Product Summary

The DS1230AB-120 is a 256k Nonvolatile SRAM. It is organized as 32,768 words by 8 bits. Each NV SRAM has a self-contained lithium energy source and control circuitry which constantly monitors VCC for an out-of-tolerance condition. The DS1230AB-120 can be used in place of existing 32k × 8 static RAMs directly conforming to the popular bytewide 28-pin DIP standard. The DIP devices also match the pinout of 28256 EEPROMs, allowing direct substitution while enhancing performance. The DS1230AB-120 in the Low Profile Module package are specifically designed for surface-mount applications. There is no limit on the number of write cycles that can be executed and no additional support circuitry is required for microprocessor interfacing.

Parametrics

DS1230AB-120 absolute maximum ratings: (1)Voltage on Any Pin Relative to Ground: -0.3V to +7.0V; (2)Operating Temperature: 0℃ to 70℃, -40℃ to +85℃ for Ind parts; (3)Storage Temperature: -40℃ to +70℃, -40℃ to +85℃ for Ind parts; (4)Soldering Temperature: 260℃ for 10 seconds.

Features
