Description

The Microchip Technology Inc. 93XX66A/B/C( 93LC66A-I/ST ) devices are 4K bit low voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable devices such as the 93AA66C, 93LC66C or 93C66C are dependent upon external logic levels driving the ORG pin to set word size. For dedicated 8-bit communication, the 93AA66A, 93LC66A or 93C66A devices are available, while the 93AA66B, 93LC66B and 93C66B devices provide dedicated 16-bit communication. Advanced CMOS technology makes these devices ideal for low power, non-volatile 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, and 8-lead TSSOP. Pb-free (Pure Matte Sn) finish is also available. 93LC66A-I/ST Features • Low-power CMOS technology• ORG pin to select word size for ‘66C version• 512 x 8-bit organization ‘A’ ver. devices (no ORG)• 256 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
