GR12883 Overview
The GR12883 is a 131072 word by 8 bits (128K x 8) non-volatile CMOS Static Ram, fabricated from advanced silicon gate CMOS technology and a high reliability lithium power cell. The power down circuit is fully automatic and is referenced at 4.5 volts. At this point the GR12883 is write protected by an internal inhibit function for Data Protection and the memory contents are retained by the lithium power source.
