93LC56B-I/SNG Datasheet PDF - Microchip

●Description

●The Microchip Technology Inc. 93XX56A/B/C devices are 2K bit low voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable devices such as the 93AA56C, 93LC56C or 93C56C are dependent upon external logic levels driving the ORG pin to set word size. For dedicated 8-bit communication, the 93AA56A, 93LC56A or 93C56A devices are available, while the 93AA56B, 93LC56B and 93C56B devices provide dedicated 16-bit communication. Advanced CMOS technology makes these devices ideal for low power, nonvolatile memory applications.
