Product Summary

The DS1230 256k Nonvolatile SRAMs are 262,144-bit, fully static, nonvolatile SRAMs organized as 32,768 words by 8 bits. Each NV SRAM has a self-contained lithium energy source and control circuitrywhich constantly monitors VCC for an out-of-tolerance condition. When such a situation occurs, the lithium energy source is automatically switched on and write protection is unconditionally enabled toprevent data corruption. DIP-package DS1230 devices can be used in place of existing 32k x 8 staticRAMs 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.

Parametrics

The absolute maximum ratings of DS1230Y-100 are
(1)Voltage on Any Pin Relative to Ground: -0.3V to +7.0V;
(2)Operating Temperature: 0°C to 70°C, -40°C to +85°C for IND parts;
(3)Storage Temperature: -40°C to +70°C, -40°C to +85°C for IND parts;
(4)Soldering Temperature: 260°C for 10 seconds

Features

The features of DS1230Y-100 can be summarized as (1)10 years minimum data retention in theabsence of external power; (2)Data is automatically protected during powerloss; (3)Replaces 32k x 8 volatile static RAM,EEPROM or Flash memory; (4)Unlimited write cycles; (5)Low-power CMOS; (6)Read and write access times as fast as 70 ns; (7)Lithium energy source is electrically disconnected to retain freshness until power isapplied for the first time; (8)Full±10% VCC operating range (DS1230Y); (9)Optional±5% VCC operating range(DS1230AB); (10)Optional industrial temperature range of-40°C to +85°C, designated IND; (11)JEDEC standard 28-pin DIP package; (12)New PowerCap Module (PCM) package
