3 Description

The SimpleLink™ CC2755x20 family of devices are 2.4GHz wireless microcontrollers (MCUs), targeting Bluetooth® Low Energy (6.0 and the upcoming versions), Zigbee (4.0 and the upcoming versions), Matter (1.5 and the upcoming versions), Thread (1.4 and the upcoming versions), and other 2.4GHz applications. These devices are optimized for low-power wireless communication with Over the Air Download (OAD) support in building automation (wireless sensors, lighting control, beacons), appliances, asset tracking, medical, and personal electronics (toys, HID, stylus pens) markets. Highlighted features of this device include:

  • Support for features in Bluetooth® 6.x and earlier versions:
    • LE Coded PHYs (Long Range), LE 2Mbit PHY (high speed), advertising extensions, multiple advertisement sets, CSA#2, as well as backward compatibility with earlier Bluetooth® Low Energy specifications
  • Supports an Algorithm Processing Unit (APU) to enable high accuracy, low cost, and secure phase-based ranging mechanism for distance estimation
    • APU enables latency and power-efficient execution of distance-ranging signal processing algorithms, including FFT and super-resolution complex algorithms like MUltiple SIgnal Classification (MUSIC)
  • Arm® Custom Datapath Extension (CDE) instruction support for machine learning acceleration
  • Matter stack available on https://github.com/TexasInstruments/matter
  • Thread protocol stack available on https://github.com/TexasInstruments/ot-ti
  • Fully qualified Bluetooth® software protocol stack included with the SimpleLink™ Low Power F3 Software Development Kit (SDK)
  • Zigbee® protocol stack support in the SimpleLink™ Low Power F3 Software Development Kit (SDK)
  • Advanced security features for connected wireless MCUs:
    • An isolated HSM environment with a dedicated controller handling accelerated cryptographic and random number generation operations
    • Secure boot and firmware updates with the root of trust enabled by an immutable system ROM
    • Arm® Cortex M33 TrustZone-M based trusted execution environment support
    • Secure key storage support with HSM and TrustZone-M
    • Hardware fault sensors to mitigate low-cost, low-effort, non-invasive physical attack threats like voltage glitch injection
    • Dedicated AES-128 HW accelerator for handling timing-critical link-layer encryption/decryption operations
  • Ultra-low standby current with full 288KB SRAM retention and RTC operation that enables significant battery life extension, especially for applications with longer sleep intervals
  • Extended temperature support with very low standby current
  • Integrated balun and integrated RF switch to support both transmit and receive operations on the same RF pin, even at +20dBm transmit power; thereby, enabling a reduced bill-of-material (BOM) board layout
  • Excellent radio sensitivity and robustness (selectivity and blocking) performance for Bluetooth® Low Energy and IEEE 802.15.4

The CC2755x20 devices are part of the SimpleLink™ MCU platform, which consists of Wi-Fi®, Bluetooth® Low Energy, Thread, Zigbee, Sub1GHz MCUs, and host MCUs that all share a common, easy-to-use development environment with a single core software development kit (SDK) and a rich toolset. A one-time integration of the SimpleLink™ platform enables you to add any combination of the portfolio’s devices into your design, allowing 100 percent code reuse when your design requirements change.
