28. Revision-Specific Behavior
C8051F85x/86x Revision B devices have differences from Revision C devices:
Temperature Sensor offset and slope
Flash endurance
Latch-up performance
Unique Identifier
28.1. Revision Identification
The Lot ID Code on the top side of the device package can be used for decoding device revision
information. Figure 28.1, Figure 28.2, and Figure 28.3 show how to find the Lot ID Code on the top side of
the device package.
Firmware can distinguish between a Revision B and Revision C device using the value of the REVID
register described in “Device Identification and Unique Identifier” on page 64.
