Overview
MSP430F5132IYFFR 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 MSP430F5132IYFFR datasheet, MSP430F5132IYFFR pinout, MSP430F5132IYFFR application, or MSP430F5132IYFFR equivalent, this page delivers verified specifications, package-confirmed pin functions, real-world use cases, and validated alternative parts for low-power embedded design selection.
Technical Context
The MSP430F5132IYFFR implements a CPUXV2 core with constant generators and 40-ns instruction cycle time, paired with a unified clock system featuring FLL stabilization, VLO (12 kHz), REFO (32.768 kHz), and support for 32-kHz crystals (XT1) and up to 25-MHz high-frequency crystals. Its power architecture includes an integrated LDO with programmable core voltage and brownout detection.
Peripherals are managed via a Port Mapping Controller enabling dynamic I/O function reassignment. The device supports three DMA channels, hardware 32-bit multiplier, CRC16 engine, and ultra-low-power modes: LPM3 (1.1 µA @ 3 V), LPM4 (0.9 µA RAM retention), and LPM4.5 (0.25 µA shutdown).
Key Specifications

FAQ
What is the maximum operating frequency of the MSP430F5132IYFFR?
The MSP430F5132IYFFR supports up to 25 MHz via its XT1 high-frequency crystal oscillator. Its CPUXV2 core achieves a 40-ns instruction cycle time at this frequency, enabling real-time response in motor control and power conversion applications. The device also integrates a digitally controlled oscillator (DCO) that can be stabilized by the FLL for flexible clock generation without external crystals.
Does the MSP430F5132IYFFR support in-system programming without external voltage?
Yes, the MSP430F5132IYFFR supports serial onboard programming via Spy-Bi-Wire (SBW) using only the RST/NMI/SBWTDIO and TEST/SBWTCK pins-no external programming voltage is required. This capability is enabled by its integrated charge pump and bootstrapped programming circuitry, allowing field firmware updates through a 2-pin interface.
How many ADC input channels does the MSP430F5132IYFFR have, and what types are supported?
The MSP430F5132IYFFR includes a 10-bit ADC10_A module with 8 external analog input channels (A0–A5, plus two additional pins) and 2 internal channels (temperature sensor and VREF generator). It supports sample-and-hold, autoscan mode, and internal reference-enabling simultaneous multi-sensor acquisition without CPU polling.
Is the MSP430F5132IYFFR pin-compatible with other devices in the MSP430F51x2 family?
Yes, the MSP430F5132IYFFR in the 40-pin YFF package shares identical pinout and signal mapping with MSP430F5152IYFFR and MSP430F5172IYFFR. All three support the same peripheral functions on corresponding balls-including USCI_A0/B0, Timer_D, ADC, and comparator-enabling hardware reuse across performance tiers.
What low-power modes are available on the MSP430F5132IYFFR, and what are their typical currents?
The MSP430F5132IYFFR offers five low-power modes: LPM3 (1.1 µA @ 3 V, WDT active), LPM4 (0.9 µA @ 3 V, RAM retention), and LPM4.5 (0.25 µA @ 3 V, full shutdown). Active mode consumes 180 µA/MHz. These values are measured under specified conditions and enable multi-year operation in battery-powered thermostats and remote sensors.
