Product details
Overview
MSP430F2132IPW from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 8KB Flash, 512B RAM, a 10-bit 200-ksps ADC with internal reference and DTC, two 16-bit timers (Timer0_A3 with three capture/compare registers, Timer1_A2 with two), USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I2C), and up to 24 I/O pins - deployed in portable battery-powered measurement systems requiring sub-1µs wake-up and µA-level standby current.
For engineers reviewing the MSP430F2132IPW datasheet, MSP430F2132IPW pinout, MSP430F2132IPW application, or MSP430F2132IPW equivalent, key selection criteria include its 0.7 µA standby mode, integrated comparator for slope A/D, calibrated DCO enabling <1 µs wake-up, and TSSOP-28 package compatibility with legacy MSP430F2xx designs.
Technical Context
The MSP430F2132IPW implements a 16-bit RISC CPU with seven addressing modes and constant generators for high code efficiency, paired with five software-selectable low-power modes (LPM0–LPM4) optimized for extended battery life. Its clock system integrates a digitally controlled oscillator (DCO) calibrated to ±1% at four frequencies up to 16 MHz, plus support for 32-kHz crystal, HF crystal, resonator, or external digital clock sources.
Peripherals are memory-mapped and accessible via all CPU instructions. The USCI modules provide protocol-flexible serial communication: USCI_A0 supports UART with auto-baudrate detection (LIN), IrDA encoding/decoding, and synchronous SPI; USCI_B0 supports SPI and I²C. The ADC10 includes sample-and-hold, autoscan, and a dedicated Data Transfer Controller (DTC) to offload CPU during conversion sequences.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2122IPW | 4KB Flash, 512B RAM, identical peripherals and pinout - lacks 4KB of program memory and associated info memory segment. | Suitable for simpler firmware with smaller code footprint; not viable for applications requiring >4KB code or calibration data storage. | Select when cost sensitivity outweighs future firmware scalability needs and memory headroom is confirmed. |
| MSP430G2553IPW | 16KB Flash, 512B RAM, same TSSOP-28 package, but enhanced USCI (dual UART), no LIN auto-baud, different DCO calibration granularity. | Better suited for UART-heavy designs; lacks factory-calibrated LIN support and has higher active current (270 µA @ 1 MHz). | Choose for new designs prioritizing larger code space and dual UART, accepting trade-offs in LIN compliance and ultra-low-power optimization. |
Compared with MSP430F2132IPW, MSP430F2122IPW offers identical low-power behavior and peripheral set at reduced memory capacity, while MSP430G2553IPW trades factory LIN tuning and sub-µA standby for greater Flash and dual UART flexibility - making MSP430F2132IPW optimal for LIN-connected, battery-limited sensor nodes requiring proven calibration and minimal quiescent draw.

FAQ
What is the maximum operating frequency of the MSP430F2132IPW?
The MSP430F2132IPW supports an internal digitally controlled oscillator (DCO) calibrated to four frequencies up to 16 MHz, with ±1% accuracy at 25°C and 3 V. External clock sources - including HF crystals up to 16 MHz, 32-kHz watch crystals, or resonators - can also drive the system clocks. The CPU executes instructions at the MCLK rate, and all timing-critical peripherals (ADC, timers, USCI) synchronize to derived clock signals (SMCLK, ACLK).
Does the MSP430F2132IPW support LIN bus communication?
Yes, the MSP430F2132IPW supports LIN 2.x communication via USCI_A0 configured in enhanced UART mode with hardware auto-baudrate detection. This feature enables robust slave-node implementation in automotive and industrial networks without external LIN transceivers - the MSP430F2132IPW handles frame synchronization, checksum calculation, and wake-up pattern detection in firmware-assisted hardware mode.
How many I/O pins does the MSP430F2132IPW provide, and what are their capabilities?
The MSP430F2132IPW provides 24 individually configurable I/O pins across Ports P1 (8 pins), P2 (8 pins), and P3 (8 pins). Each pin supports digital input/output, programmable pullup/pulldown resistors, and edge-selectable interrupts. Ports P1 and P2 additionally support interrupt-on-change functionality for all bits, enabling efficient wake-up from low-power modes on external events such as button presses or sensor triggers.
What development tools are compatible with the MSP430F2132IPW?
The MSP430F2132IPW is supported by TI's MSP-FET430UIF (USB JTAG), MSP-FET430U28 (TSSOP-28 target board), and MSP-GANG430 production programmer. Its integrated Embedded Emulation Module (EEM) enables full-speed debugging, flash programming, and real-time variable inspection. The device also supports UART-based firmware updates via its Bootstrap Loader (BSL) using standard serial interfaces - no JTAG hardware required for field upgrades.
Is the MSP430F2132IPW pin-compatible with other devices in the MSP430F21x2 family?
Yes, the MSP430F2132IPW shares identical pinout and electrical characteristics with MSP430F2112IPW and MSP430F2122IPW in the TSSOP-28 (PW) package. All three devices use the same 28-pin mapping, I/O structure, peripheral register layout, and power domains - enabling direct PCB-level substitution where Flash/RAM requirements align, without layout or firmware changes.
