ST M48Z512A M48Z512AY M48Z512AV 4 Mbit (512 Kbit x 8) ZEROPOWER SRAM handbook
The M48Z512A, M48Z512AY, and M48Z512AV are non-volatile, 4 Mbit static RAM devices organized as 524,288 words by 8 bits. These devices combine an internal lithium battery, a CMOS SRAM, and a control circuit in a 32-pin plastic DIP module. They provide conventional SRAM operation with unlimited write cycles and 10 years of data retention in the absence of power.
