IN93LC46N
IN93LC46N is 1K-BIT SERIAL EEPROM manufactured by Integral.
DESCRIPTION
The IN93LC46 is a Electric erasable programmable ROM (EEPROM) memory data capacity 1K (128x8 or 64x16) with 3-wire interface. There are 3 modification of ICs A: ICs IN93AA(LC)46AD/AN are 8 bits registers (128х8)
- ORG pin is not used B: ICs IN93AA(LC)46BD/BN are 16 bits registers (64х16)
- ORG pin is not used C: ICs IN93AA(LC)46CN/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, tele equipment & consumer electronic devices.
