MSP430G2302IRSA16R vs MSP430G2402IRSA16R vs MSP430G2302IPW14 Comparison

DESCRIPTION The Texas Instruments MSP430™ family of ultra-low-power microcontrollers consist of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with five 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 wake-up from low-power modes to active mode in less than 1 µs. FEATURES • Low Supply Voltage Range: 1.8 V to 3.6 V • Ultra-Low Power Consumption – Active Mode: 220 µA at 1 MHz, 2.2 V – Standby Mode: 0.5 µA – Off Mode (RAM Retention): 0.1 µA • Five Power-Saving Modes • Ultra-Fast Wake-Up From Standby Mode in Less Than 1 µs • 16-Bit RISC Architecture, 62.5-ns Instruction Cycle Time • Basic Clock Module Configurations – Internal Frequencies up to 16 MHz With Four Calibrated Frequencies – Internal Very-Low-Power Low-Frequency (LF) Oscillator – 32-kHz Crystal – External Digital Clock Source • One 16-Bit Timer_A With Three Capture/Compare Registers • Up to 16 Touch-Sense Enabled I/O Pins • Universal Serial Interface (USI) Supporting SPI and I2C • 10-Bit 200-ksps Analog-to-Digital (A/D) Converter With Internal Reference, Sample-and-Hold, and Autoscan (MSP430G2x32 Only) • Brownout Detector • Serial Onboard Programming, No External Programming Voltage Needed, Programmable Code Protection by Security Fuse • On-Chip Emulation Logic With Spy-Bi-Wire Interface • Family Members are Summarized in Table 1 • Package Options – TSSOP: 14 Pin, 20 Pin – PDIP: 20 Pin – QFN: 16 Pin • For Complete Module Descriptions, See the MSP430x2xx Family User’ s Guide (SLAU144)
