STMicroelectronics M48Z35
The M48Z35/Y ZEROPOWER® RAM is a 32 K x 8, non-volatile static RAM that integrates powerfail deselect circuitry and battery control logic on a single die. The monolithic chip is available in two special packages to provide a highly integrated battery-backed memory solution. The M48Z35/Y is a non-volatile pin and function equivalent to any JEDEC standard 32 K x 8 SRAM.| Part No. | M48Z35 |

FEATURES
● Integrated, ultra low power SRAM, power-fail control circuit, and battery● READ cycle time equals WRITE cycle time
● Automatic power-fail chip deselect and WRITE protection
● WRITE protect voltages: (VPFD = power-fail deselect voltage)
● M48Z35: VCC = 4.75 to 5.5 V; 4.5 V ≤ VPFD ≤ 4.75 V
● M48Z35Y: 4.5 to 5.5 V; 4.2 V ≤ VPFD ≤ 4.5 V
● Self-contained battery in the CAPHAT™ DIP package
● Packaging includes a 28-lead SOIC and SNAPHAT® top (to be ordered separately)
● Pin and function compatible with JEDEC standard 32 K x 8 SRAMs
● SOIC package provides direct connection for a SNAPHAT® top which contains the battery
● RoHS compliant
● Lead-free second level interconnect
DESCRIPTION
It also easily fits into many ROM, EPROM, and EEPROM sockets, providing the non-volatility of PROMs without any requirement for special WRITE timing or limitations on the number of WRITEs that can be performed. The 28-pin 600 mil DIP CAPHAT™ houses the M48Z35/Y silicon with a long life lithium button cell in a single package.
