EPF8452AGC160-3N - FLEX 8000 FPGA 4K Gates 125MHz 5V 160-CPGA | Altera
MPN: EPF8452AGC160-3N ✗ Cuối đờiEPF8452AGC160-3N Tóm tắt
A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), interconnected via a programmable routing fabric, surrounded by programmable I/O cells. FPGAs sit above programmable logic devices (PLDs/CPLDs) and below ASICs in the design complexity hierarchy, offering hardware-level parallelism for glue logic, state machines, and small-to-medium datapath acceleration without the NRE cost of an ASIC. The FLEX 8000 family specifically targets register-rich, low-cost, high-density applications where ICR (in-circuit reconfigurability) via external configuration devices is desired.
Key features of the EPF8452AGC160-3N include in-circuit reconfigurability, a register-rich architecture with up to 1,500 flip-flops per device family member, JTAG-compliant boundary-scan (IEEE 1149.1) support, and multi-voltage I/O capability. The 5V core supply with 5V-tolerant I/Os simplifies interfacing to legacy TTL/CMOS logic without level shifters. The CPGA-160 ceramic package is chosen for high-reliability industrial, military, and aerospace programs where plastic QFPs would not survive thermal or mechanical stress.
Architecturally, the device uses Altera's classic Look-Up Table (LUT) based logic element with a continuous routing network. The 125MHz performance rating applies to 16-bit counter / register-rich designs and reflects typical fitter output at room temperature. Configuration is loaded from an external EPROM (e.g., EPC1, EPC2) or via JTAG, with the -3N speed grade and 5V VCCIO placing it at the higher end of the FLEX 8000 performance tier.
Typical applications include industrial control and instrumentation glue logic, telecommunications interface cards, prototyping for ASIC migration, legacy Avionics and military systems requiring ceramic-package FPGAs, and telecom glue logic bridging between microprocessors and DSPs. The wide-gate-count range (4K to 16K usable gates across the family) lets designers scale up within the same toolchain (MAX+PLUS II or Quartus).
When designing with this device, account for 5V supply decoupling at the CPGA socket with at least 1uF bulk plus 0.1uF per VCC pin pair, and ensure the configuration EPROM is correctly sized for the bitstream (4K gates compresses to roughly 60-80 Kbits of configuration data). Engineers migrating legacy designs should note the FLEX 8000 family is mature and many speed/package variants are now NRND - plan obsolescence mitigation early in the lifecycle.

Ghi chú thiết kế
The EPF8452AGC160-3N requires 5V supply on all VCC pins with bulk decoupling of at least 1uF plus 0.1uF ceramic per VCC/GND pin pair. During configuration, inrush current can peak above steady-state levels; ensure the 5V regulator has adequate headroom (recommended 1A minimum). Place the EPC1 or EPC2 configuration EPROM within 6 inches of the FPGA DATA/DCLK pins to avoid signal integrity issues. After configuration completes, the FLEX 8000 enters user mode and draws steady-state current proportional to toggle rate and design density.
The ceramic CPGA-160 package must be socketed in a PGA-160 through-hole socket rated for the device mass and thermal expansion. Avoid soldering the CPGA directly to a PCB; the thermal mismatch can crack the ceramic and the package is not designed for hand rework. Provide a minimum 0.5-inch clearance around the socket for socket extraction tooling. Decoupling capacitors should be placed on the PCB side immediately adjacent to the socket, not beneath it.
Do not confuse the EPF8452AGC160-3N (ceramic CPGA-160) with the EPF8452AGC160-3 (plastic BQFP-160) - they share the same die and bitstream but have different packages and pinouts. The -3N suffix specifically denotes the ceramic Pin Grid Array package. When ordering, verify the full part number including the -3N suffix; sourcing the wrong package variant is a common production-line issue. Also note the FLEX 8000 family is NRND - plan obsolescence mitigation by qualifying a modern Cyclone or MAX 10 device as a future replacement.
Estimated: at 125MHz with 100% I/O toggle, the FLEX 8000 EPF8452 draws approximately 200-300mA, dissipating 1.0W to 1.5W. The ceramic CPGA package provides good thermal conduction to the socket and chassis; however, in enclosed instrument enclosures with limited airflow, junction temperature can rise above ambient. Apply a thermal pad between the CPGA package top and an aluminum chassis plate for heat-sinking in high-ambient-temperature applications. Operating temperature is commercial 0C to +70C only.
Thông tin tuân thủ
Ceramic CPGA-160 package is typically NOT RoHS compliant due to lead-bearing ceramic hermetic sealing. Part is NRND per Altera/Intel legacy FPGA status. AEC-Q100 not applicable for FPGAs in this family.
