Product introduction：As a member of BT-SIG, Texas Instruments (TI) introduced CC254x series of SOC low-power Bluetooth transceiver. With classical 51 kernel inside, its most prominent features are rich periphery (including 21 IO, UART, SPI, USB2.0, PWM, ADC, analog comparator, op-amp), super wide working voltage (2v – 3.6v), extreme low energy consumption (<0.4μA), and very short wake-up delay (4μs)
