PUMA68SV16000X-020 Datasheet, PDF (1/12 Pages) MOSAIC – 512 K x 32 Static RAM

PUMA 68SV16000X - 020/025
Issue 5.2 April 2001
Description
The PUMA68 range of devices provide a high
density surface mount industry standard memory
solution which may accommodate various memory
technologies including SRAM, EEPROM and
Flash. The devices are designed to offer a defined
upgrade path and may be user configured as 8, 16
or 32 bits wide.
The PUMA68SV16000X is a 512Kx32 SRAM mod-
ule housed in a 68 Jleaded package which complies
with the JEDEC 68 PLCC standard. Access times of
20 or 25ns are available. The 3.3V low voltage
device is available to commercial and industrial
temperature grade.
64Kx32, 128Kx32 and 256Kx32 SRAM PUMA68
devices are available in the same footprint. The
upgrade part (1Mx32 SRAM) is planned.
