MSP430F5151IDAR

Microcontrollers Overview

The MSP430F5151IDAR is a mixed-signal microcontroller from the Texas Instruments MSP430F51x1 family. It features a 16-bit RISC CPU with a 40-ns instruction cycle time and operates within a supply voltage range of 1.8 V to 3.6 V. The device integrates 16 KB of Flash memory and 2 KB of RAM. Key peripherals include two 16-bit high-resolution timers (Timer_D), one Timer_A, two Universal Serial Communication Interfaces (USCI), a 3-channel DMA controller, and a 16-channel on-chip comparator. It lacks an integrated ADC but supports serial onboard programming without external voltage.

Microcontrollers Feature Summary

• Ultra-low power architecture optimized for extended battery life in portable applications
• Integrated flexible power management system with fully integrated LDO and brownout detection
• Unified clock system supporting multiple crystal sources and internal oscillators
• Hardware multiplier supporting 32-bit operations for efficient digital signal processing

Microcontrollers Applications

• Analog and digital sensor systems
• LED lighting control
• Digital power supplies
• Motor controls
• Thermostats

Microcontrollers Procurement Notes

Verify the specific package type and temperature rating against the ordering suffix IDAR. Confirm that the absence of an ADC module aligns with application requirements, as this variant differs from the MSP430F51x2 series which includes analog-to-digital conversion capabilities. Ensure compatibility with existing design files for the 38-pin TSSOP footprint.

Microcontrollers Selection Notes

Select this component when Flash capacity of 16 KB and 2 KB RAM are sufficient for the firmware size. Choose this part over the MSP430F51x2 series if analog input acquisition via an on-chip ADC is not required, allowing for potential cost or pin-count optimization. Verify that the 38-pin TSSOP package meets the PCB layout constraints compared to QFN or BGA options.

Microcontrollers Part Context

This device belongs to the MSP430F51x1 mixed-signal microcontroller family, designed for ultra-low-power sensing and measurement applications. It shares the same core architecture and peripheral set as the MSP430F5171 and MSP430F5131, differentiated primarily by its Flash memory size. The F51x1 series excludes the ADC10_A module found in the F51x2 counterparts.
