Texas Instruments has added two devices to its scalable SimpleLink Bluetooth Low Energy microcontroller line-up. The devices offer a single-chip hardware and unified software solution with an ARM Cortex-M3 based MCU, automatic power management, Bluetooth-compliant radio and a low-power sensor controller.

The SimpleLink CC2640R2F wireless MCU comes in a 2.7mm x 2.7mm chip-scale package (WCSP) option that is less than half the size of TI's smallest 4mmm x 4mm QFN package, yet still delivers the longest range with the lowest power consumption, according to the company. The new CC2640R2F is ready for the Bluetooth 5 core specification for applications in building automation, medical, commercial and industrial automation.

Meanwhile, the SimpleLink CC2640R2F-Q1 wireless MCU enables smartphone connectivity for car access including passive entry passive start (PEPS) and remote keyless entry (RKE), as well as emerging automotive use cases with AEC-Q100 qualification and Grade 2 temperature rating. Additionally, the CC2640R2F-Q1 device is offered in a wettable flank QFN package which helps reduce production line cost and increases reliability enabled by optical inspection of solder points.

These additions will ease reuse of projects across pin- and code-compatible ultra-low-power CC264x wireless MCUs, the company said.

The CC264x family is supported by a unified software and application development environment, royalty-free BLE-Stack software, Code Composer Studio integrated development environment (IDE), system software and interactive training materials.

The CC2640R2F wireless MCU is available in 2.7mm x 2.7mm WCSP and 4mm x 4mm, 5mm x 5mm and 7mm x7mm QFN packages starting at ₹135.99 ($2) in 1,000 unit volumes, while the CC2640R2F-Q1 wireless MCU is available in a 7mm x 7mm QFN package starting at ₹475.28 ($6.99) in 1,000 unit volumes.
