Description
The Microchip Technology Inc. 93XX76A/B/C devices
are 8K bit, 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. For
dedicated 8-bit communication, the 93XX76A devices
are available, while the 93XX76B devices provide
dedicated 16-bit communication, available on SOT-23
devices only. 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 including 8-lead MSOP, 6-lead SOT-23,
and 8-lead TSSOP. Pb-free (Pure Matte Sn) finish is
also available.
