Product details
Overview
MSP430F5131IYFFT 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), 3-channel DMA, and 16-channel comparator. It operates from 1.8 V to 3.6 V and supports wake-up from LPM3 in <5 µs - ideal for battery-powered sensor nodes and digital thermostats.
For engineers reviewing the MSP430F5131IYFFT datasheet, MSP430F5131IYFFT pinout, MSP430F5131IYFFT application, or MSP430F5131IYFFT equivalent, key selection criteria include its 40-pin DSBGA (YFF) package, absence of integrated ADC (unlike F51x2 variants), 5-V-tolerant I/Os with up to 20-mA drive, and compatibility with TI's MSP430F51x1 family toolchain and firmware libraries.
Technical Context
The MSP430F5131IYFFT implements the CPUXV2 core with constant generators and a 40-ns instruction cycle. Its unified clock system integrates FLL stabilization, VLO (10 kHz), REFO (32.768 kHz), and support for external crystals up to 25 MHz on XT1. Power management includes an on-chip LDO with programmable core voltage and brownout detection.
Peripheral architecture centers on reconfigurable port mapping (PMM), enabling dynamic assignment of USCI, Timer_D, and comparator functions to GPIO pins. The device lacks ADC10_A (confirmed in Device Comparison Table 3-1 and Signal Descriptions footnote 3), distinguishing it from MSP430F51x2 members and targeting applications where analog conversion is handled externally or omitted.

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 |
|---|---|---|---|
| MSP430F5151IYFFT | 16 KB Flash, 2 KB RAM; identical peripherals, package, and power specs | Supports larger firmware images and more complex state machines; same pinout and code compatibility | Select when firmware exceeds 8 KB or requires extended RAM for buffering or encryption routines |
| MSP430F5132IRSBT | Same Flash/RAM as MSP430F5131 but adds 10-bit ADC10_A with 8 external + 2 internal channels | Enables direct analog sensing (e.g., thermistor, light sensor) without external ADC; uses 40-pin QFN instead of DSBGA | Choose only if on-chip ADC is required and QFN assembly is acceptable; not drop-in compatible due to package and ADC presence |
Compared with MSP430F5131IYFFT, the MSP430F5151IYFFT offers scalable memory while maintaining identical low-power behavior and pin compatibility, whereas the MSP430F5132IRSBT trades package form factor and adds ADC functionality - making it suitable for cost-sensitive analog-sensing designs where DSBGA is not mandated.

FAQ
Does MSP430F5131IYFFT include an integrated analog-to-digital converter (ADC)?
No, the MSP430F5131IYFFT does not include an ADC. It belongs to the MSP430F51x1 family, which omits the ADC10_A module present in MSP430F51x2 variants (e.g., MSP430F5132). This is confirmed in Table 3-1 (Device Comparison) and Signal Descriptions footnote 3. Applications requiring analog sensing must use external ADCs or select an F51x2 part.
What is the maximum operating frequency supported by MSP430F5131IYFFT?
The MSP430F5131IYFFT supports up to 25 MHz via the XT1 high-frequency crystal oscillator mode. Its CPUXV2 core achieves a 40-ns instruction cycle time, enabling deterministic execution at 25 MHz. Internal DCO and FLL allow stable frequency synthesis without external high-speed crystals when lower precision is acceptable.
Is MSP430F5131IYFFT pin-compatible with other packages in the MSP430F51x1 family?
No - the MSP430F5131IYFFT uses a 40-ball DSBGA (YFF) package, while other variants like MSP430F5131IDA use 38-pin TSSOP and MSP430F5131IRSBR use 40-pin QFN. Pin functions differ across packages due to ball/pad layout and signal availability (e.g., some I/Os are absent in TSSOP). Always consult the specific package's Signal Descriptions table.
Can MSP430F5131IYFFT operate from a single 3.3-V supply?
Yes, the MSP430F5131IYFFT operates across 1.8 V to 3.6 V. At 3.3 V, it delivers full performance: 25-MHz XT1 support, 20-mA I/O drive, and all low-power modes function as specified. The internal LDO regulates VCORE to 1.8–2.2 V regardless of DVCC, ensuring stable core operation across the supply range.
What debug interface does MSP430F5131IYFFT support?
The MSP430F5131IYFFT supports Spy-Bi-Wire (SBW), a 2-wire JTAG variant using RST/NMI/SBWTDIO and TEST/SBWTCK pins. It is fully compatible with TI's MSP-FET and IAR Embedded Workbench. No external debug header is needed - SBW connects directly via standard 2-pin cabling for programming and real-time debugging.
