        cc2652r device has very low active rf and micro controller (mcu) current, sleep current less than 1 μa, and up to 80kb ram retention capacity protected by parity, which can provide excellent battery life and support long-term operation in energy collection applications relying on small button batteries. rf-bm-2652b1, a bluetooth module with cc2652r chip, is now available in shenzhen xinchida technology co., ltd., which can meet the demand of scene application in industrial field, for example.

        the cc2652r device combines a flexible ultra-low power rf transceiver with a powerful 48 mhz arm ® cortex ® - m4f cpu on a platform supporting multiple physical layers and rf standards. the dedicated radio controller (arm ® cortex ® - m0) can handle low-level rf protocol commands stored in rom or ram, thus ensuring ultra-low power consumption and excellent flexibility. the low power consumption of cc2652r device will not affect the rf performance. cc2652r device has excellent sensitivity and durability.

        with a programmable, autonomous, ultra-low power sensor controller cpu with 4kb program and data sram memory, the sensor can be processed with very low power consumption. the sensor controller with fast wake-up and ultra-low power consumption 2mhz mode is specially designed for sampling, caching and processing of analog and digital sensor data, so mcu system can maximize sleep time and reduce working power consumption. rf-bm-2652b1, a bluetooth module with cc2652r chip, can fully meet the needs of low-power scenarios.
