M48Z129V-85PM1

The M48Z129V-85PM1 is a 1,048,576 bit non-volatile static RAM organized as 131,072 words by 8 bits. The device combines an internal lithium battery, a CMOS SRAM and a control circuit in a plastic 32 pin DIP Module. The M48Z129V-85PM1 directly replaces industry standard 128K x 8 SRAM. It also provides the non-volatility of FLASH without any requirement for special write timing or limitations on the number of writes that can be performed.

The features of the M48Z129V-85PM1 are: (1)integrated ultra low power sram, power-fail control circuit, and battery; (2)automatic power-fail chip deselect and write protection; (3)microprocessor power-on reset (reset valid even during battery back-up mode); (4)battery low pin - provides warning of battery end-of-life; (5)write protect voltages (vpfd = power-fail deselect voltage): 2.7v vpfd 3.0v; (6)conventional sram operation; unlimited write cycles; (7)10 years of data retention in the absence of power; (8)pin and function compatible with jedec standard 128kb x 8 srams; (9)self contained battery in dip package.

The absolute maximum ratings of the M48Z129V-85PM1 are: (1)Operating Temperature: 0 to 70 °C; (2)Storage Temperature (VCC, Oscillator Off): 40 to 70 °C; (3)Lead Solder Temperature for 10 seconds: 260 °C; (4)Supply Voltage (on any pin relative to Ground): 0.3 to +4.6 V; (5)Input or Output Voltages: 0.3 to VCC + 0.3 V; (6)Supply Voltage: 0.3 to 7.0V.
