EPF8282ATI100-4N Обзор
What is a FLEX 8000 FPGA? The FLEX 8000 (Flexible Logic Element matriX) is a family of SRAM-based programmable logic devices originally introduced by Altera in the mid-1990s. Within the broader hierarchy, FLEX 8000 devices are classified as CPLD/FPGA hybrids (sometimes called "erasable programmable logic devices" or EPLDs) sitting between classic PLDs and modern FPGAs. They provide look-up-table based logic, continuous interconnect, and SRAM configuration memory, differentiating them from non-volatile CPLD families such as MAX 7000.
Key features include 208 logic elements, 282 flip-flops, a maximum of 78 user I/O pins, 5 V tolerant I/O with PCI compatibility, and a continuous, fast-track interconnect fabric. The device supports JTAG boundary-scan testing (IEEE 1149.1), configurable I/O standards, and is available in commercial (0°C to 70°C) or industrial (-40°C to 85°C) temperature grades. The -4N suffix indicates an industrial operating range.
Architecturally, the EPF8282A uses logic array blocks (LABs), each containing 8 LEs and a local interconnect. The FastTrack Interconnect provides row and column channels for signal routing, while embedded logic cells implement combinatorial and registered functions. The chip supports a system clock from a dedicated input or any user I/O.
Typical applications include industrial control glue logic, telecom interface adapters, PCI bus bridges, and legacy system replacements. The FLEX 8000 series is suitable where SRAM-based re-programmability is required but power budget is tight.
When designing with this device, note that the FLEX 8000 family is now NRND/obsolete - Intel recommends migration to the MAX 10 series or Cyclone IV series for new designs. Existing users can verify pinout and timing against the original datasheet and use Altera Quartus II version 13.0 or earlier for legacy support.

Типичное применение
EPF8282ATI100-4N подходит для 6 применениеs: Industrial Control Glue Logic, Telecom Interface Adapters, PCI Bus Bridges and Adapters, Legacy System Replacement and Sustaining, Educational and Development Platforms, Test and Measurement Instrumentation.
Industrial Control Glue Logic
The EPF8282ATI100-4N's industrial operating temperature range (-40°C to +85°C) and 208 logic elements make it suitable for industrial control glue logic applications. The device is used to implement interface bridging, custom state machines, and protocol conversion between PLC subsystems. Its 78 user I/O pins and 5 V I/O tolerance simplify interfacing with legacy industrial sensors, relays, and motor drivers that require 5 V signaling. The 282 flip-flops allow dense registered logic for sequential control, while JTAG boundary-scan supports in-system test on the production line. Estimated: 208 LEs at 5 V typically consume ~150 mA, sufficient for control-panel designs where power budget is not the limiting factor.
Рекомендуется
Telecom Interface Adapters
With 78 user I/O pins and 5 V PCI-compliant signaling, the EPF8282ATI100-4N supports telecom interface adapter designs such as T1/E1 framer interfaces, HDLC controllers, and bus-format converters. The device's SRAM-based programmability enables field upgrades for protocol stack changes without board rework. The FastTrack Interconnect architecture provides predictable timing for synchronous telecom protocols running up to 33 MHz. The 5 V tolerant I/O directly interfaces with legacy telecom backplanes. Engineers designing telecom adapters should note that the FLEX 8000 family has NRND status; production designs should plan migration to Cyclone IV or MAX 10 in subsequent board revisions.
Рекомендуется
PCI Bus Bridges and Adapters
The EPF8282ATI100-4N supports PCI bus bridge implementations through its 5 V PCI-compliant I/O and 78 user I/O pins. The device can implement custom PCI target devices, I/O accelerators, or legacy-PCI-to-ISA bridges. The -4 speed grade (slowest) limits PCI clock to 25 MHz with relaxed timing budgets; for full 33 MHz PCI operation, the -3 or -2 speed grade is recommended. The 208 logic elements are sufficient for typical PCI state machines, FIFOs, and command decoders. SRAM-based configuration allows field firmware updates for bug fixes and protocol extensions. Designers should use Quartus II 13.0 or earlier and follow PCI Local Bus Specification 2.1 compliance guidelines.
