Product details
Overview
MSP430G2132IPW14 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 1 kB Flash, 128 B RAM, a 10-bit 200-ksps ADC with internal reference and autoscan, one 16-bit Timer_A with three capture/compare registers, USI supporting SPI and I²C, and up to 8 capacitive-touch enabled I/O pins - deployed in battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430G2132IPW14 datasheet, MSP430G2132IPW14 pinout, MSP430G2132IPW14 application, or MSP430G2132IPW14 equivalent, key selection criteria include its 14-pin TSSOP package, 1.8–3.6 V supply range, sub-1 µs wake-up from standby, integrated brownout detection, and Spy-Bi-Wire debug interface without external programming voltage.
Technical Context
The MSP430G2132IPW14 implements a 16-bit CPU with seven addressing modes and 51 instructions, paired with a basic clock module offering DCO (calibrated at 1/8/12/16 MHz), LF oscillator, and 32-kHz crystal support. Its ADC10 module includes internal 1.5 V/2.5 V reference, sample-and-hold, and DMA-assisted data transfer.
Power management uses five software-selectable low-power modes (LPM0–LPM4); active mode draws 220 µA at 1 MHz/2.2 V, standby consumes 0.5 µA, and off mode retains RAM at 0.1 µA. The USI supports master/slave SPI and I²C with programmable clock polarity and phase.

FAQ
What is the maximum ADC sampling rate supported by the MSP430G2132IPW14?
The MSP430G2132IPW14 supports a maximum ADC10 sampling rate of 200 ksps. This is achievable when using the internal oscillator as the ADC10CLK source and configuring the sample-and-hold time for minimum acquisition cycles. The actual sustained rate depends on system clock configuration, reference selection, and software overhead - but the hardware limit remains 200 ksps per the SLAS723H datasheet.
Does the MSP430G2132IPW14 support hardware UART communication?
No, the MSP430G2132IPW14 does not include a dedicated UART peripheral. It features a Universal Serial Interface (USI) module that supports SPI and I²C protocols only. UART functionality must be implemented in software using Timer_A and GPIO pins - a common practice in MSP430G2x32 designs where low-speed serial debug or host communication is required.
Can the MSP430G2132IPW14 operate from a 1.8 V supply while running at 16 MHz?
No. According to the SLAS723H datasheet, the MSP430G2132IPW14 requires a minimum supply voltage of 2.2 V to sustain 16 MHz DCO operation. At 1.8 V, the maximum guaranteed system frequency is 1 MHz. Operating above the specified voltage-frequency envelope risks timing violations and functional failure, even if the device appears to run intermittently.
How many I/O pins on the MSP430G2132IPW14 support capacitive-touch sensing?
Eight I/O pins on the MSP430G2132IPW14 support capacitive-touch sensing: all eight bits of Port 1 (P1.0 through P1.7). Each pin has an individually programmable pin-oscillator enable bit (P1SEL.x), allowing any subset to be configured for touch operation without affecting other GPIO functions - a feature confirmed in the "Digital I/O" section of SLAS723H.
Is the MSP430G2132IPW14 pin-compatible with the MSP430G2432IPW14?
Yes, the MSP430G2132IPW14 is pin-compatible with the MSP430G2432IPW14. Both devices use the identical 14-pin TSSOP (PW14) package and share identical pin functions and electrical characteristics per Table 2 of SLAS723H. The primary difference lies in Flash size (1 kB vs. 8 kB) and RAM (128 B vs. 256 B); all peripherals, I/O mapping, and debug interfaces match exactly.
