LP-EM-CC2340R5

The Code Composer Studio™ IDE is a complete integrated suite that enables developers to create and debug applications of all Texas Instruments Embedded Processors (Sitara, DSP, Automotive, Keystone), Microcontrollers (SimpleLink™, C2000 Digital Control, MSP430, TM4C, Hercules), as well as Digital Power (UCD) and Programmable Gain Amplifier (PGA) devices.

CCS v20 is TI’s next generation Integrated Development Environment (IDE) based on Theia IDE framework. CCS v20.0.2 uses a modified version of the Theia-IDE framework and offers a user experience similar to Visual Studio Code™.

• Installation instructions and User's Guide
• Windows 32bit is not supported with CCSv20.
• XDS510 class debug probes are not supported with CCSv20.

The SimpleLink™ Low Power F3 Software Development Kit (SDK) delivers components that enable engineers to develop applications on the Texas Instruments SimpleLink CC23xx family of wireless microcontrollers (MCUs). This software toolkit provides a cohesive and consistent software experience for all SimpleLink CC23xx wireless MCU users by packaging essential software components, such as:

• Bluetooth® Low Energy (BLE) protocol stack

• Zigbee® protocol stack supporting low power wireless mesh networks

• Proprietary RF layer

• TI Drivers

All of the above are provided in one easy-to-use software package along with example applications and documentation.

The SimpleLink MCU portfolio offers a single development environment that delivers flexible hardware, software, and tool options for customers developing wired and wireless applications. With 100 percent code reuse across host MCUs, Wi-Fi™, Bluetooth Low Energy, Sub-1GHz devices and more, choose the MCU or connectivity standard that fits your design. A one-time investment with the SimpleLink software development kit allows you to reuse often, opening the door to create unlimited applications.

LAES & HSM Limitations

The CC27xx family of devices now include a Hardware Security Module (HSM) for cryptographic and key storage features.

For crypto drivers that support the HSM and LAES, a failure in the HSM bootup process will be cached in the driver’s handle. If the user attempts to perform an HSM operation later, it will return an error due to the cached initialization error. LAES operations would continue to function without issue in that case.

For drivers that support running operations on both hardware accelerators, a switch has been implemented so that the driver knows which engine to use to execute the operation on. This switch is part of the cryptography operation’s key. The key encoding associated with each key that is included as part of the user-provided data to the driver is where the user can specify which hardware accelerator to use.

• To leverage the HSM hardware accelerator, the user has to call ‘CryptoKeyPlaintextHSM_initKey(..)’ API and pass in the plaintext key as well as the key length.

• To leverage the LAES hardware accelerator, the user has to call ‘CryptoKeyPlaintext_initKey()(..)’ API and pass in the plaintext key as well as the key length.

NOTE:

• Mass erasing the CC27xx without retaining protected sectors will result in the erasure of the HSM firmware. Please see the Quick Start Guide: Build your first program for the CC23xx or CC27xx device on how to re-flash the HSM firmware.
