identical logic capacity; the suffix -4 vs -3 indicates a different speed grade. According to Altera FLEX 8000 datasheet ordering information, the -4 is the slower speed grade and the -3 is the faster grade; Fmax differs but logic, I/O, and configuration are pin-compatible. Designers can substitute -3 for -4 in legacy boards with no PCB rework.
What is the difference between the EPF8452AQC160-4 and the EPF8452AGC160-3?
Both parts share the 160-pin BQFP footprint and the same 4,000-gate FLEX 8000 architecture, but they differ in the speed grade and operating temperature. The AQC160-4 operates commercial 0 C to 70 C at speed grade -4; the AGC160-3 typically denotes the same gate count with a different speed grade and possibly a different I/O standard set. Pin-to-pin compatibility should be verified against each datasheet before PCB swap.
What is the supply voltage for the EPF8452AQC160-4?
The EPF8452AQC160-4 requires a single 5 V supply for the core and I/O. According to the Altera FLEX 8000 datasheet, the device is not 3.3 V tolerant on I/O banks in its standard configuration; mixed-voltage systems need external level shifters. Designers should place 0.1 uF decoupling capacitors adjacent to every VCC pin and a bulk capacitor near the package power entry to meet inrush during configuration.
How is the EPF8452AQC160-4 configured at power-up?
The EPF8452AQC160-4 is configured at system power-up from an external industry-standard parallel EPROM, an Altera serial configuration device (EPC1, EPC1213, EPC1064, or EPC1441), or data provided by a system controller. According to the Altera FLEX 8000 datasheet, configuration is loaded into SRAM cells; in-circuit reconfigurability (ICR) allows bitstream updates without removing the device. Designers should size the configuration EPROM to match the device bitstream length and follow the configuration timing diagram.
Does the EPF8452AQC160-4 support JTAG boundary-scan?
Yes, the EPF8452AQC160-4 includes a JTAG-compliant boundary-scan test interface conforming to IEEE Std 1149.1. According to the Altera FLEX 8000 datasheet, the JTAG pins (TDI, TDO, TMS, TCK) allow board-level interconnect testing and can be chained with other JTAG devices. Designers must correctly order the JTAG chain and provide a TRST or proper TMS power-up sequence to avoid inadvertent entering of test modes.
What is the maximum operating frequency of the EPF8452AQC160-4?
The EPF8452AQC160-4 supports internal frequencies up to 125 MHz, depending on logic utilization and routing. According to the Altera FLEX 8000 datasheet, the -4 speed grade is the slowest of the family; the -3 grade is faster for timing-critical designs. Designers should consult the fMAX specification for the specific speed grade and confirm timing closure with the Altera MAX+PLUS II or Quartus design software.
Where to buy EPF8452AQC160-4 online?
As of 2026-09-12, the EPF8452AQC160-4 is available primarily from authorized distributors carrying obsolete stock, including DigiKey (Digi-Key part 1468800-1-ND), Mouser, Arrow, Octopart-indexed suppliers, and independent obsolete-component specialists. Because the part is obsolete, lead times vary and prices are not stable; request quotes for production volumes. Always verify traceability and inspect for counterfeit risk when sourcing obsolete FPGAs.

