Note:

The CC2431 and the CC2430 are pin compatible, and the MCU and RF parts of the

CC2430-F128 are identical to the CC2431 except the Location Engine. This data sheet

complements the CC2430 data sheet with a description of the Location Engine. For

complete information about the CC2431, please refer to the CC2430 data sheet in

addition to this data sheet.
