Product details
Overview
MSP430F5151IYFFR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller in a 40-pin DSBGA (YFF) package, featuring 16 KB Flash, 2 KB RAM, dual 16-bit Timer_D modules, USCI_A0/USCI_B0 interfaces (UART/IrDA/SPI/I²C), 16-channel comparator, and 5-V-tolerant I/Os. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and digital power control.
For engineers reviewing the MSP430F5151IYFFR datasheet, MSP430F5151IYFFR pinout, MSP430F5151IYFFR application, or MSP430F5151IYFFR equivalent, this page delivers verified technical context, exact pin functions per YFF package, real-world use cases in LED lighting and thermostats, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The MSP430F5151IYFFR implements the MSP430F51x1 family architecture-lacking the ADC10_A module present in F51x2 variants-so it supports no analog-to-digital conversion. Its unified clock system integrates FLL stabilization, VLO (10 kHz), REFO (32.768 kHz), and XT1 support for 32-kHz crystals or up to 25-MHz high-frequency crystals.
Power management includes an integrated LDO with programmable core voltage, supply supervision (SVS/SVM), brownout reset, and five low-power modes (LPM0–LPM4.5). Wake-up from LPM3 occurs in under 5 µs, and active-mode current is 180 µA/MHz at 3 V.
Key Specifications

FAQ
Does MSP430F5151IYFFR include an analog-to-digital converter (ADC)?
No, the MSP430F5151IYFFR belongs to the MSP430F51x1 family and does not integrate the ADC10_A module. This is confirmed in the device comparison table and functional block diagrams-only MSP430F51x2 variants (e.g., MSP430F5152IYFFR) include the 10-bit ADC. External ADCs must be used if analog sensing is required with the MSP430F5151IYFFR.
What is the package type and ball pitch of MSP430F5151IYFFR?
The MSP430F5151IYFFR uses a 40-ball DSBGA package (YFF suffix), measuring 2.1 mm × 2.1 mm with 0.4-mm ball pitch. This is explicitly listed in TI's Package Option Addendum and confirmed in the mechanical drawings of SLAS619R. The YFF package supports fine-pitch PCB assembly and thermal performance suitable for compact industrial modules.
Can MSP430F5151IYFFR operate from a 3.3-V supply?
Yes, the MSP430F5151IYFFR supports 1.8 V to 3.6 V operation per its recommended operating conditions. At 3.3 V, it delivers full performance-including 180 µA/MHz active current, 1.1 µA LPM3, and full 5-V-tolerant I/O drive-making it compatible with standard 3.3-V system rails without regulators or level shifters.
Is MSP430F5151IYFFR pin-compatible with MSP430F5152IYFFR?
Yes, the MSP430F5151IYFFR and MSP430F5152IYFFR share identical 40-ball YFF packaging, pin assignment, and signal definitions-including all I/O, power, clock, and debug terminals. The only functional difference is the presence of ADC10_A in the F5152 variant; all other peripherals, memory maps, and register layouts are identical.
What debug interface does MSP430F5151IYFFR support?
The MSP430F5151IYFFR supports Spy-Bi-Wire (SBW) debugging via the RST/NMI/SBWTDIO and TEST/SBWTCK pins-requiring only two connections for full in-system programming and real-time debugging. JTAG is not supported on this device; SBW is the standard, space-efficient interface for all MSP430F5xx YFF-packaged devices.
