EPF8820ATI144-2N 概要
A FLEX 8000 device is a class of SRAM-based programmable logic that combines fine-grained logic elements (LEs) with continuous interconnect and embedded array blocks (EABs) for memory functions. FPGAs in general sit within the programmable logic hierarchy (PLD -> CPLD -> FPGA) under the broader semiconductor category, and the FLEX 8000 family was Altera's mainstream high-density family prior to the MAX and Cyclone series. Unlike antifuse or flash FPGAs, FLEX 8000 parts are volatile and must be configured from an external EPROM or Altera serial configuration device (EPC1, EPC1213, EPC1064, EPC1441) at every power-up.
Key features include 672 logic elements, 1.7 ns combinatorial propagation delay (tPD), SRAM-based configuration that supports in-system re-programmability, an industrial operating temperature grade (-40C to +85C), and JTAG-erasable memory cells for fast design iteration. The 144-pin TQFP package uses gull-wing leads at 0.500 mm pitch for SMT assembly, and the device is pin-compatible with other EPF8820A TQ144 speed grades, allowing board reuse across the family.
Architecturally, the EPF8820A integrates logic elements organized into Logic Array Blocks (LABs), each containing multiple LEs with a 4-input look-up table, programmable register, and carry chain. EABs provide on-chip RAM/ROM with widths up to 16 bits. Continuous routing channels deliver predictable, deterministic timing well-suited to glue-logic, bus-interface, and state-machine roles in legacy industrial systems.
Typical applications include industrial machine control, legacy telecom interfaces, glue-logic replacement for TTL/74-series designs, custom bus controllers (ISA, PC/104, VME), and prototyping platforms where the FLEX 8000 toolchain (MAX+PLUS II or Quartus) is still in production use. The part is also common in long-lifecycle defense and aerospace programs where a stable 5V supply and industrial-temperature silicon are required.
When designing with this part, designers must provide an external configuration memory because FLEX 8000 devices lose their configuration on power-down. Plan a 5V analog supply with adequate decoupling (100 nF + 10 uF), respect the 4.5V to 5.5V supply window, and reserve board area for the EPC1/EPC1441 configuration EPROM. Programming is performed via the Altera ByteBlaster or via JTAG.
This page synthesizes distributor availability, Altera-family drop-in alternatives in the same TQ144 footprint, and practical design notes (configuration memory, 5V supply decoupling, JTAG chain) that are not consolidated in the manufacturer datasheet itself.

主な用途
EPF8820ATI144-2N の用途: 6 件s: Industrial Machine Control, Legacy Telecom Interface Bridging, Glue-Logic Replacement for TTL/CMOS Designs, Custom ISA / PC/104 / VME Bus Controllers, Defense / Aerospace Long-Lifecycle Systems, Prototyping Platform for Quartus / MAX+PLUS II.
Industrial Machine Control
The EPF8820ATI144-2N is a strong fit for industrial machine control because it delivers 672 logic elements in an industrial-temperature (-40C to +85C) package with deterministic 1.7 ns tPD timing. In a CNC controller, PLC, or motor-drive front-end it can replace dozens of TTL/CMOS glue-logic chips, integrating encoder interfaces, PWM generation, and safety interlocks on a single device. The 5V supply tolerance aligns directly with the 24V->5V rails common in industrial cabinets, and the TQ144 footprint gives designers enough I/O to drive stepper/direction logic and discrete inputs. Configuration via EPC1 or EPC1441 EPROM ensures the design boots reliably in factory environments with noisy power.
おすすめ
Legacy Telecom Interface Bridging
The EPF8820ATI144-2N is widely used to bridge legacy telecom interfaces such as E1/T1 framers, HDLC controllers, and PCM highway backplanes into modern CPU buses. Its 1.7 ns propagation delay handles the bit-clock and framing-edge timing required for TDM streams, and the 672 logic elements are sufficient for protocol-state machines and DMA-style FIFO glue. Industrial temperature rating makes it suitable for central-office and outside-plant enclosures, while 5V tolerance tolerates the -48V->5V isolated supplies common in telecom racks. Designers can re-target the same pinout using EPF8820ATI144-1 or EPF8820ATC144-3N for cost-down variants without PCB rework.
