 Product Description for Better Enquiries

 

This chip is a Ferroelectric RAM (F-RAM), offering the best features of both RAM and ROM in one package. 
It delivers instantaneous, high-speed data saving similar to RAM, but holds all data forever without power, like flash memory. 
Crucially, it provides an unrivaled 10 Trillion write cycles, meaning you can log data continuously for decades without wear-out issues seen in traditional flash memory.
Operating on a simple I2C bus and a wide voltage range 2.7V TO 5.5V , this chip is perfect for applications requiring high reliability, frequent data logging, and low power consumption in industrial and utility metering devices.

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

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. 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.
