2M x 8 SRAM MODULE
SYS82000RKXC - 70/85/10/12
Issue 1.3 : April 2001
Description
The SYS82000RKXC is a plastic 16Mbit Static
RAM Module housed in a standard 38 pin Single In-
Line package organised as 2M x 8 with access
times of 85,100, or 120 ns.
The module is constructed using four 512Kx8
SRAMs in TSOPII packages mounted onto an FR4
epoxy substrate. This offers an extremely high
PCB packing density.
The device is offered in standard and low power
versions, with the -L module having a low voltage
data retention mode for battery backed applications.
