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.
