EPF8820ATC144-15 概要
A Field Programmable Gate Array (FPGA) is a semiconductor device whose logic and interconnections are configured by the user via SRAM configuration memory, placing FPGAs in the broader hierarchy of programmable logic devices (PLDs) -> FPGAs -> CMOS programmable logic. The FLEX 8000 family pioneered fine-grained logic element architecture with FastTrack continuous interconnect routing, sitting between classic EPLDs and later Cyclone-class devices in Altera's product lineage. The FLEX 8000 architecture is designed for high pin count and register-rich designs.
Key features of the EPF8820ATC144-15 include in-system reconfigurability via serial or parallel configuration devices (EPC1, EPC1064, EPC1213, EPC1441), JTAG support via the IEEE 1149.1 boundary-scan interface, and MultiVolt I/O for mixed-voltage system integration. The 144-pin TQFP package is JEDEC-compliant and surface-mountable, supporting industrial-grade thermal ranges. The CMOS SRAM technology provides low static power and unlimited re-programmability, in-circuit reconfigurability (ICR) being a hallmark of the FLEX 8000 family.
Architecturally, the EPF8820ATC144-15 implements 672 logic elements arranged into Logic Array Blocks (LABs), each LAB containing eight LEs with a local interconnect. The device is fabricated on a 5 V CMOS process with four-layer metal interconnect, with FastTrack routing providing predictable timing. Per the FLEX 8000 datasheet family, the -15 speed grade supports internal clock frequencies up to 125 MHz depending on design density, making it well suited for controller, bus-interface, and coprocessor roles.
Typical applications include bus-interface bridging (e.g., between 5 V and 3.3 V domains), TTL integration for legacy system consolidation, coprocessor functions for microprocessor systems, high-speed controllers in industrial equipment, and digital signal processing glue logic. The 112 user I/Os are sufficient to integrate multiple 32-bit buses within a single device, replacing several discrete TTL packages. Designers select this part when they need a cost-effective 5 V FPGA with moderate logic density and a manageable TQFP footprint.
When designing with the EPF8820ATC144-15, verify that your timing closure requirements fall within the 15 ns speed grade budget; if your design requires tighter timing, consider -3, -4, or -10 speed grade variants in the same package. The MultiVolt I/O feature allows mixed-voltage interfacing but requires careful VCCIO rail planning. Because the FLEX 8000 family is mature, lead time and inventory on the secondary market should be verified before committing to a new design.

主な用途
EPF8820ATC144-15 の用途: 6 件s: Bus Interface Bridging, TTL Integration / Glue Logic Consolidation, Microprocessor Coprocessor Functions, High-Speed Industrial Controllers, Legacy System Replacement, DSP Pre/Post-Processing Glue Logic.
Bus Interface Bridging
The EPF8820ATC144-15 is well suited to bridge between 5 V and 3.3 V bus domains thanks to its MultiVolt I/O feature and 112 user I/Os. With 8,000 usable gates and 672 logic elements, the device can implement multi-byte bus transceivers, FIFO buffers, and protocol converters in a single chip. The 144-pin TQFP package exposes enough I/O to integrate multiple 32-bit buses simultaneously, replacing several discrete 74-series TTL packages and saving board area. The 15 ns tpd comfortably supports typical bus speeds up to approximately 25-30 MHz, covering most legacy parallel bus standards. Designers place the FPGA between the two bus domains with VCCIO tied to the lower-voltage rail, and use the configurable I/O standards for direction control.
おすすめ
TTL Integration / Glue Logic Consolidation
Designers use the EPF8820ATC144-15 to consolidate dozens of 74-series TTL gates, latches, and multiplexers into a single programmable device. With 672 logic elements and 112 I/Os, the FPGA can replace 15-30 standard SSI/MSI packages, reducing PCB real estate and improving reliability. The SRAM-based configuration supports unlimited design iterations during development, and the in-circuit reconfigurability (ICR) feature allows field upgrades via JTAG. The 5 V core and MultiVolt I/O keep the device compatible with legacy 5 V TTL systems. Power estimation for a typical 50%-utilized design is approximately 0.5-1.0 W, easily handled without heatsinking.
