DS21797G-page 1 93AA86A/B/C, 93LC86A/B/C, 93C86A/B/C Device Selection Table Features: • Low-power CMOS technology • ORG pin to select word size for ‘86C’ version • 2048 x 8-bit organization ‘A’ devices (no ORG) • 1024 x 16-bit organization ‘B’ devices (no ORG) • Program Enable pin to write-protect the entire array (‘86C’ version only) • 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 • Temperature ranges supported: Pin Function Table Description: The Microchip Technology Inc. 93XX86A/B/C devices are 16K bit low-voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable devices such as the 93XX86C are dependent upon external logic levels driving the ORG pin to set word size. In the SOT-23 package, the 93XX86A devices provide dedicated 8-bit memory organization, while the 93XX86B devices provide dedicated 16-bit memory organization. A Program Enable (PE) pin allows the user to write-protect the entire memory array. 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. Pb-free (Pure Matte Sn) finish is available.
