The Texas Instruments MSP430 family of ultralow-power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with extensive low-power modes, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active mode in less than 5 µs. MSP430BT5190 is a microcontroller configuration with three 16-bit timers, a high-performance 12-bit analog-to-digital converter (ADC), four universal serial communication interfaces (USCIs), a hardware multiplier, DMA, a real-time clock module with alarm capabilities, and 87 I/O pins. The MSP430BT5190 microcontroller is designed for commercial use with TI"s CC2560 based Bluetooth solutions in conjunction with Mindtree"s Ethermind Bluetooth stack and Serial Port Profile (SPP). This MSP430BT5190+CC2560 Bluetooth platform is ideal for applications that need a wireless serial link for cable replacement, such as remote controls, thermostats, smart metering, blood glucose meters, pulseoximeters, and many others.
