C8051F52x/F53x
20. Device Specific Behavior
This chapter contains behavioral differences between the silicon revisions of C8051F52x/52xA/F53x/53xA
devices.
These differences do not affect the functionality or performance of most systems and are described below.
20.1. Device Identification
The Part Number Identifier on the top side of the device package can be used for decoding device
information. The first character of the trace code identifies the silicon revision. On C8051F52x-C/53x-C
devices, the trace code (second line on the TSSOP-20 and DFN-10 packages; third line on the QFN-20
package) will begin with the letter "C". The "A" suffix at the end of the part number such as "C8051F530A"
is only present on Revision B devices. All other revisions do not include this suffix. Figures 20.1, 20.2, and
20.3 show how to find the part number on the top side of the device package.
