MSP430F2122IRHBT   

16-bit ultra-low-power microcontroller with 4kB flash, 512B of RAM, 10-bit ADC and USCI

illustrate   The Texas Instruments MSP430 ultra-low-power microcontroller family includes multiple devices with peripheral sets for a variety of different applications. The architecture, with 5 low-power modes combined, is optimized to enable portablemeasurement applications to extend battery life. The device features a powerful 16-bit RISC CPU, 16-bit registers, and contributes to maximum code efficiency generators. The digitally controlled oscillator (DCO) allows wake-up from low-power mode in less than 1 microsecond in active mode. The MSP430F21x2 series is a series of ultra-low-power microcontrollers with two built-in 16-bit timers, a fast 10-bit A/D converter integrated reference and data transfer controller (DTC), a comparator, built-in communication capabilities using a common serial communication interface, and up to 24 I/O pins.   characteristic   Low supply voltage range, 1.8 V to 3.6 V Ultra-low power consumption: Active mode: 250 microamperes at 1 MHz, 2.2 V is also available Standby mode: 0.7 microamps Off mode (RAM hold): 0.1 microamperes Ultra-fast wake-up standby mode less than 1μs 16-bit RISC architecture, 62.5 ns instruction cycle time Basic Clock Module Configuration: Quad calibration frequency up to 16 MHz with internal frequency± 1% Very low power low frequency oscillator inside 32 - kHz crystal Crystals with high frequencies up to 16 MHz Resonator External digital clock source External resistance 16-bit 3-way capture Timer0_A3/comparison register 16-bit Timer1_A2 two capture/compare registers On-chip analog signals are still comparative features of slope analog-to-digital (A/D) conversion The 10-bit A/D converter at 200 ksps has an internal reference, sample and hold, auto-scan and data transfer controller Universal serial communication interface