おすすめ
Glue-Logic Replacement for TTL/CMOS Designs
Designers migrating dense 74LS/74AS/4000-series boards to the EPF8820ATI144-2N recover board area, reduce power, and gain the ability to revise logic in software. The 672 LEs typically replace 15 to 30 equivalent SSI/MSI packages, and the predictable FLEX 8000 interconnect avoids the timing anomalies that plague multi-package TTL designs. Industrial temperature rating and 5V tolerance allow direct drop-in alongside existing 5V logic without level shifters. Use the JTAG chain for in-system re-programming during bring-up, then commit the final image to an EPC1213 or EPC1441 configuration EPROM for production.
おすすめ
Custom ISA / PC/104 / VME Bus Controllers
The EPF8820ATI144-2N is a natural fit for legacy ISA, PC/104, and VME bus controllers used in industrial PCs, test instruments, and defense electronics. With 672 LEs and abundant TQ144 I/O, it can implement bus arbiter, address decoder, interrupt controller, and custom register logic that previously required multiple PALs and FIFO chips. The 5V supply matches the ISA/PC/104 rail directly, and the industrial-temperature grade supports the extended thermal envelopes of ruggedized systems. Designers often pair the FPGA with a microcontroller or legacy CPU and use ByteBlaster JTAG for field updates.
おすすめ
Defense / Aerospace Long-Lifecycle Systems
The EPF8820ATI144-2N is qualified for long-lifecycle defense and aerospace programs because its 5V supply, industrial temperature rating, and proven FLEX 8000 architecture remain stable across decades of field deployment. Programmable logic consolidates cockpit displays, mission-computer I/O, and guidance-system interfaces that must be maintained for 20+ years. Obsolescence is mitigated by qualifying EPF8820A family variants (EPF8820ATI144-1, EPF8820ATC144-2N) that share the same TQ144 footprint and bitstream-compatible architecture, allowing lifetime buy and second-source strategies.
おすすめ
Prototyping Platform for Quartus / MAX+PLUS II
The EPF8820ATI144-2N serves as a workhorse prototyping FPGA on Altera/Intel development boards and university teaching kits where the MAX+PLUS II or Quartus design flow is still in use. With 672 LEs, 144 user I/O, and JTAG programming, students and engineers can experiment with state machines, soft-cores, and bus interfaces at low cost. The TQ144 package is hand-solderable on adapter boards, and the EPC1 configuration EPROM allows standalone demos without a host PC. The same bitstream can later be retargeted to a Cyclone or MAX device for production.

設計ノート
The EPF8820ATI144-2N requires a clean 5V supply within 4.5V to 5.5V. Place a 10 uF bulk tantalum plus 100 nF ceramic decoupling pair within 25 mm of each VCCINT/VCCIO pin group. Add a ferrite bead if the 5V rail is shared with motors or relays. Estimated: at 50 MHz toggle activity, the FLEX 8000 core draws approximately 200-400 mA; budget 1A per device on the 5V rail.
FLEX 8000 devices are SRAM-volatile - the configuration is lost at every power-down. Always include an external configuration EPROM (EPC1 for serial, EPC1064/EPC1213/EPC1441 for parallel) on the board, wired per the datasheet CONFIG block. During bring-up, allow the nCONFIG pin a clean 1 ms reset pulse; do not tie it directly to VCC or the device will not enter configuration mode reliably.
The TQ144 footprint follows JEDEC MS-026 with 0.500 mm pitch and gull-wing leads. Use a 4-layer PCB with continuous ground plane under the device to control the simultaneous-switching noise of the high-pin-count I/O bank. Keep configuration EPROM traces short (under 50 mm) and route them over a single reference plane to avoid signal-integrity issues during multi-megahertz configuration loads.
Place the JTAG header (TCK, TMS, TDI, TDO, nSTATUS, nCONFIG) on the board edge for ByteBlaster access. Reserve the JTAG pins in the Quartus/MAX+PLUS II pin planner so they are not used as user I/O. Add 10 kohm pull-ups on nCONFIG and nSTATUS to VCCIO; without these the configuration handshake can fail intermittently under noisy power-up conditions.
コンプライアンス情報
RoHS/REACH/lead-free status not stated in the verified distributor data. The -N suffix historically indicates a lead-free or Pb-free finish variant on Altera parts, but confirmation against the manufacturer declaration is recommended for new designs. AEC-Q100 is not applicable because this is an FPGA, not an automotive-grade IC.
