EPF8820ATC144-6 개요
A Field Programmable Gate Array (FPGA) is a semiconductor IC built around an array of configurable logic blocks (CLBs), programmable routing channels, and programmable I/O cells. FPGAs sit at the top of the digital logic hierarchy: programmable logic device (PLD) -> complex PLD (CPLD) -> FPGA -> SoC FPGA. The FLEX 8000 family targets glue-logic, bus-interface, and state-machine consolidation roles where discrete 74-series logic or a CPLD would otherwise consume excessive board area.
Key features include 84 Logic Array Blocks (LABs) with 8 logic elements per LAB, 4 dedicated input pins, MultiVolt I/O supporting 3.3V or 5.0V interface (144-pin packages), and configuration via industry-standard parallel EPROM or Altera serial configuration devices (EPC1, EPC1213, EPC1064, EPC1441). The -6 speed grade specifies a worst-case propagation delay of approximately 1.9ns.
The FLEX 8000 architecture uses continuous SRAM configuration memory, allowing in-system reconfiguration (ICR) via a controller or configuration device. Each LAB contains an expansion product-term array and a carry chain for arithmetic functions; interconnect uses FastTrack routing with row and column channels. Die size and process technology make this device the lowest-density FLEX 8000 variant, suitable for designs that exceed CPLD capacity but do not require modern high-logic-count FPGAs.
Typical applications include bus-interface bridging (PCI, ISA, VME), glue-logic consolidation in industrial controllers, state-machine replacement, address decoding and interrupt handling in embedded systems, and legacy 5V peripheral interfacing where MultiVolt I/O removes the need for level shifters. Production-intent designs targeting this part typically migrate to newer Cyclone or MAX families today.
Design considerations include dedicated VCCINT and VCCIO rail separation for 3.3V/5.0V I/O, mandatory configuration device selection (EPC1, EPC2, EPC1441), and JTAG support via nCONFIG, nSTATUS, and CONF_DONE pins. The -6 speed grade represents one of the slower grades in the family; faster -3 or -2 grades are usable when timing margins are tight.

일반적인 애플리케이션
EPF8820ATC144-6 적합 용도: 6 애플리케이션s: PCI / ISA Bus Interface Bridging, Industrial Glue-Logic Consolidation, Address Decoding and Interrupt Handling, Legacy 5V Peripheral Interfacing, State-Machine Replacement in Embedded Controllers, VME Bus Interface in Legacy Industrial Systems.
PCI / ISA Bus Interface Bridging
The EPF8820ATC144-6's 112 user I/Os and 5V-tolerant MultiVolt interface make it well suited for PCI and ISA bus bridging in legacy industrial PCs. Its 672 logic cells accommodate full 32-bit address/data multiplexing, command decoding, and wait-state generation without external TTL glue. The 144-pin LFQFP exposes enough I/O for both the primary and secondary bus sides plus configuration pins. The -6 speed grade is acceptable for 33MHz PCI and full-speed ISA, where 1.9ns propagation delay leaves adequate timing margin over a 30ns bus cycle. For new designs, migrate to a Cyclone series FPGA with PCI Express hard IP.
추천
Industrial Glue-Logic Consolidation
The EPF8820ATC144-6 consolidates dozens of 74-series logic packages into a single 144-pin LFQFP, saving substantial PCB area in industrial controllers and PLCs. Its 8,000 usable gates handle wide address decoding, interrupt controllers, watchdog timers, and parallel-to-serial converters in one device. The 5V VCCINT plus MultiVolt I/O (3.3V or 5.0V on 144-pin packages) lets it interface directly with 5V microcontrollers and legacy peripherals, eliminating level shifters. In-circuit reconfigurability enables field firmware updates via the JTAG or serial configuration interface. Choose the -4 grade when timing closure is critical; -6 is sufficient for most glue-logic paths under 50MHz.
추천
Address Decoding and Interrupt Handling
The EPF8820ATC144-6 is well suited for memory and peripheral address decoding plus interrupt prioritization in 16/32-bit embedded systems. Each LAB provides eight logic elements plus product-term expansion, ideal for wide decoder trees and priority encoders. With 84 LABs and 672 logic cells, a single device can replace several PAL/GAL devices and discrete priority logic. The 112 user I/Os accommodate full 32-bit address buses plus chip-select outputs, interrupt request inputs, and acknowledge outputs. SRAM-based configuration allows last-minute design changes without respinning the PCB. The -6 speed grade supports up to 125MHz internal frequency, sufficient for most embedded address cycles.
