EPF8820ATC144-11 Обзор

The Intel (formerly Altera) EPF8820ATC144-11 is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays, integrating 8,000 usable gates and 672 logic cells in a 144-pin TQFP (Plastic Thin Quad Flat Pack) package. Speed grade -11 indicates a specific propagation-delay bin, with the wider FLEX 8000 family operating up to 125 MHz internally and supporting 112 user I/O in this TQFP-144 form factor. Supply voltage is 5.0 V nominal with MultiVolt I/O capability (3.3 V or 5.0 V tolerance).

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.

This page synthesizes distributor stock, drop-in Altera/Intel alternatives, and configuration-design guidance beyond the bare datasheet — covering compatibility with the FLEX 8000 family lineup and modern supply-chain alternatives.

Типичное применение

EPF8820ATC144-11 подходит для 6 применениеs: 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.

🏭

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.

🌐

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.

🔧

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.

✈️

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.

🎓

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.

Is the EPF8820ATC144-11 in stock?
Stock availability for the EPF8820ATC144-11 fluctuates because the FLEX 8000 family has been obsolete since the early 2000s. As of 2026-09-12, DigiKey and Mouser do not stock it directly; availability comes through broker channels (Pacific Corporation, Ande Electronics, Shenzhen WTX Capacitor) with limited lot sizes. Check backorder status with the seller before placing production orders.
EPF8820ATC144-11 vs EPF8820ATC144-10 — which should I pick?
The EPF8820ATC144-11 and EPF8820ATC144-10 are pin-compatible FLEX 8000 family variants differing only in speed grade. The -11 grade is slightly faster (lower propagation delay) than the -10; both share the same 144-TQFP package and identical functional behavior. According to the FLEX 8000 datasheet, the speed-grade digit denotes the timing bin, so substitute freely if the design meets the slower grade.
Can the EPF8820ATC144-4 replace the EPF8820ATC144-11?
Yes — the EPF8820ATC144-4 is a same-package (144-TQFP) drop-in replacement for the EPF8820ATC144-11 within the FLEX 8000 family, differing only in speed grade. According to the FLEX 8000 datasheet, -4 indicates a different timing bin (slightly slower than -11 in this family), so confirm timing margin in time-critical paths. Both parts share the same 8K gates, 672 cells, 112 I/O, and 5 V MultiVolt I/O.
When should I choose the EPF8820ATC144-11 over a modern Cyclone FPGA?
Choose the EPF8820ATC144-11 only when maintaining a legacy 5 V design where redesign for a 3.3 V Cyclone device would be cost-prohibitive, or when exact FLEX 8000 silicon behaviour is required for backward compatibility. According to the FLEX 8000 datasheet, the EPF8820A supports MultiVolt I/O for mixed 3.3 V / 5 V rails. For new designs, a modern Cyclone IV/V or MAX V CPLD offers lower cost and active lifecycle support.
What are the key specifications of the EPF8820ATC144-11 that engineers should know?
According to the Altera FLEX 8000 datasheet, the EPF8820ATC144-11 integrates 8,000 usable gates, 672 logic cells, and 112 user I/O in a 144-pin TQFP package. Core voltage is 5.0 V nominal with MultiVolt I/O support for 3.3 V or 5.0 V rails; internal operation reaches 125 MHz on a 0.42 µm CMOS SRAM process. Configuration is via EPC1/EPC1213/EPC1064/EPC1441 EPROMs or JTAG.
Where can I download the EPF8820ATC144-11 datasheet PDF?
The EPF8820ATC144-11 datasheet is available as part of the Altera FLEX 8000 family datasheet on the Intel FPGA documentation archive. According to fpgakey.com and Alterasemi.com listings, the family datasheet covers all speed grades (-3/-4/-10/-11) and packages; the document was published in 1994 with subsequent revisions. Search the Altera FLEX 8000 datasheet folder on the Intel support site for the full PDF.

Руководство по выбору

Choose the EPF8820ATC144-11 when you must maintain a legacy 5 V FLEX 8000 design where the existing 144-pin TQFP footprint, 112 I/O budget, and 8K-gate logic capacity are already qualified — typically industrial PLC backplanes, legacy telecom backplanes, or MIL-STD-1553 interface boards. For new designs or where timing closure is not critical, prefer the slower but more available EPF8820ATC144-4 (also obsolete but better broker stock). If you can change the PCB, consider the FLEX 10K family (EPF10K10, EPF10K20) or modern Cyclone IV/V devices for active lifecycle support. EPF8820ATC144-11 is appropriate only when the original FLEX 8000 silicon behavior is mandatory and a faster speed grade than -10 is required.

Заметки по проектированию

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.
