MSP430FG477IPN

Microcontrollers Overview

The MSP430FG477IPN is a 16-bit ultra-low-power microcontroller from the Texas Instruments MSP430 family, housed in an LQFP-80 package. It features 32 kB of Flash program memory and 2 kB of RAM. The device supports a maximum clock frequency of 16 MHz and operates within a supply voltage range of 1.8 V to 3.6 V. It includes a 16-bit ADC with five channels and provides 48 I/O pins. Communication interfaces include I2C, SPI, UART, and USCI. The component functions reliably across an operating temperature range of -40°C to +85°C.

Microcontrollers Feature Summary

• Integrates a 16-bit ADC with five dedicated channels for analog signal acquisition.
• Supports multiple communication protocols including I2C, SPI, UART, and USCI.
• Designed for ultra-low-power applications using the MSP430 core architecture.

Microcontrollers Applications

• Low-power sensor interface systems
• Industrial control units requiring serial communication
• Battery-operated instrumentation devices

Microcontrollers Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the LQFP-80 configuration. Check moisture sensitivity levels for proper storage and handling requirements during assembly processes.

Microcontrollers Selection Notes

Select this component when a balance of moderate Flash capacity and high-resolution analog input is required. The inclusion of USCI simplifies design for versatile serial communication needs. Consider the 16-bit data bus width for efficient processing of mixed-signal data without external buffering.

Microcontrollers Part Context

This part belongs to the MSP430FG47x series, which targets mixed-signal embedded control applications. It shares architectural similarities with other members of the 4-series family but offers distinct memory and peripheral configurations tailored for cost-sensitive, power-constrained environments.

Microcontrollers Replacement Considerations

Check for direct pin-compatible upgrades within the MSP430F4xx or MSP430FRxx families if higher memory density is needed. Verify that alternative parts support the same LQFP-80 footprint and voltage ranges.
