Product details
Overview
MSP430F5132IRSBT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 8 KB Flash, 1 KB RAM, dual 16-bit Timer_D modules (TD0/TD1), USCI_A0 (UART/IrDA/SPI) and USCI_B0 (I²C/SPI), 10-bit 200-ksps ADC with 8 external + 2 internal channels, and 16-channel comparator. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and digital power supplies.
For engineers reviewing the MSP430F5132IRSBT datasheet, MSP430F5132IRSBT pinout, MSP430F5132IRSBT application, or MSP430F5132IRSBT equivalent, key selection criteria include its 40-pin QFN (RSB) package, 5-V-tolerant I/Os with 20-mA drive strength, sub-5-µs wake-up from LPM3, and integrated LDO with programmable core voltage - all critical for low-power embedded control in space-constrained designs.
Technical Context
The MSP430F5132IRSBT implements a unified clock system with FLL-based frequency stabilization, dual independent 16-bit Timer_D modules supporting high-resolution mode and event-controlled buffering, and a hardware 32-bit multiplier enabling efficient signal processing. Its port mapping controller allows dynamic reassignment of peripheral functions across multiple pins.
It integrates a flexible power-management system featuring supply-voltage supervision, brownout reset, and four low-power modes (LPM0–LPM4.5), with LPM4.5 consuming only 0.25 µA at 3 V. The ADC supports autoscan and internal reference, while the comparator includes ultra-low-power operation and dedicated output routing via CBOUT.

This 2-wire interface enables full-speed debugging, flash programming, and real-time register inspection without requiring a full 4-wire JTAG connector, preserving PCB space and simplifying development for the MSP430F5132IRSBT.
Can the MSP430F5132IRSBT operate from a single 3.3-V supply?
Yes, the MSP430F5132IRSBT operates across 1.8 V to 3.6 V, making 3.3 V a fully supported and commonly used supply voltage. At 3.3 V, it delivers 180 µA/MHz active current and maintains full functionality of its 5-V-tolerant I/Os, ADC, timers, and USCI peripherals - ideal for integration into standard 3.3-V embedded systems using the MSP430F5132IRSBT.
How many ADC input channels does the MSP430F5132IRSBT support?
The MSP430F5132IRSBT supports 8 external analog input channels (A0–A7) plus 2 internal channels (including the on-die temperature sensor), for a total of 10 selectable inputs to its 10-bit, 200-ksps ADC10_A module. Channel selection is software-configurable, and autoscan mode enables automatic sequential conversion - a key capability confirmed for the MSP430F5132IRSBT in the device comparison table.
Is the MSP430F5132IRSBT pin-compatible with other devices in the MSP430F51x2 family?
Yes, the MSP430F5132IRSBT in the 40-pin RSB package shares identical pinout and signal mapping with MSP430F5152IRSBT and MSP430F5172IRSBT. All three devices support the same peripheral assignments on each pin, enabling drop-in replacement based on memory or ADC requirements - a documented feature confirmed in TI's SLAS619R datasheet for the MSP430F5132IRSBT.
