Product details
Overview
MSP430F2132TRHBR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 8 KB flash, 512 B 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 GPIO pins. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430F2132TRHBR datasheet, MSP430F2132TRHBR pinout, MSP430F2132TRHBR application, or MSP430F2132TRHBR equivalent, key selection criteria include its sub-1 µs wake-up time from 0.1 µA off-mode, calibrated DCO supporting 1–16 MHz operation without external crystal, integrated comparator for slope A/D, and QFN-32 package suitability for space-constrained designs.
Technical Context
The MSP430F2132TRHBR implements a 16-bit CPU with seven addressing modes and constant generators for high code efficiency. Its basic clock module integrates a digitally controlled oscillator (DCO), low-frequency internal oscillator, and support for 32-kHz crystal or HF crystal up to 16 MHz - all enabling flexible low-power clocking across five LPMs.
Peripherals are memory-mapped and accessible via full instruction set; the ADC10 includes autoscan, sample-and-hold, and data transfer controller (DTC) for autonomous conversion sequences, while USCI modules provide hardware-configurable UART, LIN, IrDA, SPI, and I²C protocols without CPU overhead.

FAQ
What is the maximum operating frequency of the MSP430F2132TRHBR?
The MSP430F2132TRHBR supports up to 16 MHz operation via its factory-calibrated digitally controlled oscillator (DCO), with four trim points (1/8/12/16 MHz) accurate to ±1% across voltage and temperature. External crystals up to 16 MHz are also supported on XIN/XOUT pins, and the DCO can be locked to crystal reference for higher stability.
Does the MSP430F2132TRHBR support in-system programming without external hardware?
Yes, the MSP430F2132TRHBR includes a built-in bootstrap loader (BSL) that enables flash programming via UART using only the P1.1 (RX) and P2.2 (TX) pins. No external programmer is required - firmware updates can be performed in the field using standard serial commands and user-defined password protection.
How many analog input channels does the ADC10 module support on the MSP430F2132TRHBR?
The ADC10 module on the MSP430F2132TRHBR supports eight analog input channels (A0–A7), mapped to P2.0, P2.1, P2.2, P2.3, P2.4, P3.0, P3.6, and P3.7. It includes internal 1.5 V/2.5 V references, sample-and-hold, autoscan mode, and a data transfer controller (DTC) for autonomous result storage without CPU involvement.
What debug interface does the MSP430F2132TRHBR use, and what pins are required?
The MSP430F2132TRHBR uses Spy-Bi-Wire (2-wire JTAG) for debugging and programming, requiring only two pins: RST/NMI/SBWTDIO (Pin 5) and TEST/SBWTCK (Pin 29). This minimal interface enables full-speed emulation, flash programming, and real-time variable inspection using TI's MSP-FET430UIF or compatible tools.
Is the MSP430F2132TRHBR qualified for industrial temperature range operation?
Yes, the MSP430F2132TRHBR is specified for operation from –40°C to +105°C (industrial grade), as confirmed by TI's ordering option table where "T" suffix denotes extended temperature range. Its brownout detector, calibrated DCO, and tested flash endurance ensure reliable functionality across this full range.
