The Microchip Technology Inc. 93XX46A/B/C devices
are 1Kbit low-voltage serial Electrically Erasable
PROMs (EEPROM). Word-able devices such as
the 93AA46C, 93LC46C93C46C are dependent
upon external logic levels driving the ORG pin to set
word size. For dedicated 8-bit communication, the
93AA46A, 93LC46A93C46A devices are available,
while the 93AA46B, 93LC46B93C46B devices
provide dedicated 16-bit communication. Advanced
CMOS technology makes these devices ideal for lowpower, nonvolatile memory applications. The entire
93XX Series is available in standard packages including 8-lead PDIPSOIC,advanced packaging
including 8-lead MSOP, 6-lead SOT-23, 8-lead
2x3 DFN/TDFN8-lead TSSOP. All packages are
Pb-free (Matte Tin) finish.
