A Field Programmable Gate Array (FPGA) is a programmable logic device (PLD) whose logic and interconnections are configured by CMOS SRAM cells, distinguishing it from CPLDs (which use non-volatile fuses or flash) and ASICs (custom-masked). Architecturally, an FPGA sits between a CPLD and a hard-masked ASIC in the programmable-logic taxonomy, and within the FLEX 8000 family it provides higher register counts than the smaller EPF8282A and lower density than the EPF81188A / EPF81500A. The FLEX 8000 family uses a fine-grained, register-rich architecture optimized for register-intensive datapaths and in-circuit reconfigurability.
Key features of the EPF8820ATC144-11 include: 8,000 usable gates, 672 logic cells, 112 user I/O pins, 125 MHz internal operation, 0.42 µm CMOS SRAM process, MultiVolt I/O interface, in-circuit reconfigurability (ICR) via external serial/parallel EPROM or Altera EPC1/EPC1213/EPC1064/EPC1441 configuration devices, JTAG boundary-scan support, and a commercial operating temperature range of 0 °C to 70 °C. The 144-pin TQFP package measures 20 mm × 20 mm with 0.5 mm pitch.
The FLEX 8000 architecture is built from Logic Array Blocks (LABs) interconnected by a continuous FastTrack interconnect. Each LAB contains multiple Logic Elements (LEs) — the basic building blocks comprising a 4-input look-up table, a programmable register, and a carry chain for arithmetic. This register-rich architecture makes FLEX 8000 well-suited to state machines, datapath controllers, and bus-interface glue logic rather than purely combinational designs.
Typical applications include glue-logic integration on legacy 5 V ISA/PCI motherboards, industrial control PLCs, telecommunications backplane glue logic, prototyping for ASIC migration, military/aerospace legacy systems, and educational FPGA development platforms. The MultiVolt I/O allows direct interfacing with both 3.3 V and 5.0 V devices without level shifters.
When designing with this device, ensure the chosen configuration device (EPC1, EPC1213, EPC1064, or EPC1441) matches the bitstream size. JTAG programming requires the TCK/TMS/TDO/TDI pins to be pulled correctly and a BSDL file from the FLEX 8000 family datasheet.

典型應用
EPF8820ATC144-11 適用於 6 應用s: Legacy 5 V ISA/PCI Motherboard Glue Logic, Industrial PLC Logic Controller, Telecommunications Backplane Glue Logic, ASIC Prototyping and Emulation, Military / Aerospace Legacy Avionics, Educational FPGA Development Platform.
Legacy 5 V ISA/PCI Motherboard Glue Logic
The EPF8820ATC144-11 is well-suited to legacy 5 V ISA and PCI motherboard glue logic where it integrates scattered 74-series glue into a single programmable device. With 8,000 usable gates and 672 logic cells it absorbs address decoding, wait-state generation, and bus arbitration that previously required dozens of discrete TTL chips. The MultiVolt I/O allows direct connection to 5 V ISA slots and 3.3 V peripherals without level shifters, while 112 user I/O pins give enough headroom for full 16-bit and 32-bit bus interfaces plus interrupt steering.
推薦
Industrial PLC Logic Controller
In industrial PLC and process-control applications, the EPF8820ATC144-11 replaces discrete relay-logic boards with a single reprogrammable logic module that handles I/O scanning, latching, and timing. The 0 to 70 °C commercial operating range covers most factory-floor enclosures, while 8K gates accommodate ladder-logic translation for several hundred I/O points. The 144-pin TQFP footprint allows direct PCB replacement of older PLD sockets, and in-circuit reconfigurability permits remote firmware updates via JTAG or configuration EPROM swap during commissioning.
推薦
Telecommunications Backplane Glue Logic
The EPF8820ATC144-11 serves as backplane glue logic in telecom equipment, integrating bus arbitrators, interrupt controllers, and timing circuits between line cards and a central controller. With MultiVolt I/O, it interfaces both 3.3 V ASICs and 5 V bus transceivers on the same backplane, while 125 MHz internal operation supports T1/E1 framing and HDLC controllers. The 144-TQFP package is compatible with the pin pitch of legacy telecom backplanes, making it a drop-in for previous-generation Altera designs that require a one-speed-grade upgrade.
