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. 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/TDFN and 8-
lead TSSOP. All packages are Pb-free (Matte Tin)
finish.
