MSP430F5503IRGZR

Microcontrollers Overview

The MSP430F5503IRGZR is a mixed-signal microcontroller from Texas Instruments, featuring the MSP430 core. It integrates 64 KB of Flash memory and 8 KB of RAM within a VQFN-48 package. The device supports a maximum clock frequency of 25 MHz and operates on a supply voltage range of 1.8 V to 3.6 V. It provides 47 general-purpose I/O pins and includes multiple communication interfaces such as UART, SPI, and I2C. The component is rated for an operating temperature range of -40°C to +85°C.

Microcontrollers Feature Summary

• Integrates high-density non-volatile memory with 64 KB Flash and 8 KB RAM for robust data storage and processing.
• Supports ultra-low power consumption modes suitable for battery-operated applications.
• Includes integrated analog peripherals such as comparators and ADCs for signal conditioning.

Microcontrollers Applications

• Smart metering systems requiring reliable data logging
• Industrial control panels with limited power budgets
• Wearable health monitoring devices

Microcontrollers Procurement Notes

Verify the specific suffix IRGZR against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the VQFN-48 configuration. Cross-reference ordering information directly with Texas Instruments or authorized distributors to avoid counterfeit components.

Microcontrollers Selection Notes

Select this model when 64 KB of program memory exceeds the capacity of smaller variants like the MSP430F5501. It is appropriate for designs requiring more I/O lines than the F550x series but do not necessitate the FRAM technology found in the FR59xx family. Evaluate power requirements against the 25 MHz maximum speed capability.

Microcontrollers Part Context

This component belongs to the MSP430F5xx family, known for combining low power performance with mixed-signal capabilities. It serves as a mid-range solution within the MSP430 portfolio, bridging the gap between basic MCUs and high-performance processors. The F5503 variant specifically targets applications needing moderate memory sizes without the cost of larger packages.

Microcontrollers Replacement Considerations

Direct substitutes include other members of the MSP430F55xx series with compatible pinouts, such as the MSP430F5510. Verify memory size and peripheral availability before swapping. No official cross-reference list was identified for direct pin-to-pin replacement with different memory configurations.
