Typical Applications
EPF8282AVTC100-4 is suitable for 6 applications: 32-Bit Bus Interface Bridge, Legacy Industrial Glue Logic, Telecom Datacom Backplane Interface, DSP Pre-Processing Front-End, Peripheral Controller and Custom State Machine, Prototyping Platform for Modern FPGA Migration.
32-Bit Bus Interface Bridge
The EPF8282AVTC100-4 fits 32-bit bus bridging applications because the 100-TQFP package provides 78 user I/O - enough to multiplex two 32-bit buses with control signals plus chip selects and interrupts. The 2,500 usable gates and 208 logic cells are sufficient to implement address decoding, wait-state insertion, and byte-enable logic for legacy PCI-to-ISA or VME-to-local-bus bridges running at 33 MHz. The 5 V tolerant I/O is critical when bridging between 3.3 V core logic and 5 V peripheral buses common in industrial control systems. Unlike a CPLD, the SRAM-based configuration allows in-system reconfiguration for field firmware updates, useful for deployed bridge cards that must support evolving bus standards.
Recommended
Legacy Industrial Glue Logic
For replacing 5 to 15 discrete 74-series TTL/CMOS glue-logic ICs on a board, the EPF8282AVTC100-4 offers 208 logic elements and 282 flip-flops in a single 100-TQFP footprint, simplifying BOM and improving reliability. The 5 V core supply matches the legacy TTL rails still common in factory automation, motor drives, and PLC I/O modules. Designers can consolidate address decoding, interrupt prioritization, and watchdog timer logic into one programmable device, reducing PCB area by 60-70% compared to discrete implementations. The 125 MHz internal frequency is more than adequate for sub-microsecond control loops typical in PLC scan engines.
Recommended
Telecom Datacom Backplane Interface
The EPF8282AVTC100-4 is well-suited to telecom backplane applications including T1/E1 framers, HDLC controllers, and low-speed SONET/SDH tributary mapping where 2,500 gates of logic and 78 I/O are sufficient. The -4 speed grade's 125 MHz toggle rate supports STS-1 (51.84 MHz) and STM-1 processing with comfortable timing margin. Multi-volt I/O (3.3 V and 5 V) allows direct interfacing to legacy bus-switch ASICs without level translators. Configuration via EPC1/EPC1064/EPC1213 serial PROMs keeps board area minimal for compact line-card designs.
Recommended
DSP Pre-Processing Front-End
For DSP pre-processing tasks such as FIR filter coefficient loading, data path multiplexing, and FFT bit-reversal addressing, the EPF8282AVTC100-4's 282 flip-flops and fast carry chains handle 16-bit datapath glue at audio sample rates up to 192 kHz. The 100-TQFP package is hand-solderable, simplifying prototype builds. Designers pair this FPGA with a fixed-point DSP (e.g., TMS320C50) to offload address generation and I/O formatting, freeing DSP MIPS for the core algorithm. The 5 V supply and 0.42 Β΅m process provide high noise immunity critical in mixed-signal audio boards.
Recommended
Peripheral Controller and Custom State Machine
The EPF8282AVTC100-4 is ideal for implementing custom peripheral controllers - IDE/ATA bus controllers, SCSI protocol engines, or proprietary sensor interfaces - that need deterministic timing and parallel execution impossible in microcontrollers. With 208 logic elements and 125 MHz internal frequency, the device can handle multi-state protocols requiring simultaneous monitoring of 10+ control lines. The SRAM-based configuration allows firmware upgrades in the field for evolving protocol standards. Low-volume industrial OEMs benefit from the FLEX 8000's mature Altera Quartus toolchain, which still supports legacy design files.
Recommended
Prototyping Platform for Modern FPGA Migration
Engineers use the EPF8282AVTC100-4 in legacy prototype boards as a known-good logic substitute while they migrate designs to modern Cyclone IV or Cyclone 10 LP devices. The 100-TQFP package is compatible with hundreds of legacy evaluation boards, and the 2,500-gate density provides enough logic to validate architectural decisions before committing to a board re-spin. Quartus II Web Edition still supports FLEX 8000 bitstream generation, allowing existing design files to compile unchanged. Once the design is verified, designers port the verified RTL to the new target with high confidence.

Key Differentiators
- Highest speed grade in the FLEX 8000 100-TQFP family (vs EPF8282AVTC100-3)
- Commercial temperature range at the same package/density (vs EPF8282ATC100-4N)
- Largest I/O count in the 100-TQFP FLEX 8000 lineup (vs EPF8282ATC100-2)
Design Notes
The EPF8282AVTC100-4 requires a stable 5 V +/- 5% supply on all VCCINT pins and a separate 3.3 V or 5 V rail on VCCIO pins. Place 0.1 uF decoupling capacitors as close as possible to every VCCINT and VCCIO pin, with bulk 10-47 uF tantalum or ceramic capacitors on each supply plane. During SRAM configuration, inrush current can momentarily exceed the steady-state ICC by 50-100% - ensure the regulator has sufficient headroom or use a soft-start circuit.
The 100-TQFP package uses 0.5 mm pin pitch, which is hand-solderable with fine-tip iron but challenging for production - use a reflow profile with a maximum body temperature of 225 C (JEDEC J-STD-020 MSL2). Reserve a 14 x 14 mm land pattern with 0.3 mm wide traces to each I/O pad, and route all configuration pins (DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE) away from high-speed switching signals to avoid configuration glitches during power-up.
Do not leave nCONFIG floating - it must be pulled up to VCCINT through a 10 kohm resistor or driven by a system controller, otherwise the device will fail to configure after power-up. CONF_DONE is open-drain and requires an external pull-up to VCCINT. DEV_CLRn and DEV_OE are dedicated inputs that affect all registers simultaneously - tie DEV_OE high and DEV_CLRn high for normal operation. Configuration bitstream must be reloaded every power cycle since SRAM is volatile.
Compliance Information
RoHS, REACH, lead-free, halogen-free status not explicitly confirmed in the verified web data; use [DATA_NEEDED] for missing compliance fields. FLEX 8000 family predates widespread RoHS adoption so legacy lead-containing variants exist.
