MPN: EPF8820AQC160-2 ✗ Cuối đờiEPF8820AQC160-2 Tóm tắt
An FPGA (Field Programmable Gate Array) is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all of which can be reconfigured after manufacture. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs) between simple CPLDs and high-density SoC FPGAs, and they are widely used for digital logic prototyping, custom interface bridging, and small-volume hardware acceleration where ASIC NRE costs are prohibitive. The FLEX 8000 series pioneered in-circuit reconfigurability (ICR) via an external serial or parallel configuration EPROM, allowing field updates without removing the device from the board.
Key features of the EPF8820AQC160-2 include 120 user I/O pins supporting 5 V PCI-compliant signaling, a built-in JTAG (IEEE 1149.1) boundary-scan test interface, and a hierarchical interconnect architecture that routes signals between logic elements through fast local and global routing resources. The device supports both synchronous and asynchronous design styles, and its rich register count (approximately 712 flip-flops across the 672 logic elements) makes it well suited to pipelined datapaths and control logic with significant state-holding requirements.
From a technical perspective, the FLEX 8000 architecture implements each logic element as a 4-input look-up table (LUT) feeding a programmable register, with carry-chain support for fast arithmetic. The SRAM configuration memory means the device is volatile and must be loaded at power-up, typically from a serial configuration PROM such as the EPC1 or EPC2. The -2 speed grade indicates a mid-tier timing closure suitable for most commercial designs at clock rates up to 125 MHz.
Typical applications include PCI bus interface bridges, custom peripheral controllers for legacy microprocessors, glue logic replacing multiple 74-series TTL devices, industrial control boards with moderate logic density, and telecommunications line-card interface logic. The 160-pin PQFP package is easy to hand-prototype and rework, making the EPF8820AQC160-2 a popular choice for low-volume production and engineering development platforms.
When designing with this device, ensure the configuration memory solution (EPC1/EPC2 or compatible) is correctly wired to the dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0). Because the configuration is SRAM-based, plan for deterministic power-up behavior, and add JTAG boundary-scan to simplify board test.

Ứng dụng tiêu biểu
EPF8820AQC160-2 phù hợp cho 6 Áp dụngs: PCI Bus Interface Bridge, Glue Logic Replacement (74-series Consolidation), Industrial Control Board Logic, Telecommunications Line-Card Interface, Legacy Microprocessor Peripheral Glue, Engineering Education and FPGA Architecture Studies.
PCI Bus Interface Bridge
The EPF8820AQC160-2 is well suited for PCI bus interface bridging in legacy add-in cards and embedded motherboards. Its 120 user I/Os comfortably accommodate the 32-bit, 33 MHz PCI bus (49 signals) plus glue logic for address decoding, command handling, and interrupt steering, with headroom remaining for application-specific registers and FIFOs. The 5 V PCI signaling standard matches the FLEX 8000 I/O supply directly, eliminating level shifters. The 672 logic cells provide ample capacity for target/initiator state machines, configuration-space registers, and bus-master DMA engines. Compared with discrete 74-series logic, a single EPF8820AQC160-2 replaces dozens of packages, reducing PCB area and improving signal integrity by shortening interconnect.

