EP1K100QI208-3 Ringkasan

The Altera EP1K100QI208-3 is a member of the FLEX 10K / ACEX 1K family of CMOS Field Programmable Gate Arrays, delivering approximately 100,000 gates organized as 4,992 logic cells across 624 Configurable Logic Blocks (CLBs). Housed in a 208-pin Power Quad Flat Pack (PQFP / QFP, gull-wing) package, the device provides 147 general-purpose user I/O pins plus 6 dedicated inputs, targeting high-performance logic, glue-logic, and DSP datapath applications. It is built on a 2.5 V nominal core supply (max 2.625 V) and operates over the industrial temperature range of -40 °C to +85 °C.

A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines an array of configurable logic blocks, programmable interconnect, and I/O cells on a single CMOS die. The ACEX 1K family sits in the hierarchy: programmable logic device -> CPLD/FPGA -> SRAM-based FPGA -> ACEX 1K, representing one of the early low-cost, high-volume SRAM-lookup-table FPGA families from Altera (later acquired by Intel). Each logic element uses a 4-input LUT plus a register, and the embedded array blocks (EABs) can be configured as RAM, ROM, or multiplier primitives, allowing designers to mix datapath and control logic without external memory.

Key features include 4,992 logic cells / 624 CLBs, ~100 K system gates, 147 user I/Os, an embedded array block memory architecture, JTAG-based IEEE 1149.1 boundary-scan support, and an SRAM-based configuration cell that loads from a serial or parallel EPROM. The "-3" speed grade corresponds to the fastest commercial timing bin offered for this device family, enabling higher fMAX on internal logic and shorter pin-to-pin tPD delays than the slower -1 or -2 grades. The PQFP-208 package has a thermal resistance suitable for forced-air or large-copper PCB designs commonly used in telecom and industrial control chassis.

Typical applications include telecommunications line-card glue logic, industrial motor-control state machines, ASIC prototyping, DSP pre/post-processing pipelines, and legacy PCI/ISA bus-interface bridges where the 5 V-tolerant I/O and rich register fabric are advantageous. Designers often pair the EP1K100QI208-3 with an EPC2 configuration device to store the bitstream.

When designing with this part, ensure the JTAG chain is correctly ordered with any downstream devices, since multi-device scan chains are a common source of configuration failures. Verify the configuration mode (AS, PS, or JTAG) matches the EPC2 / EPC4 selected, and never apply VCC before the configuration device is stable.
