EP1K100QC208-2NGZ Ringkasan

The Intel / Altera EP1K100QC208-2NGZ is a member of the legacy ACEX-1K family of Field Programmable Gate Arrays (FPGAs), delivering 100,000 typical gates and 4,992 logic elements in a 208-pin Plastic Quad Flat Pack (208-BFQFP / 208-PQFP) surface-mount package. The device integrates 624 Logic Array Blocks (LABs) / Configurable Logic Blocks (CLBs), 49,152 bits of embedded SRAM, 147 user I/O pins, and operates from a 2.375V to 2.625V core supply with a commercial 0°C to 70°C temperature grade.

What is an FPGA? A Field Programmable Gate Array is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs/LABs) connected by a programmable interconnect matrix. Unlike an ASIC (Application-Specific Integrated Circuit), an FPGA can be reconfigured in the field after manufacturing, making it ideal for prototyping, low-volume production, glue logic, and applications where design changes are expected. Within the FPGA taxonomy, the EP1K100 sits at the lower-density end: CPLD -> low-density FPGA -> ACEX-1K -> high-density FPGA -> SoC FPGA.

Key specifications include a 2.5V core supply with 5V-tolerant I/O, in-system programmability via the Altera ByteBlaster or BitBlaster configuration interface, and JTAG boundary-scan support. The 'QC208' package code denotes the 208-pin Plastic QFP, the '-2' speed grade indicates the medium-speed tier, and the 'NGZ' suffix indicates the lead-free, RoHS-compliant commercial processing variant.

The EP1K100QC208-2NGZ uses a SRAM-based Look-Up Table (LUT) architecture with four-input LUTs per logic element, and a hierarchical interconnect structure with FastTrack routing. The embedded array blocks (EABs) provide dedicated dual-port RAM resources that are widely used for FIFO buffers and small register files. Configuration data is loaded from an external serial or parallel PROM at power-up, since the SRAM cells are volatile.

Typical applications include digital signal processing front-ends, industrial control glue logic, telecommunications line-card interfaces, PCI bridge controllers, and legacy embedded systems where the ACEX-1K has been a long-standing design-in. The 147 user I/Os are sufficient to drive multiple 16/32-bit buses and external memory interfaces in cost-sensitive designs.

When designing with this device, ensure that configuration memory (typically an EPC2 or EPC16) is included in the BOM, since the EP1K100 has no on-chip non-volatile configuration storage. Decoupling must follow the ACEX-1K Hardware Reference Manual guidelines: 0.1µF + 10µF near each VCCINT pin group. Note that ACEX-1K is now in legacy/discontinued status, so designers should evaluate Cyclone or Cyclone II for new designs.
