2.3.1 CC2662R-Q1

The CC2662R-Q1 SimpleLink™ Wireless MCU contains an Arm® Cortex®-M4F system CPU, which runs the application and the higher layers of the Wireless BMS protocol stack.

The system CPU is the foundation of a high-performance, low-cost platform that meets the system requirements of minimal memory implementation, and low-power consumption, while delivering outstanding computational performance and exceptional system response to interrupts.

The highlighted features of this device include:

  • Support for TI's SimpleLink™ wireless BMS (WBMS) protocol for robust, low latency, and high throughput communication
  • Functional Safety Quality-Managed classification including TI quality-managed development process and forthcoming functional safety FIT rate calculation, FMEDA, and functional-safety documentation
  • AEC-Q100 qualified for Grade 2 temperature range (–40°C to +105°C) and is offered in a 7mm × 7mm VQFN package with wettable flanks
  • Low standby current of 0.94μA with full RAM retention
  • Excellent radio link budget of 97dBm
