Product details
Overview
MSP430F5131IYFFR 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), 16-channel comparator, and 5-V-tolerant I/Os in a 40-pin DSBGA package. It operates from 1.8 V to 3.6 V and supports sub-µA standby (1.1 µA LPM3) and shutdown (0.25 µA LPM4.5) modes for battery-powered sensor and control systems.
For engineers reviewing the MSP430F5131IYFFR datasheet, MSP430F5131IYFFR pinout, MSP430F5131IYFFR application, or MSP430F5131IYFFR equivalent, this page delivers verified technical context, exact pin functions per YFF package, real-world use cases in digital power supplies and thermostats, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The MSP430F5131IYFFR implements the MSP430F51x1 family architecture-lacking the ADC10_A module present in F51x2 variants-making it functionally distinct from MSP430F5132. Its unified clock system integrates FLL stabilization, VLO (10 kHz), REFO (32.768 kHz), and support for external crystals up to 25 MHz via XT1.
Power management includes a programmable LDO core regulator, supply voltage supervision (SVM/SVS), brownout reset, and five low-power modes. Peripheral control uses a port mapping controller enabling dynamic reassignment of secondary functions-including TD0/TD1 capture/compare, USCI signals, and comparator inputs-across 29 GPIO pins.

FAQ
What is the maximum operating frequency of the MSP430F5131IYFFR?
The MSP430F5131IYFFR supports a maximum system clock (MCLK) frequency of 25 MHz when driven by an external crystal via XT1. Its digitally controlled oscillator (DCO) is calibrated to achieve stable operation across voltage and temperature, enabling deterministic real-time execution without external clock components in many applications.
Does the MSP430F5131IYFFR include an analog-to-digital converter (ADC)?
No, the MSP430F5131IYFFR does not include the ADC10_A module. It belongs to the MSP430F51x1 family, which omits the 10-bit ADC present in the F51x2 variants (e.g., MSP430F5132IYFFR). This omission reduces power consumption and cost where analog sensing is handled externally or is unnecessary.
What package type is used for the MSP430F5131IYFFR?
The MSP430F5131IYFFR uses a 40-pin die-sized ball grid array (DSBGA) package designated YFF. It measures 2.4 mm × 2.4 mm with 0.4-mm ball pitch, providing high I/O density and excellent thermal performance for space-constrained applications like wearables and smart sensors.
Can the MSP430F5131IYFFR operate from a single 3.3-V supply?
Yes, the MSP430F5131IYFFR operates across a supply range of 1.8 V to 3.6 V. At 3.3 V, it delivers full performance-including 25-MHz MCLK operation, 20-mA I/O drive, and all low-power modes-with typical active current of 180 µA/MHz and LPM3 current of 1.1 µA.
How is programming and debugging performed on the MSP430F5131IYFFR?
Programming and debugging of the MSP430F5131IYFFR is performed via the Spy-Bi-Wire (SBW) interface using the RST/NMI/SBWTDIO and TEST/SBWTCK pins. This 2-wire protocol supports full-speed emulation, flash programming, and real-time register inspection using TI's MSP-FET or compatible debuggers-no external voltage required.
