Description
The Microchip Technology Inc. 93XX66A/B/C devices
are 4K bit low voltage serial Electrically Erasable
PROMs (EEPROM). Word-selectable devices such as
the 93AA66C, 93LC66C or 93C66C are dependent
upon external logic levels driving the ORG pin to set
word size. For dedicated 8-bit communication, the
93AA66A, 93LC66A or 93C66A devices are available,
while the 93AA66B, 93LC66B and 93C66B devices
provide dedicated 16-bit communication. Advanced
CMOS technology makes these devices ideal for low
power, non-volatile memory applications. The entire
93XX Series is available in standard packages includ-
ing 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.

Can F28027 use CCS3.3?
I recently used CCS3.3 to create a new F28027 project. Why does it always remind me of an error? The method of creating a project is the same as 2812. What is the reason for this?...
