MSP430F438IPN

Microcontrollers Overview

The MSP430F438IPN is a 16-bit mixed-signal microcontroller from the Texas Instruments MSP430 family, housed in an LQFP-80 package. It features 48 kB of Flash program memory and 2 kB of data 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 USART interfaces and two timer/counters. The component functions across a temperature range of -40°C to +85°C.

Microcontrollers Feature Summary

• Integrates mixed-signal capabilities with a 16-bit RISC architecture for efficient processing.
• Provides non-volatile Flash memory for program storage and volatile RAM for data handling.
• Supports serial communication via USART interfaces for system connectivity.

Microcontrollers Applications

• Low-power embedded control systems
• Industrial monitoring applications
• Consumer electronics requiring mixed-signal processing

Microcontrollers Procurement Notes

Verify the specific suffix IPN corresponds to the tray packaging configuration when ordering. Confirm that the required operating temperature range aligns with the commercial grade specifications. Ensure compatibility with the target PCB footprint for the LQFP-80 package. Check for any moisture sensitivity level requirements during assembly processes.

Microcontrollers Selection Notes

Select this model when 48 kB of Flash and 2 kB of RAM are sufficient for the application logic. Consider the 16 MHz maximum clock speed for timing requirements. Evaluate the availability of 48 I/O pins against interface needs. Compare against variants like the F439 if higher memory capacity or different peripheral configurations are necessary.

Microcontrollers Part Context

This component belongs to the MSP430F43x series, designed for low-power mixed-signal applications. It shares architectural similarities with other members of the 4 Series, such as the MSP430F437 and MSP430F436, differing primarily in memory sizes and specific peripheral implementations within the same package family.

Microcontrollers Replacement Considerations

The MSP430A095IPN is documented as an alias for the MSP430FG438IPN, which shares identical memory and pinout specifications. Verify functional equivalence before substitution.
