MAX II CPLD — 570 LE, 5.4 ns, industrial temp
The Intel EPM570M100I5N is a MAX® II family CPLD with 570 logic elements and 440 macrocells in a 100-ball TFBGA (6x6 mm) package. It delivers a 5.4 ns pin-to-pin propagation delay.
76 I/O in a 6x6 mm BGA — board-fit constraints
The 100-TFBGA (MBGA) footprint measures 6x6 mm. That 76 user I/O count in a compact array means the board layout needs fine-trace escape routing.
The 5.4 ns propagation delay (tpd1) is the combinatorial path from any pin through the logic array to any output. For address decoding, chip-select generation, or state-machine glue logic, that timing keeps the critical path under one clock cycle at 100+ MHz system clocks. The MAX II architecture uses a look-up-table (LUT) based core rather than the sum-of-products fabric of the older MAX 7000 series — so the 5.4 ns is a LUT delay, not a PAL-type AND-OR delay. If you are replacing a MAX 7000 part (e.g., EPM7128 with 7.5 ns tpd), this part is faster and denser, but the logic mapping tool (Quartus II) handles the translation.
