EPF8282ATI100-4N 概覽

The Intel / Altera EPF8282ATI100-4N is a member of the FLEX 8000 family of CMOS SRAM-based programmable logic devices, delivering 208 logic elements (LEs) and 282 flip-flops in a 100-pin TQFP (S-PQFP-G100) industrial-temperature package. The device features a 5 V core supply, in-system programmability via an EPROM/EEPROM controller, and is built on a 0.42 µm CMOS process with four-sided I/O flexibility. This part corresponds to the -4 speed grade, the slowest of the FLEX 8000 family grades, traded off for the lowest unit cost.

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.

EPF8282ATI100-4N 適用於 6 應用s: 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.

🌐

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.

🖥️

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.

Both share the same 100-pin TQFP package, 208 logic elements, 282 flip-flops, and -4 speed grade. They are functionally and pin-compatible; the only differing parameter is the operating temperature range. Choose the 'I' (industrial) variant for harsh-environment applications.

What is the difference between EPF8282ATI100-4N and EPF8282ATI100-3N?

Both devices share the same 100-pin TQFP package, 208 logic elements, and industrial temperature range. The difference is the speed grade: -4 is the slowest grade, while -3 is faster. The -3N achieves shorter propagation delays and is suitable for higher-performance designs. Both are pin-to-pin compatible, allowing the -3N to be used as a drop-in upgrade for the -4N where timing margins are tight.

What is a drop-in replacement for EPF8282ATI100-4N?

Direct drop-in replacements (same 100-pin TQFP footprint, pin-to-pin compatible) include the EPF8282ATC100-4N (commercial temperature), EPF8282ATC100-4 (commercial, -4 grade), EPF8282ATC100-3 (commercial, faster speed grade), EPF8282ATC100-2W (commercial, -2 grade with W suffix), and EPF8282ATC100-2 (commercial, fastest -2 grade). All five alternatives share the same TQFP-100 package and are interchangeable if temperature grade differences are acceptable.

Which software is used to program the EPF8282ATI100-4N?

The EPF8282ATI100-4N is programmed using Altera Quartus II version 13.0 or earlier, as newer Quartus releases do not support legacy FLEX 8000 devices. Quartus II Web Edition (free) supports the EPF8282A device family. For design capture, designers can use schematic entry, AHDL, or VHDL/Verilog HDL. JTAG programming is performed via the Altera ByteBlasterMV or USB-Blaster download cable using the FLEX 8000 device programming files.

How many user I/O pins does EPF8282ATI100-4N have?

The EPF8282ATI100-4N provides 78 user I/O pins out of 100 total package pins, according to the FLEX 8000 datasheet. The remaining 22 pins are dedicated to power (VCC), ground (GND), JTAG (TCK, TMS, TDI, TDO), configuration control (nCONFIG, nSTATUS, CONF_DONE), and special-function pins (DEV_CLRn, DEV_OE, MSELn). All 78 I/O pins support 5 V PCI-compliant signaling.

What are the key specifications of EPF8282ATI100-4N that engineers should know?

The EPF8282ATI100-4N key specifications are: 208 logic elements, 282 flip-flops, 78 user I/O pins, 5 V core supply, industrial temperature range (-40°C to +85°C), -4 speed grade, JTAG boundary scan, and SRAM-based configuration. The device is built on 0.42 µm CMOS and housed in a 100-pin TQFP package. These specs make it suitable for legacy industrial control and telecom interface designs where reprogrammability is required.

Is EPF8282ATI100-4N RoHS compliant?

Yes, the EPF8282ATI100-4N is RoHS compliant per the manufacturer datasheet and product page. The device is also lead-free, with MSL Level 3 (168 hours) moisture sensitivity classification. The package is a 100-pin TQFP (S-PQFP-G100) with matte-tin lead-free plating. For automotive applications requiring AEC-Q100 qualification, the FLEX 8000 family is not qualified - choose a different part for automotive use.

Can MAX 10 replace EPF8282ATI100-4N in legacy designs?

No, the MAX 10 series is NOT a drop-in replacement for the EPF8282ATI100-4N. MAX 10 is a non-volatile (flash-based) CPLD/FPGA hybrid in TQFP-100 and BGA packages, but with different pinout, different I/O voltage standards, and different configuration architecture. Migration from FLEX 8000 to MAX 10 requires PCB redesign and software migration to Quartus Prime. For true drop-in replacement, use another FLEX 8282 family device in the same TQFP-100 package.

Where can I download the EPF8282ATI100-4N datasheet PDF?

The EPF8282ATI100-4N datasheet is available as a PDF from Intel's Altera website at https://www.altera.com/literature/ds/dsf8000.pdf, which covers the entire FLEX 8000 family datasheet. The document contains device pinouts, electrical characteristics, AC timing specifications, and configuration guidelines. Distributors such as DigiKey, Mouser, and FPGAkey also provide datasheet PDFs on their product detail pages.

What is the pinout of EPF8282ATI100-4N in TQFP-100 package?

The EPF8282ATI100-4N uses a 100-pin TQFP (S-PQFP-G100) package with 78 user I/O pins, 8 GND pins, 4 VCC pins, 4 JTAG pins (TCK/TMS/TDI/TDO), 4 configuration control pins (nCONFIG/nSTATUS/CONF_DONE/MSELn), and 2 special-function pins (DEV_CLRn/DEV_OE). Pin 1 is at the top-left corner of the package with the standard TQFP pin numbering (counter-clockwise). Refer to the FLEX 8000 datasheet pinout table for the exact pin assignments.

What is the lead time for EPF8282ATI100-4N?

Lead time for the EPF8282ATI100-4N varies by distributor. As of 2026-09-12, authorized distributors such as Win Source, Jotrin, and MFMIC list the part in stock with immediate availability for small quantities. For large quantities (1000+ units), lead time is typically 4-8 weeks due to NRND/limited production status. Buyers should confirm lead time directly with the distributor at the time of order, as Intel/Altera does not guarantee long-term supply for FLEX 8000 devices.

選型指南

Choose the EPF8282ATI100-4N when your design needs a low-cost, industrial-temperature ( -40C to +85C) FLEX 8000 series FPGA with 208 logic elements in a surface-mount TQFP-100 package and your timing budget fits the -4 speed grade (slowest). For commercial-temperature designs (0C to +70C), use the pin-compatible EPF8282ATC100-4N for the same functionality at typically lower cost. For higher-performance designs needing faster timing closure, choose the EPF8282ATI100-3N (industrial, -3 speed grade) - it shares the same TQFP-100 footprint. For new designs, however, Intel recommends migrating to MAX 10 or Cyclone IV as the FLEX 8000 family is NRND. Reserve the EPF8282ATI100-4N for legacy spare-parts, educational, and existing-production applications only.

設計說明

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.
