EPF8452AQC160-2 - 4K Gates FLEX 8000 FPGA, 160-PQFP | Intel
MPN: EPF8452AQC160-2 ✗ پایان تولیدEPF8452AQC160-2 نمای کلی
A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) whose logic and interconnections are configured by loading SRAM configuration bits at system power-up. Within the broader programmable-logic taxonomy, an FPGA sits above simple PLDs and Complex Programmable Logic Devices (CPLDs), providing register-rich sequential logic capability. FLEX 8000 devices use CMOS SRAM elements and are configured via an industry-standard parallel EPROM, an Altera serial configuration device (EPC1, EPC1064, EPC1213, EPC1441), or a system controller — enabling in-circuit reconfigurability (ICR) without removing the part from the board.
Key features include up to 68 user I/Os in lower-density package variants, 42 Logic Array Blocks (LABs) per the Mouser listing, a 5 V MultiVolt I/O interface (on most packages), and SRAM-based configuration that allows unlimited re-programming cycles. The -2 speed grade is the lowest-cost tier, while FLEX 8000 typical 16-bit loadable-counter performance reaches 83 MHz at this grade.
Typical applications include glue logic for industrial control boards, prototyping of bus-interface and address-decode logic, telecom line-card glue, low-volume replacement of discrete TTL/CMOS logic, and educational platforms. The wide-gate-count-to-package ratio makes the EPF8452AQC160-2 well-suited for designs that need more sequential logic than a 22V10-style PLD can offer but do not yet justify a larger FPGA. Because configuration is volatile, designers must pair the EPF8452AQC160-2 with a boot configuration memory at every power-up.
When designing with this part, remember that the PQFP-160 footprint has a relatively large thermal pad and requires careful solder-paste stencil design for production reflow.

کاربردهای معمول
EPF8452AQC160-2 مناسب است برای 6 کاربردs: Industrial Glue Logic and Bus Interface, Telecom Line-Card Control Logic, Legacy Replacement of Discrete TTL/CMOS Logic, Educational FPGA and Prototyping Platforms, Test and Measurement Front-End Logic, Aerospace and Defense Legacy Sustainment.
Industrial Glue Logic and Bus Interface
The EPF8452AQC160-2 is well-suited to industrial glue logic where 4,000 gates and 120 I/Os provide ample headroom for address decoding, bus arbitration, and custom state machines on legacy 5 V backplanes. Its SRAM-based configuration supports field updates without board rework, while the commercial 0–70 °C range covers most factory-floor enclosures. Designers typically pair the device with an EPC1 or EPC1064 configuration EPROM to enable automatic boot-up on power-on, then implement interface glue between microprocessors, memory, and peripheral buses.
پیشنهادی
Telecom Line-Card Control Logic
In telecom line cards the EPF8452AQC160-2 historically served as a flexible glue layer between TDM framers, HDLC controllers, and switch-fabric ASICs. Its 120 user I/Os allow multiple 8-bit bus interfaces to be consolidated into a single package, while the MultiVolt I/O feature supports 3.3 V peripherals alongside 5 V backplane logic. The 5 V tolerance and 0–70 °C commercial range match central-office environment requirements, and the SRAM configuration allows service providers to deploy feature updates without truck rolls.
پیشنهادی
Legacy Replacement of Discrete TTL/CMOS Logic
When a discrete TTL or 4000-series CMOS design approaches 30–50 ICs, the EPF8452AQC160-2 can replace an entire board's worth of glue logic in a single 160-PQFP, reducing board area, power, and assembly cost. Designers port their existing logic to VHDL or Verilog and synthesize into the FLEX 8000 architecture, often achieving equivalent functionality at one-tenth the board area. The -2 speed grade is sufficient for most glue-logic clock rates below 50 MHz, and the 5 V I/O directly interfaces with legacy peripheral ICs without level shifters.
پیشنهادی
Educational FPGA and Prototyping Platforms
The EPF8452AQC160-2 is used in university-level digital design labs and retro-computing projects because its FLEX 8000 architecture is well documented in textbooks and Quartus II legacy tutorials support the device. Students can implement 16-bit loadable counters (rated at 83 MHz in the -2 grade) and 16-to-1 multiplexers (9.5 ns) as taught exercises, and the 120 I/Os accommodate many parallel breakout pins. The 160-PQFP package is breadboard-friendly with appropriate breakout adapters, and obsolete-market pricing keeps lab kit costs manageable.
پیشنهادی
Test and Measurement Front-End Logic
In test and measurement equipment, the EPF8452AQC160-2 implements custom timing generators, pattern sequencers, and channel-multiplexers that need precise control over many parallel signals. Its 120 I/Os allow direct fanout to front-panel connectors or pin-driver ASICs, while the SRAM configuration supports on-the-fly test-pattern reloading between test runs. The 5 V I/O tolerance matches TTL-level instrumentation buses, and the commercial 0–70 °C temperature range covers most laboratory environments without derating.
پیشنهادی
Aerospace and Defense Legacy Sustainment
Long-lifecycle aerospace and defense platforms still in service — such as avionics, radar, and military communications — often rely on FLEX 8000 designs that cannot be re-engineered without expensive re-certification. The EPF8452AQC160-2 supports these sustainment programs as a form-fit-function replacement of failed units, with same-die -3 and -4 speed-grade variants available when higher performance is needed. Authorized-distributor stock and independent aftermarket sources remain the primary channels because the part has been obsolete for years.

یادداشت‌های طراحی
The EPF8452AQC160-2 requires a clean 5 V supply at 4.75 V to 5.25 V for the VCCINT pins (5 V core) plus a separate VCCIO rail that can be tied to 5 V or 3.3 V depending on MultiVolt I/O configuration. Decouple each VCCINT pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, and add a single 10 µF bulk tantalum or ceramic near the package. The SRAM configuration is volatile — every power-up must be followed by a configuration load from an EPC1, EPC1064, EPC1213, EPC1441, or a parallel EPROM. Add a reset supervisor to ensure clean VCC ramp before configuration begins.
The PQFP-160 package has a 0.5 mm pin pitch (typical for QFP-160) and gull-wing leads on all four sides. Use a JEDEC-standard land pattern with 0.30 mm × 1.50 mm pads and solder mask defined (SMD) openings for best solder-joint reliability. The package body is approximately 28 × 28 mm with a thermal pad on the underside that should be soldered to a copper pour to improve heat dissipation — without it, junction temperature can exceed 100 °C at high toggle rates. Stencil design should be 100 µm stainless steel with reduced aperture ratios on fine-pitch perimeter pads to prevent solder bridging.
Three pitfalls commonly trip first-time FLEX 8000 designers. (1) Forgetting the configuration EPROM — without it, the FPGA does nothing at power-up and all I/Os stay tri-stated; an EPC1 or EPC1064 must be on the board or the design will appear completely dead. (2) Mixing VCCIO voltages — the I/O bank is 5 V tolerant only when VCCIO = 5 V; setting VCCIO = 3.3 V disables 5 V input tolerance and can damage upstream drivers. (3) Ignoring the configuration mode pins — MSEL0/MSEL1 must be tied correctly to select the configuration scheme; floating pins cause intermittent configuration failures. Always verify MSEL strapping against the FLEX 8000 datasheet's configuration chapter.
