Word-selectable devices such as 256 x 8-bit organization A ver. devices (no ORG) the 93AA56C, 93LC56C or 93C56C are dependent 128 x 16-bit organization B ver. devices (no upon external logic levels driving the ORG pin to set ORG) word size. For dedicated 8-bit communication, the Self-timed erase/write cycles (including 93XX56A devices are available, while the 93XX56B auto-erase) devices provide dedicated 16-bit communication. Automatic ERAL before WRAL Advanced CMOS technology makes these devices ideal for low-power, nonvolatile memory applications. Power-on/off data protection circuitry The entire 93XX Series is available in standard Industry standard 3-wire serial I/O packages including 8-lead PDIP and SOIC, and Device Status signal (Ready/Busy) advanced packaging including 8-lead MSOP, 6-lead Sequential read function SOT-23, 8-lead 2x3 DFN and 8-lead TSSOP. All 1,000,000 E/W cycles packages are Pb-free and RoHS compliant. Data retention > 200 years Pb-free and RoHS compliant Temperature ranges supported: - Industrial (I) -40C to +85C - Automotive (E) -40C to +125C Pin Function Table Name Function CS Chip Select CLK Serial Data Clock DI Serial Data Input DO Serial Data Output SS Ground V NC No internal connection ORG Memory Configuration CC Power Supply V 2007 Microchip Technology Inc.
