Product details

Overview

MSP430F5132IDA from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller in a 38-pin TSSOP package, 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), 10-bit 200-ksps ADC with 8 external + 2 internal channels, and 16-channel comparator. It targets battery-powered sensor systems and digital power supplies requiring sub-µA standby current.

For engineers reviewing the MSP430F5132IDA datasheet, MSP430F5132IDA pinout, MSP430F5132IDA application, or MSP430F5132IDA equivalent, key selection criteria include its 1.8–3.6 V supply range, 1.1 µA LPM3 standby current, 5-V-tolerant I/Os with 20-mA drive, integrated LDO core regulation, and support for crystal oscillators up to 25 MHz - all validated for use in thermostats, remote controls, and LED lighting subsystems.

Technical Context

The MSP430F5132IDA implements a unified clock system with FLL-based frequency stabilization, low-power VLO and trimmed REFO internal sources, plus XT1 support for 32-kHz and up to 25-MHz crystals. Its CPUXV2 core executes instructions in 40 ns, aided by constant generators and a 32-bit hardware multiplier for efficient signal processing.

Power management includes programmable LDO output voltage, supply voltage supervision (SVM/SVS), brownout reset, and five low-power modes - enabling wake-up from LPM3 in under 5 µs. Peripheral integration centers on two high-resolution Timer_D modules (each with three capture/compare registers and buffer/event control), DMA-driven data movement, and flexible port mapping for pin reuse across UART, I²C, SPI, ADC, and comparator functions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MSP430F5152IDA	16 KB Flash / 2 KB RAM; identical peripherals and pinout - no hardware changes required.	Supports larger firmware images (e.g., BLE stack + sensor fusion) where MSP430F5132IDA's 8 KB Flash is insufficient.	Select when future firmware expansion or additional protocol stacks are anticipated without altering PCB layout.
MSP430F5131IDA	No ADC10_A module; lacks 10-bit ADC, internal reference, and temperature sensor - ADC-related pins repurposed as GPIO.	Suitable only for purely digital control applications (e.g., simple LED sequencers) where analog sensing is unnecessary.	Choose only if ADC functionality is excluded from design - not a drop-in replacement for MSP430F5132IDA in sensor-based systems.

Compared with MSP430F5152IDA, the MSP430F5132IDA offers lower memory cost and smaller code footprint for basic sensor readout and communication; versus MSP430F5131IDA, it adds essential analog capability at minimal silicon area premium - making it optimal for cost-sensitive, mixed-signal edge nodes.

The MSP430F5132IDA supports high-frequency crystals up to 25 MHz on the XT1 oscillator input. This enables precise clocking for high-speed UART communication (e.g., 115.2 kbps with zero error), accurate PWM generation, and deterministic real-time execution - all verified in the SLAS619R datasheet Section 5.22.

Does the MSP430F5132IDA include an integrated ADC, and what are its key specifications?

Yes, the MSP430F5132IDA integrates a 10-bit ADC (ADC10_A) with 200-ksps sampling rate, internal reference, sample-and-hold, autoscan, and support for up to 8 external and 2 internal channels (including on-die temperature sensor). These capabilities are confirmed in the device overview and Section 5.38–5.42 of the SLAS619R datasheet.

How many I/O pins on the MSP430F5132IDA are 5-V tolerant, and what is their drive strength?

The MSP430F5132IDA provides up to twelve 5-V-tolerant digital I/O pins with configurable 20-mA drive strength. This is explicitly stated in the "Features" section of the SLAS619R datasheet and applies to the 38-pin DA package variant - enabling direct interfacing with 5-V logic without external level shifters.

The MSP430F5132IDA supports five low-power modes, including LPM3 (1.1 µA at 3 V), LPM4 (0.9 µA RAM retention), and LPM4.5 (0.25 µA shutdown). Active mode current is 180 µA/MHz - measured under typical conditions per Section 5.4 of SLAS619R - making it suitable for intermittent sensing with rapid wake-up.

Is the MSP430F5132IDA pin-compatible with other devices in the MSP430F51x2 family?

Yes, the MSP430F5132IDA shares identical pinout and package (38-pin TSSOP) with MSP430F5152IDA and MSP430F5172IDA. All three support the same peripheral mappings and electrical characteristics - allowing hardware reuse across memory variants without PCB redesign, as confirmed in Table 3-1 and Figure 4-2 of SLAS619R.
