DS1220AB-100IND - 16k Nonvolatile SRAM

FEATURES 

? 10 years minimum data retention in the 

absence of external power 

? Data is automatically protected during power 

loss 

? Directly replaces 2k x 8 volatile static RAM 

or EEPROM 

? Unlimited write cycles 

? Low-power CMOS 

? JEDEC standard 24-pin DIP package 

? Read and write access times of 100 ns 

? Lithium energy source is electrically 

disconnected to retain freshness until power 

is applied for the first time 

? Full ±10% VCC operating range (DS1220AD) 

? Optional ±5% VCC operating range 

(DS1220AB) 

? Optional industrial temperature ra 

DESCRIPTION 

The DS1220AB and DS1220AD 16k Nonvolatile SRAMs are 16,384-bit, fully static, nonvolatile SRAMs 

organized as 2048 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. When such a condition 

occurs, the lithium energy source is automatically switched on and write protection is unconditionally 

enabled to prevent data corruption. The NV SRAMs can be used in place of existing 2k x 8 SRAMs 

directly conforming to the popular bytewide 24-pin DIP standard. The devices also match the pinout of 

the 2716 EPROM and the 2816 EEPROM, allowing direct substitution while enhancing performance. 

There is no limit on the number of write cycles that can be executed and no additional support circuitry is 

required for microprocessor interfacing.
