440 macrocells, 5.4 ns pin-to-pin — the MAX II sweet spot
The Intel EPM570GF100I5N is a MAX® II family CPLD packing 440 macrocells and 570 logic elements in a 100-ball FBGA (11x11 mm). The 5.4 ns propagation delay (tpd1 max) means glue logic, address decoding, or state-machine control fits within a single clock cycle at common bus speeds — no pipeline stages needed for 100 MHz+ interfaces. 76 user I/O in the 100-LBGA package gives enough headroom for a 16-bit data bus plus control signals, with spare pins for board-level test access or a JTAG chain. The 1.71 V to 1.89 V core supply keeps dynamic power low — a consideration when the CPLD sits on a 1.8 V rail shared with an FPGA or processor.
In-system programmable — no socket, no UV eraser
In-system programmability (ISP) via JTAG means the EPM570GF100I5N can be populated, reflowed, and programmed on the board — no separate programming socket or UV eraser needed. This simplifies prototype spins and field updates: the same BOM position accepts multiple logic revisions without a hardware change.
