MSP430F6734AIPNR

Microcontrollers Overview

The MSP430F6734AIPNR is a mixed-signal microcontroller from the Texas Instruments MSP430F673x family, housed in an 80-pin LQFP package. It features a 16-bit 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 96 kB of non-volatile memory, 4 kB of RAM, and a 24-bit Sigma-Delta ADC. It supports three UARTs, four SPI channels, one I2C interface, and four 16-bit timers.

Microcontrollers Feature Summary

• Integrates a high-resolution 24-bit Sigma-Delta analog-to-digital converter for precision signal acquisition.
• Includes dedicated hardware peripherals such as an LCD controller and a real-time clock.
• Provides multiple communication interfaces including UART, SPI, and I2C for system connectivity.

Microcontrollers Applications

• Single-phase metering systems
• Industrial control applications requiring precise analog measurement
• Embedded devices utilizing LCD displays

Microcontrollers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature rating. Ensure the ordering part number matches the exact memory configuration and peripheral set required for the design. Cross-reference the manufacturer's latest datasheet to validate RoHS compliance and current production status before finalizing procurement.

Microcontrollers Selection Notes

Select this component when a balance of moderate flash memory and high-precision analog input is required. The 24-bit ADC distinguishes it from standard 10-bit variants in the same series. Consider the 80-pin LQFP footprint for PCB layout constraints and verify that the 4 kB RAM suffices for the application's stack and data requirements.

Microcontrollers Part Context

This microcontroller belongs to the MSP430F673x mixed-signal family, designed for low-power embedded applications. It shares architectural similarities with the MSP430F6730A and MSP430F6733A but offers distinct memory capacities. The device targets cost-sensitive designs needing robust analog capabilities without external converters.

Microcontrollers Replacement Considerations

The MSP430F6734IPZ serves as a pin-compatible leaded alternative. Verify package dimensions and thermal characteristics when substituting surface-mount variants with through-hole options or vice versa.
