The PUMA68S4000/A is a 4Mbit CMOS High
Speed Static RAM organised as 128K x 32 in a
JEDEC 68 pin surface mount PLCC, available with
access times of 20, 25, 35, and 45ns. The output
width is user configurable as 8 , 16 or 32 bits using
four Chip Selects (CS1~4).
The device features multiple ground pins for
maximum noise immunity and TTL compatible
inputs and outputs. The PUMA 68S4000/A offers a
dramatic space saving advantage over four
standard 128Kx8 devices.
