DS21794E-page 1 93AA56A/B/C, 93LC56A/B/C, 93C56A/B/C Device Selection Table Features: • Low-power CMOS technology • ORG pin to select word size for ‘56C’ version • 256 x 8-bit organization ‘A’ ver. devices (no ORG) • 128 x 16-bit organization ‘B’ ver. devices (no ORG) • Self-timed erase/write cycles (including auto-erase) • Automatic ERAL before WRAL • Power-on/off data protection circuitry • Industry standard 3-wire serial I/O • Device Status signal (Ready/Busy) • Sequential read function • 1,000,000 E/W cycles • Data retention > 200 years • Pb-free and RoHS compliant • Temperature ranges supported: Pin Function Table 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.
