Product details
Overview
MSP430F2132TRTVT 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 targets battery-powered sensor nodes and portable instrumentation requiring sub-1-µs wake-up and <0.1 µA off-mode retention.
For engineers reviewing the MSP430F2132TRTVT datasheet, MSP430F2132TRTVT pinout, MSP430F2132TRTVT application, or MSP430F2132TRTVT equivalent, key selection criteria include its 32-pin QFN (RTV) package, -40°C to 105°C industrial temperature grade, integrated comparator for slope A/D, and calibrated DCO enabling 1–16 MHz operation without external crystal.
Technical Context
The MSP430F2132TRTVT 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) calibrated at four frequencies (±1%), a 32-kHz LF oscillator, and support for HF crystals up to 16 MHz - enabling sub-1-µs wake-up from LPM4.
Peripherals are memory-mapped and accessible via all instructions. The ADC10 includes sample-and-hold, autoscan, and a dedicated Data Transfer Controller (DTC) that moves conversion results to RAM without CPU intervention. The comparator_A+ supports analog signal monitoring and battery voltage supervision.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2132IPW | Same core, memory, and peripherals; packaged in 28-pin TSSOP (PW) instead of 32-pin QFN (RTV); rated for -40°C to 85°C only | Suitable for commercial-temperature PCBs with larger pitch requirements; lacks extended temperature range and thermal pad for high-reliability industrial use | Select when board layout favors TSSOP, ambient temperature stays below 85°C, and thermal dissipation is less critical |
| MSP430F2330IRTVT | Pin-compatible RTV package; adds 16 KB Flash, 1 KB RAM, hardware multiplier, DMA, and enhanced USCI (dual UART/I²C); operates at same voltage/temp range | Required for applications needing larger firmware, real-time FFT processing, or simultaneous multi-protocol communication (e.g., BLE coexistence + RS-485) | Choose when future firmware expansion, higher computational load, or additional peripheral bandwidth is anticipated - no PCB change needed |
Compared with MSP430F2132TRTVT, the IPW variant trades thermal performance and temperature range for through-hole compatibility, while the F2330IRTVT delivers scalable compute and memory headroom within identical packaging - making it a direct upgrade path for evolving system requirements.

FAQ
What is the maximum operating frequency of the MSP430F2132TRTVT?
The MSP430F2132TRTVT supports up to 16 MHz operation using its factory-calibrated digitally controlled oscillator (DCO). This frequency is achievable without external crystal components, as four DCO calibration points (1/8/12/16 MHz) are stored in information memory segment A with ±1% accuracy at 2.2 V and 30°C.
Does the MSP430F2132TRTVT support hardware UART with automatic baud rate detection?
Yes, the MSP430F2132TRTVT's USCI_A0 module supports enhanced UART with LIN-compliant auto-baudrate detection. This feature allows the MSP430F2132TRTVT to automatically synchronize to incoming serial frames without prior knowledge of the transmitter's bit rate - essential for robust automotive and industrial bus interoperability.
How many analog input channels does the ADC10 in the MSP430F2132TRTVT support?
The ADC10 in the MSP430F2132TRTVT supports eight analog input channels (A0–A7), mapped across P1.0, P2.0–P2.4, and P3.0, P3.6–P3.7. These inputs can be scanned automatically in sequence using the ADC10's autoscan mode, and conversion results are transferred to memory via the integrated Data Transfer Controller (DTC) without CPU involvement.
What debug interface does the MSP430F2132TRTVT use, and how many pins are required?
The MSP430F2132TRTVT uses the Spy-Bi-Wire (SBW) interface for programming and debugging, requiring only two pins: TEST/SBWTCK (Pin 29) and RST/NMI/SBWTDIO (Pin 5). This two-wire JTAG subset enables full-speed emulation and flash programming while minimizing PCB routing complexity and connector footprint.
Is the MSP430F2132TRTVT pin-compatible with other devices in the MSP430F21x2 family?
Yes, the MSP430F2132TRTVT shares identical pinout and electrical characteristics with other 32-pin QFN (RTV) variants in the MSP430F21x2 family, including MSP430F2122IRTV and MSP430F2112IRTV. Firmware and hardware designs can be reused across these parts by adjusting Flash/RAM allocation and peripheral initialization - simplifying migration between memory configurations.
