Overview
MSP430F2132TRTVR 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 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 MSP430F2132TRTVR datasheet, MSP430F2132TRTVR pinout, MSP430F2132TRTVR application, or MSP430F2132TRTVR equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options for low-power embedded design.
Technical Context
The MSP430F2132TRTVR implements a 16-bit CPU with seven addressing modes and 16 general-purpose registers, enabling single-cycle register-to-register execution. Its basic clock module integrates a digitally controlled oscillator (DCO) calibrated to ±1% at four frequencies up to 16 MHz, plus support for 32-kHz crystal, HF crystal (≤16 MHz), resonator, or external digital clock.
Peripherals are memory-mapped and fully accessible via all CPU instructions. The device supports five low-power modes (LPM0–LPM4), with wake-up from standby in <1 µs, and includes on-chip emulation (Spy-Bi-Wire), bootstrap loader (BSL), and programmable code protection via security fuse.
Key Specifications

FAQ
What is the maximum operating frequency of the MSP430F2132TRTVR?
The MSP430F2132TRTVR supports a maximum system clock frequency of 16 MHz, achievable using the internal digitally controlled oscillator (DCO) calibrated to ±1% or an external high-frequency crystal up to 16 MHz. This frequency is used for MCLK and enables full-speed execution of the 16-bit RISC core and peripheral modules like the 200-ksps ADC.
Does the MSP430F2132TRTVR support in-system programming without external hardware?
Yes, the MSP430F2132TRTVR supports in-system programming via its built-in bootstrap loader (BSL), which uses UART (P1.1/P2.2) for firmware updates. It also supports Spy-Bi-Wire programming through RST/NMI/SBWTDIO and TEST/SBWTCK pins, eliminating the need for external JTAG emulators during development and field updates.
How many analog input channels does the integrated ADC support on the MSP430F2132TRTVR?
The MSP430F2132TRTVR's 10-bit ADC10 module supports eight analog input channels (A0–A7), mapped to P1.0, P2.0–P2.4, P3.0, P3.6, and P3.7. Channel selection is software-controlled, and autoscan mode allows sequential conversion of multiple channels without CPU intervention, leveraging the integrated data transfer controller (DTC).
What low-power modes are available on the MSP430F2132TRTVR, and what is the lowest current draw?
The MSP430F2132TRTVR offers six operating modes: Active mode and five low-power modes (LPM0–LPM4). In LPM4 (RAM retention only), it draws just 0.1 µA at 2.2 V, with all clocks and the DCO disabled. Wake-up from LPM4 occurs in less than 1 µs via interrupt, making it ideal for infrequent-event sensing applications.
Is the MSP430F2132TRTVR pin-compatible with other devices in the MSP430F21x2 family?
Yes, the MSP430F2132TRTVR in the 32-pin RTV package shares identical pinout and electrical characteristics with MSP430F2112IRTV and MSP430F2122IRTV. This allows direct substitution within the same package variant, provided firmware accommodates differences in flash size (2 KB/4 KB/8 KB) and peripheral enablement.
