IN93AA56N, IN93AA56D
2K-BIT SERIAL EEPROM WITH MICROWIRE INTEFACE
(compatible to САТ93С56 Catalyst)
DESCRIPTION The IN93LC56 is a Electric erasable programmable ROM (EEPROM) memory data capacity 2K (256x8 or 128x16) with 3-wire interface. There are 3 modification of ICs A: ICs IN93AA56AD/AN are 8 bits registers (256х8) - ORG pin not used B: ICs IN93AA56BD/BN are 16 bits registers (128х16) - ORG pin not used C: ICs IN93AA56CN/CD are configured as either registers of 8 bits (ORG pin at GND) or 16 bits (ORG pin at VCC, or not connected). Each register can be written (or read) serially by using the DI (or DO) pin. The ICs is purposed for reading, writing & nonvolatile data storage in electronic units with 3-wire interface. ICs can be used in TV-sets, telecom equipment & consumer electronic devices.
