Description

The Microchip Technology Inc. 93XX66A/B/C 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 includ-

ing 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.
