Frequently Asked Questions
What RF standard and frequency band does CC2640F128RHB support for wireless connectivity?
CC2640F128RHB supports Bluetooth Low Energy (BLE) 4.2 operating in the 2.4 GHz ISM band with an integrated RF front-end including the LNA, PA, and RF switch. The single-chip design eliminates the need for an external RF amplifier or balun in most designs, reducing BOM and antenna-matching complexity. Typical output power reaches 5 dBm with a receive sensitivity of approximately -97 dBm, enabling line-of-sight ranges exceeding 100 meters.
How does CC2640F128RHB's sensor controller reduce power consumption in IoT applications?
CC2640F128RHB includes a dedicated sensor controller that can autonomously sample ADC inputs, interface with SPI or I2C peripherals, and wake the main Cortex-M3 core only when a threshold is crossed, operating at under 1 µA in standby. This architecture allows the main CPU to remain in deep sleep for long intervals while the sensor controller monitors environmental conditions at a fraction of active-mode power. A coin-cell battery at 200mAh capacity can sustain typical IoT sensor nodes for 2 to 5 years using this duty-cycling approach.
Is CC2640F128RHB still recommended for new designs, and what should replace it?
CC2640F128RHB carries a YTEOL value of 0, indicating it is at or near end-of-life and is not recommended for new designs. Texas Instruments recommends the CC2640R2F or CC2651 family as successors, offering BLE 5.0 support, larger memory, and improved power consumption figures. Existing designs using CC2640F128RHB should evaluate the successor part's footprint and stack compatibility before transitioning to avoid significant re-qualification effort.
Which wearable and health monitoring designs benefit most from CC2640F128RHB?
Wearable fitness bands, continuous glucose monitors, and pulse oximeters benefit from CC2640F128RHB because the 32-pin QFN package fits in tight wrist-worn enclosures while the BLE 4.2 radio connects to smartphones for data sync. The ARM Cortex-M3 at 48 MHz provides enough computation for real-time sensor fusion algorithms such as step counting and heart-rate detection from raw accelerometer and PPG data. Its 128 KB Flash holds both the sensor application and the TI BLE-Stack without external memory.
