IN93AA66N

IN93AA66N, IN93AA66D 4K-BIT SERIAL EEPROM WITH MICROWIRE INTEFACE (compatible to САТ93С66 Catalyst) DESCRIPTION The IN93LC66 is a Electric erasable programmable ROM (EEPROM) memory data capacity 4K (512x8 or 256x16) with 3-wire interface. There are 3 modification of ICs A: ICs IN93AA66AD/AN are 8 bits registers (512х8) - ORG pin not used B: ICs IN93AA66BD/BN are 16 bits registers (256х16) - ORG pin not used C: ICs IN93AA66CN/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. ICs can be used in TV-sets, telecom equipment & consumer electronic devices. FEATURES ■ 100 year data (4K) retention for Ta=25oC; ■ Single power supply source (VСС = 1,8 V – 6,0 V); ■ Build-in voltage multiplier; ■ Serial I/O bus; ■ Autoincrement of address word; ■ Self-timed write cycle; ■ 1,000,000 Program/erase cycles; ■ Power-up internal logic setup; ■ Read cycles quantity are not limited; ■ Low power consumption; ■ Operating temperature range -40 … +85 oC.
