描述 Description

The AT59C11/22/13 provides 1024/2048/4096 bits of serial EEPROM (Electrically Erasable Programmable Read Only Memory) organized as 64/128/256 words of 16 bits each, when the ORG Pin is connected to VCC and 128/256/512 words of 8 bits each when it is tied to ground. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The AT59C11/22/13 is available in space saving 8-pin PDIP and 8-pin EIAJ SOIC packages.
