MAX II CPLD — 570 logic elements in a 256-ball BGA
The Altera EPM570ZM256I8N is a MAX II family CPLD packing 570 logic elements and 440 macrocells in a 256-ball MBGA (11x11 mm) footprint. It delivers 160 user I/O with a 9 ns pin-to-pin propagation delay, running on a 1.71 V to 1.89 V core supply. In-system programmability via JTAG means you can update the glue logic without pulling the board — useful for field revisions or multi-configuration boot sequences.
9 ns tpd — what it buys on the bus
The 9 ns propagation delay is the combinatorial path from any input to any output through one macrocell.
