Speed, I/O, and supply rails for board-level fit
The EPM570M100C5N: Propagation delay tpd1(max) is 5.4 ns, which sets the combinatorial path limit — for a 50 MHz bus the 20 ns period leaves 14.6 ns of timing margin after the CPLD delay, enough for most address-decoding and state-machine logic without pipeline registers. Operating temperature range is 0°C to 85°C (TJ) — commercial grade, suited for indoor equipment, telecom racks, and industrial control cabinets where ambient stays below 70°C.
Package and board integration for the 100-TFBGA
The 100-ball TFBGA (6x6 mm, 0.65 mm pitch) requires a 4-layer PCB for fan-out — the inner balls route through microvias to inner layers, while the outer two rows break out on the top layer. A 0.30 mm via pad and 0.15 mm drill keep the escape routing feasible. The device is in-system programmable via the JTAG interface — no socket or pre-programming needed; the design can be updated on the assembled board through the 4-pin header. Supplied in tray format — the 100-TFBGA trays are JEDEC-standard, compatible with pick-and-place feeders without tooling change.
Sourcing posture for the active MAX II line
The MAX II family has been a long-running production line, and the 100-TFBGA package is a standard offering that is unlikely to see a short-notice discontinuation.
