GR3281 - NON-VOLATILE RAM

Datasheet Summary

Description

The GR3281 is a 32768 word by 8 bits (32K x 8) non-volatile CMOS Static Ram, fabricated from advanced silicon gate CMOS technology and a high reliability lithium power cell.

The pin-out of the GR3281 conforms to the JEDEC standards and is fully compatible with normal static RAM.

GR3281 (32K x 8) NON-VOLATILE RAM ABSOLUTE MAXIMUM RATINGS Symbol Vdd Vi/o Temp Min – 0.3 – 0.3 – 20 Max 7.0 Vdd +0.3 +70 Units Volts Volts deg. C DESCRIPTION The GR3281 is a 32768 word by 8 bits (32K x 8) non-volatile CMOS Static Ram, fabricated from advanced silicon gate CMOS technology and a high reliability lithium power cell. The pin-out of the GR3281 conforms to the JEDEC standards and is fully compatible with normal static RAM. The power down circuit is fully automatic and is referenced at 4.5 volts. At this point the GR3281 is write protected by an internal inhibit function for Data Protection and the memory contents are retained by OPERATING CONDITIONS Symbol Min Vdd 4.75 Vin (1) 2.2 Vin (0) Iin (any other pin) – 1.0 Vout (1)(Iout = –1mA) 2.
