Product details
Overview
MSP430G2153IPW20 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 16 KB flash, 256 B RAM, a 10-bit 200-ksps ADC with internal reference and autoscan, two 16-bit Timer_A modules with three capture/compare registers each, and USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C) interfaces. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2153IPW20 datasheet, MSP430G2153IPW20 pinout, MSP430G2153IPW20 application, or MSP430G2153IPW20 equivalent, key selection criteria include its 20-pin TSSOP package, ADC10 availability (confirmed for G2x53 family), Spy-Bi-Wire debug interface, five low-power modes with sub-1-µs wake-up, and integrated comparator for analog signal conditioning.
Technical Context
The MSP430G2153IPW20 implements a 16-bit CPU with constant generators and seven addressing modes, executing instructions in one MCLK cycle. Its clock system integrates a digitally controlled oscillator (DCO), 32-kHz crystal support, and internal LF oscillator - enabling stable operation across supply voltages from 1.8 V to 3.6 V with calibrated DCO frequencies up to 16 MHz.
Peripherals are memory-mapped and accessible via all CPU instructions. The device supports interrupt-driven operation with 18 maskable sources including ADC10IFG, USCI_A0/B0 RX/TX flags, Timer_A CCIFG/TAIFG, and port P1/P2 IFG registers - all routed through dedicated vectors in the 0xFFFE–0xFFC0 interrupt vector table.