おすすめ
Microprocessor Coprocessor Functions
The EPF8820ATC144-15 can offload arithmetic, DMA control, or peripheral management tasks from a host microprocessor. With 672 registers and 8K gates, designers can implement custom instruction decoders, address generators, and timing-critical state machines alongside the CPU. The 112 I/Os provide ample address/data bus connectivity, and the 15 ns speed grade suits most mid-range embedded controllers. According to the FLEX 8000 datasheet, the LAB-based architecture with FastTrack routing delivers predictable timing for synchronous designs. Pair the FPGA with a host CPU and use JTAG for in-system debugging of the coprocessor logic.
おすすめ
High-Speed Industrial Controllers
Industrial control applications such as motor control, PLC scanning, and sensor aggregation benefit from the EPF8820ATC144-15's 112 I/Os and register-rich architecture. The 5 V supply tolerance is well matched to industrial 24 V-derived rails with regulation, and the commercial 0-70 C operating range covers most factory-floor enclosures. With 8K gates, the device can implement PID loops, encoder interfaces, and communication protocol stacks concurrently. The 144-pin TQFP package is robust for vibration-prone industrial environments and is compatible with standard SMT assembly lines.
おすすめ
Legacy System Replacement
When end-of-life notices threaten production of mature 5 V designs, the EPF8820ATC144-15 serves as a form-fit-function alternative to discrete TTL or older PLDs. Because the FLEX 8000 family is mature, the device remains broadly available through authorized distributors and the secondary market, mitigating supply-chain risk. Designers port their schematic-level TTL design into the Altera MAX+PLUS II or Quartus tool flow and validate timing against the -15 grade budget. The same 144-pin TQFP footprint matches many older 144-pin PLCC and PGA FPGA packages, enabling drop-in PCB retrofit without board rework.
おすすめ
DSP Pre/Post-Processing Glue Logic
The FLEX 8000 family datasheet explicitly highlights DSP, wide-data-path manipulation, and data transformation as target applications for the EPF8820ATC144-15. The 672 registers provide ample storage for sample buffering, address generation, and pipeline registers, while the 112 I/Os enable parallel data paths to external DSP chips. The 15 ns speed grade supports sample rates up to approximately 30-40 MHz for moderate-complexity glue logic, suitable for audio processing, video line buffering, and serial protocol framing. Designers pair the FPGA with a dedicated DSP and use the JTAG chain for combined debugging.

設計ノート
The EPF8820ATC144-15 requires a stable 5 V VCCINT and a separate VCCIO rail (3.3 V or 5 V). Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, and add a bulk 10-47 uF tantalum or aluminum polymer capacitor near the device. Estimated: at 50% LE utilization with typical 25 MHz toggle rate, expect 0.5-1.0 W core dissipation - verify with worst-case test vectors because SRAM-based FPGAs draw power proportional to switching activity.
The 144-pin TQFP package has a 0.5 mm pitch and requires precise PCB land pattern per JEDEC MS-026. Use 4-layer board with continuous ground plane under the device for signal integrity and thermal dissipation. Route JTAG signals (TCK, TMS, TDI, TDO) with controlled impedance and keep them short. Configuration signals (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0) should be guarded from noisy nets; route DCLK as a short, clean trace because timing skew corrupts the configuration bitstream.
Do not leave VCCIO floating - tie it to either 3.3 V or 5 V before power-up, or the I/O buffers will be in an undefined state and may source/sink excessive current. The MultiVolt I/O feature is per-bank on larger packages but the EPF8820ATC144-15 typically groups all I/Os into one VCCIO rail, so the entire bank must operate at the same voltage. Also, do not confuse speed grade -15 (15 ns tpd) with -1 (1 ns tpd); same package, very different timing - always re-run static timing analysis when substituting.
For configuration with EPC1/EPC1064 series devices, place the configuration EPROM within 50 mm of the FPGA and route DATA0 directly with no stubs. If using JTAG for in-system programming, daisy-chain the JTAG signals (TCK, TMS, TDI, TDO) across all programmable devices on the board and add a 10 kohm pull-up on TCK, TMS, TDI to VCCIO per IEEE 1149.1 recommendations. The TDO pin does not require a pull-up because it is actively driven.
