MSP430G2231IPW14R  

MSP430G2x21, MSP430G2x31 mixed-signal microprocessor

illustrate   Texas Instruments' MSP430 ultra-low-power microcontroller family includes multiple devices with peripheral sets for a variety of different applications. The architecture, with five low-power modes combined, is optimized to achieve extended battery life in portable measurement applications. 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 active mode in less than 1 microsecond. The MSP430G2x21/31 series is an ultra-low-power mixed-signal microcontroller with a built-in 16-bit timer and ten I/O pins. The MSP430G2x31 for family members has a 10-bit A/D converter and built-in communication capability using (SPI or I2C) synchronization protocols.   characteristic   Low supply voltage range: 1.8 V to 3.6 V Ultra-low power consumption Active mode: 220 microamperes at 1 MHz, 2.2 V is also available Standby mode: 0.5 microamps Off mode (RAM hold): 0.1 microamperes There are 5 power-saving modes Ultra-fast wake-up from standby mode in less than 1 microsecond 16-bit RISC architecture with 62.5 ns instruction cycle time Basic clock module configuration The internal frequency is calibrated with up to 16 MHz Internal very low power low frequency (LF) oscillator 32 - kHz crystal External digital clock source 16-bit Timer_A two capture/comparison registers The Universal Serial Interface (USI) supports SPI and I2C Power loss detector The A/D converter at 10-bit 200 ksps has internal reference, sample and hold, and AutoScan On-board serial programming eliminates the need for external programming voltages, and programmable safety fuse code protection The on-chip spy blue line interface simulation logic Available in 14-pin plastic miniature package thin-film package (TSSOP), 14-pin plastic dual-in-line package (PDIP package), and 16-pin QFN
