2M x 8 SRAM MODULE
SYS82000RKXD - 85/10/12
Issue 1.4 : April 2001
Description
The SYS82000RKXD is a plastic 16Mbit Static
RAM Module housed in a standard 36 pin Single-In-
Line package organised as 2M x 8. This offers an
extremely high PCB packing density.
The module is constructed using four 512Kx8
SRAMs in TSOPII packages mounted on a FR4
epoxy substrate. Access times are 85, 100 and
120ns.
The SYS82000RKXD is offered in standard and low
power versions, with the -L module having a low
voltage data retention mode for battery backed
applications.
