Product details
Overview
MSP430F5132IDAR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 8 KB Flash, 1 KB RAM, dual 16-bit Timer_D modules (TD0/TD1), USCI_A0 (UART/IrDA/SPI) and USCI_B0 (I²C/SPI), a 10-bit 200-ksps ADC with 8 external + 2 internal channels (including temperature sensor), 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 MSP430F5132IDAR datasheet, MSP430F5132IDAR pinout, MSP430F5132IDAR application, or MSP430F5132IDAR equivalent, key selection criteria include its 40-pin TSSOP (DA) 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 constrained industrial and metering designs.
Technical Context
The MSP430F5132IDAR implements the MSP430F51x2 family architecture with CPUXV2 core, 3-channel DMA, and unified clock system including FLL, VLO, REFO, XT1 (32 kHz to 25 MHz), and DCO. Its Timer_D modules support high-resolution mode up to 256 MHz and event-controlled buffering, enabling precise PWM generation and time-critical capture/compare operations.
Peripherals are managed via a port mapping controller allowing dynamic reassignment of secondary functions (e.g., USCI, ADC, Timer) across I/O pins. The device supports serial onboard programming without external voltage and includes supply supervision (SVM/SVS), brownout reset, and CRC16 hardware acceleration - all optimized for robust operation in analog-digital mixed-signal environments.

FAQ
What is the maximum operating frequency of the MSP430F5132IDAR?
The MSP430F5132IDAR supports a maximum system clock (MCLK) frequency of 25 MHz using the high-frequency crystal oscillator (XT1). Its DCO can be tuned to match this frequency, and the FLL stabilizes it with low jitter - enabling deterministic real-time response for time-critical control loops in the MSP430F5132IDAR.
Does the MSP430F5132IDAR support in-system programming without external voltage?
Yes, the MSP430F5132IDAR supports serial onboard programming (SBP) via Spy-Bi-Wire using only the RST/NMI/SBWTDIO and TEST/SBWTCK pins. No external programming voltage is required - the MSP430F5132IDAR draws power from the target system's DVCC rail during programming, simplifying production and field updates.
How many I/O pins on the MSP430F5132IDAR are 5-V tolerant?
Twelve I/O pins on the MSP430F5132IDAR are 5-V tolerant: P1.0–P1.5, P3.2–P3.7, and PJ.0–PJ.6. These pins operate safely with 5-V signals while powered from 1.8–3.6 V, eliminating external level shifters when interfacing with legacy 5-V peripherals - a key design advantage of the MSP430F5132IDAR.
What ADC channels are available on the MSP430F5132IDAR?
The MSP430F5132IDAR includes a 10-bit ADC10_A module with eight external input channels (A0–A5, A7, A8) and two internal channels (temperature sensor and VREF generator). This configuration supports simultaneous multi-sensor acquisition in compact systems - a defining capability of the MSP430F5132IDAR for analog-digital hybrid applications.
Is the MSP430F5132IDAR pin-compatible with other devices in the MSP430F51x2 family?
Yes, the MSP430F5132IDAR in the 38-pin TSSOP (DA) package shares identical pinout and signal mapping with MSP430F5152IDAR and MSP430F5172IDAR. This allows drop-in replacement for memory upgrades or feature scaling - provided software accounts for differences in Flash/RAM size and ADC presence - making the MSP430F5132IDAR part of a scalable migration path.
