P10C68/P11C68

PRELIMINARY INFORMATION

DS3600-1.2 September 1992

P10C68/P11C68

(Previously PNC10C68 and PNC11C68

)

CMOS/SNOS NVSRAM

HIGH PERFORMANCE 8 K x 8 NON-VOLATILE STATIC RAM

(Supersedes DS3159-1.3, DS3160-1.3, DS3234-1.1, DS3235-1.1)

The P10C68 and P11C68 are fast static RAMs (35 and 45

ns) with a non-volatile electically-erasable PROM (EEPROM)

cell incorporating in each static memory cell. The SRAM can

be read and written an unlimited number of times while

independent non-volatile data resides in PROM.

On the P10C68 data may easily be transferred from the

SRAM to the EEPROM (STORE) and from the EEPROM back

to the SRAM ( RECALL) using the NE (bar) pin. The Store and

Recall cycles are initiated through software sequences on the

P11C68. These devices combine the high performance and

ease of use of a fast SRAM with the data integrity of non-

volatility.

The P10C68 and P11C68 feature the industry standard

pinout for non-volatile RAMs in a 28-pin 0.3-inch plastic and

ceramic dual-in-line packages.
