Product details

The Texas Instruments MSP430FE427AIPMR is a 16-bit MSP430 MCU built around the MSP430 CPU16 core, clocked at 8.4 MHz. The industrial temperature range (-40°C to 85°C) and 1.8 V to 3.6 V supply make it a fit for utility meters, sub-metering gateways, and factory-floor power-quality loggers where the board lives in an outdoor or unconditioned enclosure.

Integration note: package and peripherals

The 14 general-purpose I/O lines are shared with the LCD segment outputs and the SPI/UART interface — plan the pin allocation before layout. The three 16-bit sigma-delta ADCs are the main event: they are differential inputs, so the analog front-end needs anti-aliasing filters and a clean ground plane to preserve the 16-bit noise floor.

Frequently asked questions

Where can I buy MSP430FE427AIPMR and how do I get a price?

The MSP430FE427AIPMR is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is MSP430FE427AIPMR's listed speed (8.4 MHz) on this component line?

The MSP430FE427AIPMR is rated for an 8.4 MHz core clock. This is the maximum CPU speed; the internal oscillator can generate it without an external crystal, though the sigma-delta ADCs benefit from a clean clock source for best noise performance.

What compliance documentation does this brand provide for MSP430FE427AIPMR?

Texas Instruments provides RoHS and REACH compliance documentation for the MSP430FE427AIPMR. The part is supplied in a Tape & Reel package that is lead-free and RoHS-compliant per TI's standard material declarations.
