Product details

Industrial temperature grade and package fit

Rated for -40°C to 85°C ambient, this MCU is suited for factory-floor controllers, outdoor telecom line cards, and battery-powered field instruments — but not for automotive under-hood or engine-bay environments. The 28-SOIC (7.50 mm width) package is a standard footprint for wave-solder assembly and rework, and the 22 I/O lines map cleanly to a 16-pin header plus a few discrete signals. No AEC-Q100 qualification is listed, so skip it for any vehicle powertrain or chassis-domain application.

Lifecycle and sourcing — what to expect

The MSP430F123IDWR carries an EOL-hot lifecycle marker, meaning TI has announced end-of-life for this device. Production is still active per the listing, but the window for last-time buys is narrowing.

Frequently asked questions

Can I use MSP430F123IDWR as a replacement for MSP430F1232?

The MSP430F1232 is a potential migration path, but verify pin compatibility and peripheral differences against your firmware — the evidence does not confirm a drop-in replacement.

Where can I find the datasheet for MSP430F123IDWR?

The datasheet is available from Texas Instruments under the base product number MSP430F123. The full PDF covers the MSP430x1xx family electrical characteristics, memory map, and register descriptions.

What is the exact pinout of MSP430F123IDWR?

The 28-SOIC pinout follows the standard MSP430F123 pin assignment: 22 I/O lines, supply on pins 1 and 28, and the SPI/UART peripherals on alternate-function pins. Refer to the TI datasheet for the complete pin diagram.