Рекомендуется
Legacy System Replacement and Sustaining
For OEM manufacturers with installed bases of legacy equipment, the EPF8282ATI100-4N provides a continuing supply of original-programmable logic for field-replacement boards. Because the device uses SRAM configuration memory, identical bitstreams can be loaded into the EPF8282ATI100-4N or its commercial-temp equivalents (EPF8282ATC100-4N, EPF8282ATC100-4), enabling spare-parts logistics flexibility. Industrial-temperature operation supports outdoor, factory-floor, and transportation applications. Authorized distributors maintain stock for 5-10 year support commitments. Designers should verify PCN/EOLN notices periodically and consider end-of-life planning using the Altera Product Lifecycle data.
Рекомендуется
Educational and Development Platforms
The EPF8282ATI100-4N is widely available on educational FPGA development boards and university course kits due to its low cost, mature Quartus II toolchain support, and forgiving 5 V I/O. Universities and design training programs use this device to teach digital logic design, Verilog/VHDL, and synthesis concepts. The 208 LEs offer enough capacity for student projects such as CPU cores, signal processing pipelines, and custom peripherals. The TQFP-100 package is breadboard-friendly with breakout adapters. While NRND, used and new-old-stock boards remain plentiful on the secondary market at low cost for educational use.
Рекомендуется
Test and Measurement Instrumentation
The EPF8282ATI100-4N's 78 user I/O pins, 5 V I/O tolerance, and JTAG support enable implementation of custom test-pattern generators, protocol analyzers, and instrumentation front-ends. The device's programmable logic fabric allows designers to implement arbitrary waveform sequences, custom trigger logic, and parallel bus monitoring. Industrial temperature range supports use in semi-manufacturing and process-control environments. The -4 speed grade (slowest) is acceptable for instrument-tester communication interfaces but may be limiting for high-speed parallel data acquisition above 25 MHz. Engineers should verify timing margins with the Quartus II timing analyzer tool.

Заметки по проектированию
Estimated: the EPF8282ATI100-4N at 208 LEs with 78 active I/O pins and a 25 MHz clock consumes approximately 150-300 mA at 5 V core supply. Add bulk decoupling capacitors (10 uF tantalum + 0.1 uF ceramic) at each VCCINT pin and one VCCIO pin group. The five VCCINT pins and three VCCIO pins must each be decoupled to reduce ground bounce and switching noise. Power sequencing: 5 V VCCINT and VCCIO can ramp simultaneously; configuration does not begin until VCC reaches stable operating voltage.
The TQFP-100 package has a typical theta_JA of approximately 45 C/W. Estimated: at 1.5 W total dissipation in still air at 25°C ambient, the junction temperature rises about 67°C to roughly 92°C - within industrial limits but approaching the 85°C ceiling in enclosed enclosures. For sealed enclosures or high-altitude deployment, add a heatsink or thermal via array under the package exposed pad. Verify thermal performance in the actual mechanical environment; do not rely on datasheet numbers for sealed designs.
Route configuration clock (DCLK) and configuration data (DATA) traces as short, impedance-controlled nets. Place the configuration EEPROM (such as EPC1064 or EPC1441) within 10 mm of the FLEX 8000 device on a dedicated SPI-like bus. Decoupling capacitors must be placed within 3 mm of each power pin. Use a 4-layer PCB with dedicated ground and power planes for the FLEX 8000 device area; signal layers should be routed directly over ground plane to control impedance and reduce EMI on the high-speed JTAG clock.
Do not confuse the FLEX 8000 (SRAM-based, EPF8282A) with the MAX 7000 (EEPROM-based, EPM7xxx). They have different package pinouts and configuration schemes. Verify the configuration mode (MSEL0, MSEL1) matches the configuration memory device used. For JTAG programming, ensure TRST is properly handled or tied per datasheet. When migrating from -4 to -3 speed grade, update the Quartus II fitter constraints for the new timing model; existing bitstreams are not compatible across speed grades.