Glue Logic Replacement (74-series Consolidation)
Many legacy designs use clusters of 74FCT, 74ABT, or 74ACT TTL packages for address decoding, bus multiplexing, and register-based control. The EPF8820AQC160-2 can absorb 20-40 such packages into a single 160-PQFP device, freeing substantial board area and reducing BOM count. Its 5 V tolerant I/Os interface directly with existing TTL logic without level translation, and the SRAM-based configuration permits last-minute design changes during prototyping. The -2 speed grade delivers sub-10 ns combinatorial delays, matching the propagation time of multiple cascaded TTL gates, making timing closure transparent for typical glue-logic tasks.
Được đề xuất
Industrial Control Board Logic
Factory automation controllers often require custom logic for sensor conditioning, motor-step pulse generation, encoder quadrature decoding, and safety-interlock handling. The EPF8820AQC160-2 fits these tasks with its 120 I/Os accepting 5 V sensor signals directly, and 672 logic cells supporting multiple state machines in parallel. Commercial temperature grade (0 °C to 70 °C) suits cabinet-mounted equipment, while the PQFP package withstands industrial vibration when properly socketed or potted. The JTAG boundary scan simplifies factory board test, catching solder defects and wiring errors before deployment.
Được đề xuất
Telecommunications Line-Card Interface
TDM (Time Division Multiplexing) line cards in legacy telecom infrastructure use FPGAs for HDB3/AMI encoding, framing, alarm extraction, and switch-matrix control. The EPF8820AQC160-2's 125 MHz toggle rate accommodates E1 (2.048 MHz) and T1 (1.544 MHz) bit-rate designs with ample timing margin, while the 120 I/Os handle multiple E1/T1 ports in parallel plus backplane interfaces. Its 5 V supply matches the -48 V telecom bus-derived rails used in central-office line cards. The in-circuit reconfigurability permits remote firmware updates, valuable for installed-base service.
Được đề xuất
Legacy Microprocessor Peripheral Glue
Embedded systems based on Intel 80x86, Motorola 68k, or older ARM processors often need custom peripherals such as interrupt controllers, DMA engines, memory-mapping logic, and watchdog timers. The EPF8820AQC160-2 can implement all of these in a single device, with its 672 cells and 120 I/Os accommodating 4-6 peripheral functions concurrently. The 5 V I/O bank interfaces directly with classic microprocessor buses, and the JTAG interface allows in-system debugging of soft-core peripherals during development.
Được đề xuất
Engineering Education and FPGA Architecture Studies
Universities teaching digital design and FPGA architecture often use legacy Altera/Intel FPGAs because of their well-documented architectures and abundant reference designs. The EPF8820AQC160-2's 672-cell capacity is large enough for meaningful designs (UART, VGA controller, simple CPU) yet small enough to fit within student lab budgets. The 160-PQFP package is large enough to probe with oscilloscope hooks, and JTAG-based configuration via a ByteBlaster or USB-Blaster cable provides hands-on programming experience that aligns with industry-standard FPGA toolchains.

Ghi chú thiết kế
The EPF8820AQC160-2 requires a clean 5 V supply on VCCINT and VCCIO pins (separated internally). Decouple each VCC pin with a 0.1 µF ceramic capacitor placed within 5 mm of the package, plus a bulk 10-47 µF tantalum or polymer capacitor on the board. During configuration, the device draws brief inrush current up to several hundred mA; size the regulator accordingly. SRAM-based configuration is volatile — the device must be reconfigured after every power-up.
PQFP-160 packages with 0.65 mm pitch require PCB pad design following IPC-7351 guidelines with a slightly shorter pad length to prevent solder bridging. Use a reflow profile with peak temperature below 240 °C and time-above-liquidus under 60 seconds to avoid package delamination. For hand-prototyping or rework, use a fine-tip soldering iron and no-clean flux with low residue.
Place the EPC1 or EPC2 configuration PROM within 50 mm of the EPF8820AQC160-2 to keep DCLK and DATA0 traces short and matched (within 10 mm). Add a 1 kΩ pull-up resistor on nCONFIG and a 1 kΩ pull-down on nSTATUS to ensure deterministic configuration startup. Use a dedicated ground plane under the FPGA and PROM to reduce switching-noise coupling into configuration signals.
Common pitfalls include: (1) failing to provide the JTAG chain termination resistors on TMS and TCK, causing intermittent configuration failures; (2) tying CONF_DONE low before power-up, preventing configuration; (3) leaving unused I/O pins floating — these should be set to outputs driving ground or configured as inputs with internal pull-ups to avoid mid-rail oscillation that draws supply current; (4) forgetting that nCONFIG must be toggled low-then-high to reconfigure the device.
