Description:
The Microchip Technology Inc. 93XX86A/B/C devices
are 16K bit low-voltage serial Electrically Erasable
PROMs (EEPROM). Word-selectable devices such as
the 93XX86C are dependent upon external logic
levels driving the ORG pin to set word size. In the
SOT-23 package, the 93XX86A devices provide
dedicated 8-bit memory organization, while the
93XX86B 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 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 available.
