EPF8282AVTC100-3 Ringkasan

The Altera EPF8282AVTC100-3 is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs), offering 78 user I/O pins, 208 logic elements, 2.5K equivalent gates, and a -3 speed grade in a 100-pin TQFP (14x14 mm) package. It operates from a single 4.75V to 5.25V supply and is fabricated on a 0.42 µm CMOS process delivering typical toggle rates up to 125 MHz.

An FPGA is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be re-programmed to implement arbitrary digital logic. FPGAs sit between discrete logic ICs and ASICs in the design hierarchy, offering higher integration than glue logic, faster time-to-market than masked ASICs, and lower per-unit cost than full-custom designs. The FLEX 8000 family specifically targets high-density register-rich designs with predictable timing and in-system reconfigurability.

Key features include in-circuit reconfigurability via Altera EPC1, EPC1064, EPC1213, and EPC1441 configuration devices, four dedicated input pins, JTAG boundary-scan support, and tri-state output buffers with programmable slew rate. The -3 speed grade specifies a 6 ns typical propagation delay through logic elements, making the device suitable for moderate-speed control, glue-logic, and bus-interface applications. The 100-pin TQFP package supports standard surface-mount assembly flows and provides a robust industrial footprint.

The architecture combines fine-grained Look-Up Tables (LUTs) with FastTrack interconnect for deterministic routing delays. Each Logic Element (LE) contains a 4-input LUT, a programmable register, and dedicated carry and cascade chains for arithmetic and wide-function operations. The 208-cell logic capacity yields approximately 2,500 usable gates, positioning the EPF8282 between small CPLDs and larger FPGAs and giving designers headroom to consolidate multiple discrete logic devices into a single programmable part.

Typical applications include industrial control logic, glue-logic consolidation, bus-interface bridges (PCI, ISA, VME), DSP co-processing front-ends, and legacy system upgrades where pin-compatible replacement of discrete 74LS/74F logic is needed. The SRAM-based configuration means the design must be loaded at every power-up, typically from a serial configuration PROM.

When designing with this part, allow at least 50 ms of configuration time at power-on before the device becomes active, ensure the 5V supply stays within 4.75V-5.25V under transients, and provide 0.1 µF decoupling capacitors adjacent to every VCC pin. JTAG pins (TCK, TMS, TDI, TDO, TRST) should be pulled or terminated per the IEEE 1149.1 standard for reliable boundary-scan operation.
