Texas Instruments has introduced two low-power, short-range wireless connectivity solutions for consumer medical, mobile accessories, and sports and wellness applications. The CC2540 single-mode Bluetooth Low Energy (LE) system-on-chip and the CC257x ANT network processor can reportedly enable target applications to operate on a coin cell for more than a year.
The CC2540 integrates Bluetooth LE controller, host and application in a 6 x 6 mm package. The Flash-based device’s firmware can be updated in the field and data can be stored on-chip, increasing flexibility for developers. Its RF performance provides a link budget for long range (up to +97 dB) and coexistence with other 2,4 GHz devices.
The CC257x boasts a link budget of +95 dB and excellent selectivity for coexistence with other 2,4 GHz devices. Integration of ANT-FS function and AES encryption support reduces components and bill-of-materials (BOM) cost.
