Description:
The Microchip Technology Inc. 93XX76A/B/C devices
are 8Kbit, low-voltage, serial Electrically Erasable
PROMs (EEPROM). Word-selectable devices such as
the 93XX76C are dependent upon external logic levels
driving the ORG pin to set word size. The 93XX76A
devices provide dedicated 8-bit memory organization,
while the 93XX76B devices provide dedicated 16-bit
memory organization. A Program Enable (PE) pin allows
the user to write-protect the entire memory array.
Advanced CMOS technology makes these devices ideal
for low-power, nonvolatile memory applications. The
93XX Series is available in standard packages including
8-lead PDIP and SOIC, and advanced packaging includ-
ing 8-lead MSOP, 6-lead SOT-23, 8-lead 2x3 DFN/
TDFN and 8-lead TSSOP. All packages are Pb-free
(Matte Tin) finish.
