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.
