Description:

The Microchip Technology Inc. 93XX46A/B/C devices

are 1K bit low-voltage serial Electrically Erasable

PROMs (EEPROM). Word-selectable devices such as

the 93AA46C, 93LC46C or 93C46C are dependent

upon external logic levels driving the ORG pin to set

word size. For dedicated 8-bit communication, the

93AA46A, 93LC46A or 93C46A devices are available,

while the 93AA46B, 93LC46B and 93C46B 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. Pb-free (Pure Matte Sn) finish

is also available.