추천
Legacy 5V Peripheral Interfacing
The EPF8820ATC144-6's MultiVolt I/O on the 144-pin LFQFP package supports direct 3.3V and 5.0V interfacing without external level shifters, simplifying designs that must bridge modern 3.3V ASICs to legacy 5V peripherals. Its 112 I/Os accept TTL/CMOS thresholds on a per-pin basis via VCCIO banks, allowing mixed-voltage signals on the same device. The 672-cell capacity handles UARTs, FIFOs, and parallel-port glue logic in a single chip. In-circuit reconfigurability (ICR) lets designers iterate on protocol logic without board changes. For new designs targeting 3.3V-only systems, migrate to a Cyclone III or later FPGA with similar density at lower power.
추천
State-Machine Replacement in Embedded Controllers
The EPF8820ATC144-6's 672 logic cells and 8K usable gates are ideal for implementing complex state machines that would otherwise require multiple PAL/GAL devices. Each Logic Element includes a 4-input LUT, register, and carry chain, supporting Moore and Mealy state machines with up to hundreds of states. The 125MHz internal frequency allows state-machine operation well above typical microcontrollers, and the 144-pin LFQFP exposes enough I/O for 32-bit datapath glue plus dedicated inputs. JTAG-based configuration and in-system reconfigurability let engineers iterate on state-machine logic during development. The -6 speed grade is acceptable for state machines with sub-50MHz clock rates.
추천
VME Bus Interface in Legacy Industrial Systems
The EPF8820ATC144-6 is well matched to VMEbus interface cards in legacy industrial and test-and-measurement equipment. Its 112 user I/Os comfortably handle the VME 32-bit address/data bus, arbitration lines, and interrupt request/acknowledge signals. MultiVolt I/O on the 144-pin package interfaces directly to 5V VME transceivers without external buffers. The 672-cell capacity accommodates full bus-master arbitration, address pipelining, and block-transfer handshaking in one device. SRAM configuration supports last-minute firmware updates in the field. For new VME64 designs, consider migrating to a larger FLEX 8000 device (EPF81188A or EPF81500A) with higher I/O count.

설계 노트
Separate VCCINT (5V core) and VCCIO (3.3V or 5.0V I/O bank supplies) with adequate decoupling - place 0.1uF ceramic capacitors near every VCCINT and VCCIO pin, plus bulk 10-47uF tantalum or ceramic at each supply rail. The MultiVolt I/O feature on 144-pin packages lets you mix 3.3V and 5.0V signaling on different banks without level shifters - consult the FLEX 8000 datasheet for the exact bank assignments.
Configuration data is volatile - SRAM-based FLEX 8000 devices must be configured at every power-up. Always include an Altera EPC1, EPC2, EPC1213, EPC1064, or EPC1441 serial configuration device (or equivalent parallel EPROM/controller) on the board. Failure to provide a configuration source leaves the device in undefined state with all I/Os tri-stated. For JTAG-based configuration, ensure TCK/TMS/TDI/TDO are properly pulled and the JTAG chain is correctly ordered with any other JTAG devices on the board.
The 144-pin TQFP (LFQFP) requires careful PCB layout with 0.5mm pitch traces. Use 4-layer board with continuous ground plane beneath the device for signal integrity and power distribution. Place configuration device (EPC1441) within 50mm of the FPGA to keep DCLK/Data traces short. Route JTAG signals to a header with the correct pinout for Altera ByteBlaster or USB-Blaster download cables.
MultiVolt I/O banks can mix 3.3V and 5.0V signals on the same device, but each bank's VCCIO must be tied to a single voltage. Do not mix voltages within one bank or you risk input-clamping currents and long-term reliability issues. For high-speed outputs (>50MHz), use 5V-tolerant receivers rated for the slower edge rates typical of 5V CMOS. For inputs from 3.3V devices into 5V VCCIO banks, ensure the 3.3V logic-high VIH is above the 5V bank's threshold.
FLEX 8000 devices use 5V core supply which generates substantial heat compared to modern 1.2V FPGAs. At full toggle activity across all 112 I/Os, expect junction temperature to rise significantly. Provide adequate copper pour around the 144-pin TQFP - at least 1 square inch of 2oz copper on top and bottom layers connected via thermal vias. For sealed enclosures or stacked boards, verify theta_JA against the FLEX 8000 datasheet and derate ambient temperature accordingly.
