Texas Instruments MSP430F2132IRTVR

Overview

MSP430F2132IRTVR 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 comparator_A+ for slope A/D or battery monitoring - deployed in portable sensor nodes and battery-powered metering systems.

For engineers reviewing the MSP430F2132IRTVR datasheet, MSP430F2132IRTVR pinout, MSP430F2132IRTVR application, or MSP430F2132IRTVR equivalent, key selection criteria include active-mode current at 1 MHz (250 µA), standby current (0.7 µA), 32-pin QFN (RTV) package footprint, LIN-capable UART with auto-baudrate detection, and integrated DCO calibrated to ±1% across temperature.

Technical Context

The MSP430F2132IRTVR implements a 16-bit RISC CPU with seven addressing modes and constant generators for high code efficiency. Its clock system integrates a digitally controlled oscillator (DCO) with four factory-calibrated frequencies up to 16 MHz, plus support for external HF crystal (≤16 MHz), 32-kHz watch crystal, or resistor-based tuning via P2.5/ROSC.

Peripherals are memory-mapped and accessible via all CPU instructions. The USCI modules provide protocol-flexible serial communication: USCI_A0 supports UART with LIN auto-baudrate detection and IrDA encoding/decoding; USCI_B0 supports SPI and I²C master/slave operation. The ADC10 includes sample-and-hold, autoscan, and data transfer controller (DTC) for autonomous conversion sequences without CPU intervention.

FAQ

What is the maximum operating frequency of the MSP430F2132IRTVR?

The MSP430F2132IRTVR supports a maximum system clock (MCLK) frequency of 16 MHz, achieved either via its internal digitally controlled oscillator (DCO) - calibrated to ±1% at four frequencies including 16 MHz - or through an external high-frequency crystal up to 16 MHz connected to XIN/XOUT pins. This enables deterministic real-time execution in time-critical sensor processing tasks.

Does the MSP430F2132IRTVR support LIN bus communication?

Yes, the MSP430F2132IRTVR supports LIN 2.x communication through its USCI_A0 module, which implements enhanced UART with automatic baudrate detection (LIN autobaud). This allows direct connection to a LIN transceiver without external protocol translation, making it suitable for automotive body electronics and industrial sub-networks.

How much SRAM and Flash memory does the MSP430F2132IRTVR include?

The MSP430F2132IRTVR integrates 512 bytes of RAM and 8KB of Flash memory (plus 256B of information memory for calibration data and BSL). This memory configuration supports moderate firmware complexity, real-time data buffering, and field-upgradable code storage - sufficient for most compact sensor node and metering applications.

What low-power modes are available on the MSP430F2132IRTVR?

The MSP430F2132IRTVR provides six operating modes: Active Mode (AM) and five low-power modes (LPM0–LPM4). LPM4 achieves 0.1 µA current with RAM retention, while LPM3 draws 0.2 µA with ACLK active - enabling multi-year battery life in intermittently active sensing applications such as water meters or environmental monitors.

Is the MSP430F2132IRTVR pin-compatible with other MSP430F21x2 variants?

Yes, the MSP430F2132IRTVR shares identical pinout and package (32-pin QFN RTV) with other F21x2 family members including MSP430F2112IRTVR and MSP430F2122IRTVR. This allows hardware reuse across different Flash/RAM configurations - for example, prototyping with MSP430F2132IRTVR and scaling down to MSP430F2122IRTVR in volume production without PCB changes.
