Product details
Overview
MSP430F5151IYFFT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 16 KB Flash, 2 KB RAM, dual 16-bit Timer_D modules (TD0/TD1), USCI_A0 (UART/IrDA/SPI) and USCI_B0 (I²C/SPI), 5-V-tolerant I/Os, and a 16-channel comparator. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and digital power control.
For engineers reviewing the MSP430F5151IYFFT datasheet, MSP430F5151IYFFT pinout, MSP430F5151IYFFT application, or MSP430F5151IYFFT equivalent, key selection criteria include LPM3 standby current (1.1 µA @ 3 V), 40-pin DSBGA package compatibility, absence of integrated ADC (unlike F51x2 variants), and pin-mapped Timer_D/USCI peripheral availability in YFF layout.
Technical Context
The MSP430F5151IYFFT belongs to the MSP430F51x1 subfamily - distinguished from F51x2 by omission of the 10-bit ADC10_A module and external analog input channels. It retains full Timer_D (TD0/TD1 with three capture/compare registers each), USCI_A0/USCI_B0, hardware multiplier, and 3-channel DMA.
Its unified clock system includes FLL stabilization, VLO (10 kHz), REFO (32.768 kHz), XT1 support for 32-kHz crystals or up to 25-MHz high-frequency crystals, and programmable LDO core regulation. Power management enables wake-up from LPM3 in <5 µs with brownout detection and SVS/SVM supervision.
Key Specifications

Pinout & Package
Package: 40-ball DSBGA (YFF), 2.4 mm × 2.4 mm, 0.4-mm pitch, bottom-side solder balls. Pinout conforms to TI's standardized YFF mapping for MSP430F51x1 devices, with DVIO, DVCC, DVSS, AVSS, VCORE, XIN/XOUT, RST/NMI/SBWTDIO, TEST/SBWTCK, and fully mapped port pins P1–P3, PJ.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0–P1.5 | Multi-function I/O with USCI_A0/USCI_B0 secondary roles | Configurable as UART TX/RX, SPI master/slave, or I²C SDA/SCL - enables flexible peripheral routing without PCB redesign |
| PJ.0–PJ.3 | Multi-function I/O with SMCLK/MCLK/ACLK/ADC10CLK outputs | Provides selectable clock outputs for synchronizing external logic or sensors; no external oscillator needed for basic timing |
| P2.0–P2.3, P3.0–P3.1 | Timer_D fault/clear inputs and CCR outputs | Supports hardware-based motor control safety monitoring and PWM dead-time insertion without CPU intervention |

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 |
|---|---|---|---|
| MSP430F5152IYFFT | Includes 10-bit ADC10_A with 8 external + 2 internal channels; otherwise identical Flash/RAM/peripherals | Required when analog sensing (e.g., thermistor, voltage divider) is performed on-chip without external ADC | Select F5152 if ADC integration reduces system cost/size; F5151 remains optimal when all analog signals are pre-conditioned externally |
| MSP430F5131IYFFT | 8 KB Flash, 1 KB RAM, same peripheral set; lower memory density but identical power/performance profile | Suitable for deeply embedded firmware with minimal feature set (e.g., fixed-function timer-only control) | Choose F5131 for cost-sensitive volume production where firmware fits in 8 KB and future updates are unlikely |
Compared with MSP430F5152IYFFT, the MSP430F5151IYFFT saves die area and cost by omitting the ADC while retaining full Timer_D, USCI, and low-power capabilities - making it ideal for digital-signal-dominant applications. Against MSP430F5131IYFFT, it doubles Flash/RAM for field-upgradable firmware and complex state machines.

FAQ
Does the MSP430F5151IYFFT include an integrated analog-to-digital converter (ADC)?
No, the MSP430F5151IYFFT does not include an integrated ADC. It belongs to the MSP430F51x1 family, which omits the ADC10_A module present in the F51x2 variants (e.g., MSP430F5152IYFFT). Analog signal acquisition must be handled externally or via discrete components interfaced through its 5-V-tolerant GPIOs and USCI peripherals.
What is the maximum operating frequency of the MSP430F5151IYFFT core?
While the MSP430F5151IYFFT's CPU executes instructions at 40 ns per cycle (25 MHz theoretical), its functional clock domains are constrained by the FLL and crystal sources. The device supports up to 25 MHz on XT1 for high-frequency crystal operation, and the DCO can be tuned to deliver stable MCLK/SMCLK frequencies appropriate for USCI baud rate generation and Timer_D timing - all within its 1.8–3.6 V supply range.
Which development tools are officially supported for programming the MSP430F5151IYFFT?
Texas Instruments officially supports the MSP430F5151IYFFT with the MSP-FET programmer/debugger and Code Composer Studio IDE. Its Spy-Bi-Wire (SBW) interface on RST/NMI/SBWTDIO and TEST/SBWTCK pins enables in-system programming and real-time debugging without a full JTAG header, reducing PCB footprint and test complexity during development and production.
How many I/O pins on the MSP430F5151IYFFT support 5-V tolerance, and what is their drive strength?
The MSP430F5151IYFFT provides up to twelve 5-V-tolerant digital I/O pins, with full drive strength rated at 20 mA per pin. These pins are distributed across ports P1 (P1.0–P1.5), P2 (P2.0–P2.7), and P3 (P3.2–P3.7), and require connection to the DVIO supply rail to enable 5-V tolerance - allowing direct interfacing with legacy 5-V logic and sensors.
Is the MSP430F5151IYFFT pin-compatible with other packages in the MSP430F51x1 family?
The MSP430F5151IYFFT uses the 40-ball DSBGA (YFF) package and is not pin-compatible with the 40-pin QFN (RSB) or 38-pin TSSOP (DA) variants of the same family. While electrical functionality and register mapping are identical, ball/pin assignments differ across packages - requiring separate PCB layouts. TI provides detailed mechanical drawings and signal mapping tables in Section 8 of the SLAS619R datasheet.
