MSP430F67451IPEU

Microcontrollers Overview

The MSP430F67451IPEU is a mixed-signal microcontroller from the Texas Instruments MSP430F674x1 family, designed for metering applications. It features an MSP430 core with a maximum clock frequency of 25 MHz and operates within a supply voltage range of 1.8 V to 3.6 V. The device includes 128 kB of Flash program memory and 16 kB of SRAM data RAM. It provides 90 I/O pins and integrates multiple communication interfaces including I2C, SPI, and UART. The ADC resolution supports both 10-bit and 24-bit modes. Encased in a LQFP-128 package, it functions reliably between -40°C and +85°C.

Microcontrollers Feature Summary

• Integrated 24-bit Sigma-Delta ADC suitable for high-precision metering tasks
• Supports LCD driving and Real-Time Clock functionality
• Includes four 16-bit timers/counters for precise timing control
• Features UART-based Bootloader System (BSL) for firmware updates

Microcontrollers Applications

• Smart electricity metering systems
• Gas and water utility meters
• Industrial energy monitoring devices
• Embedded measurement instrumentation

Microcontrollers Procurement Notes

Verify the specific suffix 'IPEU' corresponds to the LQFP-128 package variant rather than other pin counts or packages like LQFP-100. Confirm that the 'A' designation in similar part numbers does not indicate a different revision if sourcing substitutes. Ensure moisture sensitivity handling protocols are followed during assembly as indicated by the component specifications.

Microcontrollers Selection Notes

Select this component when a 128-pin interface is required for extensive peripheral connectivity in metering designs. Compare against the MSP430F67451AIPEU which utilizes a LQFP-100 package; choose based on available PCB space and I/O requirements. Consider the MSP430F67651 series if higher performance variants within the same family are needed.

Microcontrollers Part Context

This microcontroller belongs to the MSP430F674x1 mixed-signal microcontroller family. It shares architectural similarities with the MSP430F67651 and MSP430F677x1 series, differing primarily in memory sizes and specific feature sets tailored for cost-effective metering solutions while maintaining low power consumption characteristics.

Microcontrollers Replacement Considerations

The MSP430F67451AIPEU serves as a direct functional substitute with identical electrical specifications but utilizes a LQFP-100 package instead of LQFP-128. Verify pin compatibility before substitution.
