EPF8820ATC144-1 - FLEX 8000 FPGA, 672 Cells, 112 I/O, 144-TQFP | Altera
MPN: EPF8820ATC144-1 ✗ Cuối đờiEPF8820ATC144-1 Tóm tắt
An FPGA (Field Programmable Gate Array) is a type of integrated circuit containing an array of programmable logic blocks, interconnect resources, and configurable I/O cells that engineers can customize after manufacture. FPGAs sit between fixed-function ASICs and CPLDs in the programmable logic hierarchy, offering higher logic density than CPLDs while remaining factory-reprogrammable. The FLEX 8000 family is configured at system power-up from an industry-standard parallel EPROM, an Altera serial configuration device (EPC1, EPC1064, EPC1213, or EPC1441), or a system controller, and supports MultiVolt I/O for interfacing with 3.3V or 5.0V logic rails.
Key features include in-circuit reconfigurability (ICR) via external configuration devices, MultiVolt I/O pin operation, a built-in Joint Test Action Group (JTAG) boundary-scan test interface per IEEE Std. 1149.1, and global routing resources for clock and control distribution. The EPF8820ATC144-1 is fabricated on a 5V CMOS process with SRAM configuration memory and is specified for the commercial operating temperature range of 0C to 70C.
Typical applications include glue logic replacement, custom state-machine controllers, bus-interface bridging, and peripheral emulation in industrial control, telecom, and embedded computing systems. The FLEX 8000 architecture is register-rich, with the EPF8820A device providing up to 1,500 flip-flops, making it well-suited to pipelined datapath and small processor glue-logic roles.
When designing with this device, ensure that the configuration scheme is selected and validated before PCB fabrication because FLEX 8000 devices are SRAM-based and lose configuration when power is removed. Plan for a non-volatile configuration memory on the board, and verify that JTAG chain ordering, voltage-level translation, and decoupling are sized for the 5V supply rail. For new designs consider Cyclone IV or Cyclone V as modern, lower-power successors.

Ứng dụng tiêu biểu
EPF8820ATC144-1 phù hợp cho 7 Áp dụngs: Glue Logic Replacement, Custom State-Machine Controllers, Bus-Interface Bridging, Peripheral Emulation, Embedded Computing Subsystems, Legacy Telecom Datapath, Test & Measurement Front-End.
Glue Logic Replacement
The EPF8820ATC144-1's 672 logic cells, 84 LABs, and 112 user I/Os are well-matched to consolidating scattered discrete TTL/CMOS glue logic on legacy boards. With up to 1,500 flip-flops available, the part can replace dozens of 74-series packages while preserving the 5V supply and parallel-EPROM configuration flow familiar to FLEX 8000 designs. Unlike an ASIC, the device is in-circuit reconfigurable (ICR), allowing post-layout bug fixes without board rework.
Được đề xuất
Custom State-Machine Controllers
The FLEX 8000 register-rich architecture gives the EPF8820ATC144-1 the flip-flop density required for complex finite state machines used in industrial control, telecom, and instrumentation. Designers can encode wide state vectors, large microsequencers, and bit-serial protocols across the 1,500 available flip-flops. The 144-pin TQFP exposes enough I/O for parallel sensor buses and discrete control lines while keeping the board on a 5V rail.
Được đề xuất
Bus-Interface Bridging
Bridging between legacy 5V buses (ISA, PC/104, VME, parallel peripheral) and downstream 3.3V devices is straightforward with the EPF8820ATC144-1 thanks to its MultiVolt I/O feature. Each I/O bank can be set independently for 3.3V or 5.0V operation, allowing level translation and protocol conversion in a single chip. The 112 user I/Os provide generous headroom for parallel address/data/control bridging without external buffers.
Được đề xuất
Peripheral Emulation
The EPF8820ATC144-1 is widely used to emulate obsolete peripheral controllers, custom ASICs, and legacy video or DMA engines in long-lifecycle industrial systems. Its SRAM-based configuration allows the emulation bitstream to be updated as the host system evolves, while the JTAG (IEEE 1149.1) interface simplifies bench bring-up and field diagnostics. Designers can replace a discontinued IC with the same board footprint while preserving original software behavior.
Được đề xuất
Embedded Computing Subsystems
In embedded designs, the EPF8820ATC144-1 serves as a coprocessor or peripheral controller alongside a microprocessor or microcontroller. Its 672 logic cells support small RISC cores, DMA engines, and custom interrupt controllers, while 112 I/Os expose the address/data buses needed for tight CPU coupling. The 5V supply and 144-pin TQFP keep it compatible with legacy MCU/DSP baseboards.
Được đề xuất
Legacy Telecom Datapath
Datapath and framing functions in legacy telecom line cards and base-station controllers fit naturally into the EPF8820ATC144-1's register-rich architecture. Bit-serial protocols, framing/deframing, HDLC controllers, and small CRC engines map efficiently to the FLEX 8000 LAB structure, and the 112 I/Os handle parallel PCM/TDM buses. Designers can hold 5V system power while gaining a programmable replacement for obsolete ASICs.
Được đề xuất
Test & Measurement Front-End
The EPF8820ATC144-1's MultiVolt I/O and 112 user I/Os suit it to custom test and measurement front-ends where mixed-voltage analog-to-digital converters and parallel display buses must be sequenced and timed. The 1,500-flip-flop headroom supports custom trigger logic, counters, and timing generators that would otherwise require multiple discrete PLDs. JTAG access speeds bench bring-up and in-field firmware updates.

Ghi chú thiết kế
The EPF8820ATC144-1 requires a stable 5.0V VCCINT (core) supply and per-bank VCCIO supplies that can be set independently for 3.3V or 5.0V operation. Place 0.1uF decoupling capacitors as close as possible to every VCCINT and VCCIO pin, and add bulk 10uF-47uF tantalum or ceramic capacitors near each supply pin. Power-up sequencing must satisfy the FLEX 8000 requirements: VCCINT and VCCIO must ramp monotonically to ensure proper configuration.
FLEX 8000 devices are SRAM-based and lose their configuration when power is removed. A non-volatile configuration source (EPC1, EPC1064, EPC1213, EPC1441, or parallel EPROM) is required for production boards. The nCONFIG, nSTATUS, and CONF_DONE pins must be pulled and monitored per the datasheet; failing to do so results in configuration failure at power-up. During JTAG programming, ensure the JTAG chain order matches the BSDL file before asserting nCONFIG.
Route configuration and JTAG signals (TCK, TMS, TDI, TDO, nCONFIG, nSTATUS, CONF_DONE, MSEL, DCLK, DATA[0..7]) away from fast-switching user I/O to avoid coupling into the configuration logic. Keep global clock pins short and guarded by ground on both sides. Because the 144-pin TQFP has 0.5 mm pitch, use 0.15 mm/0.20 mm trace-and-space rules and verify the PCB vendor supports fine-line manufacturing.
MultiVolt I/O allows each bank to operate at 3.3V or 5.0V but level translation is only between VCCIO and the FPGA core - never between banks with different VCCIO unless a level-shifting buffer is added. When mixing 3.3V and 5.0V peripherals, place 5V-tolerant buffers on 3.3V outputs that drive 5V inputs to prevent leakage. Use IBIS simulation to validate edge rates on parallel buses that exceed 50 MHz.
Thông tin tuân thủ
The EPF8820ATC144-1 (without "N" suffix) is the original Pb-bearing finish; "N" suffix variants (e.g. EPF8820ATC144-4N) are lead-free and RoHS-compliant. Confirm the exact finish by the date code and supplier paperwork before use in RoHS-restricted builds.
