93C46BT/ST [Microchip]

The Microchip Technology Inc. 93XX46A/B/C devices are 1-Kbit low-voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable devices such as the 93AA46C, 93LC46C or 93C46C are dependent upon external logic levels driving the ORG pin to set word size. For dedicated 8-bit communication, the 93AA46A, 93LC46A or 93C46A devices are available, while the 93AA46B, 93LC46B and 93C46B devices provide dedicated 16-bit communication. Advanced CMOS technology makes these devices ideal for low-power, nonvolatile memory applications. Features include Low-Power CMOS Technology, Self-Timed Erase/Write Cycles, Automatic Erase All (ERAL) Before Write All (WRAL), Power-On/Off Data Protection Circuitry, Industry Standard 3-Wire Serial I/O, Device Status Signal (Ready/Busy), Sequential Read Function, High Reliability with 1,000,000 erase/write cycles endurance, Data Retention > 200 years, ESD protection > 4,000V, RoHS Compliant, and Automotive AEC-Q100 Qualified.
