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 93XX56A devices are available， while the 93XX56B devices provide dedicated 16-bit communication. Advanced CMOS technology makes these devices ideal for low-power， nonvolatile memory applications. The entire 93XX Series is available in standard packages including 8-lead PDIP and SOIC， and advanced packaging including 8-lead MSOP， 6-lead SOT-23， 8-lead 2x3 DFN and 8-lead TSSOP. All packages are Pb-free and RoHS compliant.
