ispMACH4256V-TN144 CPLD
The board features the ispMACH 4256V CPLD which is ideal for low-power, high-volume portable applications. The
on-board ispMACH 4256V is the highest capacity device of the family with 256 macrocells (equivalent to about 450
FPGA LUTs). The 144-pin TQFP package provides 96 user I/Os and 4 dedicated inputs in a 20 mm x 20 mm pack-
age. The ispMACH 4256V consumes standby current as low as 15 µA. A complete description of this device can be
found in DS1020,