What is the lead time for EPF8452AQC160-4?
As of 2026-09-12, lead time for the EPF8452AQC160-4 is not standard stock and is generally BackOrder or quote-only at major distributors because the part is obsolete. Lead time depends on remaining distributor inventory or authorized-channel pulls; expect 8-16 weeks for production quantities when ordering through specialized obsolete-component brokers. For new designs, switch to a current-generation FPGA to eliminate lead-time risk.
EPF8452AQC160-4 vs EPF8452AQC160-3 - which is better for legacy replacement?
The EPF8452AQC160-4 and EPF8452AQC160-3 share the same 160-pin BQFP package and 4,000-gate architecture, so either can be used for legacy replacement with no PCB rework. The -3 grade is the faster speed grade with higher fMAX; the -4 grade is the slower grade. For legacy maintenance where timing closure was already achieved with the -4 grade, the -4 is the correct drop-in; for timing-critical legacy repairs, the -3 is functionally equivalent and faster.
What is the best drop-in replacement for EPF8452AQC160-4?
The best drop-in replacement for the EPF8452AQC160-4 in legacy maintenance is the EPF8452AQC160-3, which shares the same 160-pin BQFP footprint, the same 4,000-gate logic capacity, the same 68 I/Os, and the same 5 V supply, differing only in speed grade. According to Altera FLEX 8000 ordering information, the -3 is the faster speed grade in the same family and is pin-compatible. For new designs, a MAX II CPLD or Cyclone series FPGA is recommended instead.
Where to download EPF8452AQC160-4 datasheet PDF?
The EPF8452AQC160-4 datasheet PDF (a 62-page document titled 'Programmable Logic Device Family') is available from Altera's historical archive via distributors such as AllDatasheet (all datasheet.com part ID 595518), FPGAkey, Jotrin, and the original Altera datasheet index. According to AllDatasheet metadata, the PDF is approximately 967 KB and covers the FLEX 8000 device family. Engineers should also retain the MAX+PLUS II or Quartus legacy design documentation for the part.
Where to find EPF8452AQC160-4 pinout?
The EPF8452AQC160-4 pinout is documented in the Altera FLEX 8000 datasheet, available as a PDF download from AllDatasheet, FPGAkey, and the original Altera archive. The 160-pin BQFP package assigns 68 pins to user I/O, dedicated clock/clear pins, JTAG, configuration, power, and ground. Designers should consult the package outline and pinout table in the datasheet to map signals before PCB layout or repair work.

Guia de seleção

Choose the EPF8452AQC160-4 only when repairing a legacy board that was originally designed for the -4 speed grade and must be matched 1:1. For timing-critical legacy repairs where higher fMAX headroom is needed, select the EPF8452AQC160-3 (same package, faster speed grade). For industrial or defense sustainment programs, select the EPF8452AGC160-3 or EPF8452AGC160-3N for extended temperature. For lead-free RoHS compliance, the EPF8452AGC160-3N is the right drop-in. For all new designs, do not select any FLEX 8000 part - move to a current-generation MAX series CPLD or Cyclone FPGA with active lifecycle support and updated design tooling.

Notas de projeto

Estimated: at 5 V supply with 50% I/O toggling at 25 MHz, the EPF8452AQC160-4 core consumes roughly 0.4-0.6 W. Place one 0.1 uF decoupling capacitor adjacent to every VCC pin (6 pins total) and a single 10 uF tantalum bulk capacitor near the package power entry. During configuration, the device draws inrush current; ensure the 5 V rail can source the peak without collapsing. Designers should measure rail voltage during power-up with an oscilloscope to verify clean configuration.

Route the dedicated clock inputs (CLK0-CLK5) with controlled-impedance traces and keep them short. Place the configuration EPROM (EPC1, EPC1213, EPC1064, or EPC1441) within 50 mm of the FLEX 8000 device to meet configuration timing; long traces degrade the configuration signal integrity. The JTAG chain (TDI, TDO, TMS, TCK) should be daisy-chained with no stubs. Provide a TRST pull-down or proper TMS power-up sequence per IEEE 1149.1 to avoid latching into test mode at power-up.

Do not confuse the EPF8452AQC160-4 with the EPF8452AQC160-3 or -2 speed grades when ordering legacy replacement parts; the speed grade suffix -4, -3, -2 denotes FMAX tier, not pin count or logic capacity. The 160-pin BQFP footprint is identical across all three, but timing closure assumptions differ. Do not apply 3.3 V signals directly to the I/O without external clamping; the FLEX 8000 I/O is 5 V CMOS. Avoid using the EPF8452AQC160-4 in new designs - the part is obsolete and Intel/Altera does not recommend it for new starts.
