This technical reference manual provides information about how to use the CC13x2x7 and CC26x2x7SimpleLink™ ultra-low power wireless microcontroller (MCU). The CC2652x7 and the CC13x2x7 device platforms share the same MCU architecture and most of the peripherals. The radio in the CC2652x7 device operates in the 2.4 GHz ISM frequency band, while the radio in the CC1312x7 device is designed for use in the Sub-1 GHz frequency bands. The CC1352x7 device is a multi-band wireless MCU and can operate both in the Sub-1 GHz and 2.4 GHz bands. This document covers the whole platform of devices, so refer to the individual device data sheets for supported modules and features.

This document is organized into sections that correspond to each major feature; it explains the features and functionality of each module and how to use them. For each feature, references are given to the driver documentation of the corresponding operating systems. Driver documentation does not contain performance characteristics for the device or modules, which are instead in the corresponding device data sheets. This manual is intended for system software developers, hardware designers, and application developers.

The CC13x2x7 and CC26x2x7 device platform includes both 2.4 GHz (CC2652x7 and CC1352x7) and Sub-1 GHz (CC1312x7) radios along with a variety of different memory sizes, peripherals, and package options. All devices are centered around an Arm®Cortex®-M4F series processor that handles the application layer and protocol stack, as well as an autonomous radio core centered around an Arm^® Cortex^®-M0 processor that handles all the low-level radio control and processing. Network processor options are available.

The availability of a wide range of different radio and MCU system combinations makes these device families very well suited for almost any low-power RF node implementation.

The naming convention applied for a call consists of:

• For a register call: <Module name>.<Register name>; for example: UART.UASR
• For a bit field call:
  • <Module name>.<Register name>[End:Start] <Field name> field; for example, UART.UASR[4:0] SPEED bit field
  • <Field name> field <Module name>.<Register name>[End:Start]; for example, SPEED bit field UART.UASR[4:0]
• For a bit call:
  • <Module name>.<Register name>[pos] <Bit name> bit; for example, UART.UASR[5] BIT_BY_CHAR bit
  • <Bit name> bit <Module name>.<Register name>[pos]; for example, BIT_BY_CHAR bit UART.UASR[5]
