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.