推薦
ASIC Prototyping and Emulation
The EPF8820ATC144-11 is widely used as an ASIC prototyping vehicle because its register-rich FLEX 8000 architecture maps cleanly from RTL descriptions, and 8,000 gates supports most glue-logic ASICs. Engineers can iterate on register-transfer-level designs in-system and burn the final mask-ROM ASIC once stable. With 672 logic cells and fast carry chains, the EPF8820ATC144-11 fits a typical 32-bit datapath plus state-machine controller, while JTAG allows post-layout verification against the original ASIC netlist via boundary scan.
推薦
Military / Aerospace Legacy Avionics
Defense and aerospace programs with decades-long lifecycles still maintain EPF8820ATC144-11 in fielded avionics, where the part's documented MultiVolt I/O and 0 to 70 °C operating range suit pressurized avionics bays. With 112 user I/O, the FPGA integrates multiple MIL-STD-1553 transceivers, ARINC 429 channels, and discrete I/O conditioning into a single part. The 144-pin TQFP is hermetically socket-compatible with legacy board layouts, and Altera-original silicon (now Intel) is preferred for counterfeit-resistant long-term support.
推薦
Educational FPGA Development Platform
Universities and technical colleges continue to use EPF8820ATC144-11 on legacy Altera-developed FPGA training boards because the FLEX 8000 family is well-documented and the Altera MAX+PLUS II design software is freely available. With 672 logic cells, students can implement a full RISC CPU core, UART, and VGA controller on the 144-pin TQFP board. MultiVolt I/O simplifies interfacing to 5 V prototyping peripherals, while 125 MHz operation lets students explore pipeline and timing-closure concepts before moving to modern Cyclone or Stratix FPGAs.

主要差異化特點
- Speed grade -11 in the 144-TQFP package (對比EPF8820ATC144-4)
- Largest plastic TQFP package for the EPF8820A device (對比EPF8820ATC100-2)
- MultiVolt I/O for mixed-voltage designs (對比EPF8282ATC100-4)
設計說明
Estimated: at 5.0 V core with 100 MHz operation across 672 logic cells at 100% toggle, the EPF8820ATC144-11 draws roughly 200-300 mA (about 1.0-1.5 W). Use a 4-layer PCB with a dedicated VCCINT plane and at least four 0.1 µF ceramic decoupling capacitors placed within 5 mm of each VCCINT pin group. Bulk tantalum or polymer capacitors (33-100 µF) on each VCCIO bank reduce switching-noise coupling into analog rails.
A common pitfall when bringing up the EPF8820ATC144-11 is forgetting to hold nCONFIG low during power-up ramp — the device will not enter configuration mode and CONF_DONE stays low. According to the Altera FLEX 8000 datasheet, nCONFIG must be held low until VCCINT reaches 4.75 V minimum, then released. Similarly, pull-ups (10 kΩ) on nSTATUS and CONF_DONE are mandatory since these are open-drain outputs.
The 144-pin TQFP has a 0.5 mm lead pitch, which is the densest Altera FLEX 8000 plastic package. Per the FLEX 8000 datasheet, escape routing on a 4-layer PCB requires 0.15 mm/0.20 mm trace/spacing rules with via-in-pad recommended only on inner rows. Place JTAG chain components (TCK pull-down, TDI/TMS pull-ups) within 25 mm of the device to avoid signal-integrity issues at JTAG TCK frequencies above 10 MHz.
Estimated: configuration bitstream for the EPF8820ATC144-11 (672 cells, 8K gates) is approximately 95-120 Kbit. The Altera EPC1 (1 Mbit) and EPC1441 (440.8 Kbit) configuration EPROMs are the closest matches. According to the FLEX 8000 datasheet, select MSEL0/MSEL1 mode-strapping pins to choose between serial (EPC1/EPC1441) and parallel (EPC1064/EPC1213) modes. Verify the bitstream CRC against the Quartus/MAX+PLUS II .hex output before programming production EPROMs.
