Description:
The Microchip Technology Inc. 93XX46A/B/C devices
are 1Kbit 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 includ-
ing 8-lead PDIP and SOIC, and advanced packaging
including 8-lead MSOP, 6-lead SOT-23, 8-lead
2x3 DFN/TDFN and 8-lead TSSOP. All packages are
Pb-free (Matte Tin) finish.

† NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to
the device. This is a stress rating only and functional operation of the device at those or any other conditions
above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.
