21. Revision Specific Behavior
This chapter contains behavioral differences between C8051F52x/F53x "REV_A" and “REV_B" or later
devices.
These differences do not affect the functionality or performance of most systems and are described below.
21.1. Revision Identification
The Lot ID Code on the top side of the device package can be used for decoding device revision informa-
tion. On C8051F52x and C8051F53x devices the revision letter is the first letter of the Lot ID Code.
Figures 21.1, 21.2, and 21.3 show how to find the Lot ID Code on the top side of the device package.
