Pin Function Table

Description:

The Microchip Technology Inc. 93XX66A/B/C devices

are 4Kbit 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

93XX66A devices are available, while the 93XX66B

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 (Matte Tin) finish.
