Product details

512 KB Flash, 32 KB RAM — code and data budget for metrology stacks

The MSP430F67491IPEUR: 512 KB Flash (512K x 8) and 32 KB RAM (32K x 8).

4x24b sigma-delta ADC — the part's defining analog front end

Four 24-bit sigma-delta converters interface to current and voltage sensors. An additional 8-channel 10-bit ADC handles auxiliary measurements.

90 I/O and connectivity set for smart meter communication

The LCD driver peripheral built into the device drives segment displays directly, eliminating the need for a separate display controller in many meter designs.

For existing designs that already qualify this MCU, the only sourcing path is the independent market — surplus inventory, new-old-stock, or broker channels. There is no official TI successor listed for this exact order code.

Package and mounting — 128-LQFP (20×14 mm)

128-lead LQFP package with a 20 mm × 14 mm body, surface-mount. Tape & Reel suffix (IPEUR) for automated assembly.

Frequently asked questions

What is the replacement for MSP430F67491IPEUR?

Texas Instruments has not published an official direct replacement for this exact order code. For new designs, you would need to evaluate current MSP430F6xx or MSP430FRxx family devices that include sigma-delta ADC peripherals. The pinout and peripheral set will differ, so a PCB redesign is expected — there is no drop-in alternative.

Does MSP430F67491IPEUR support I2C communication?

Yes, the connectivity set includes I²C, along with SPI, UART/USART, LINbus, and IrDA interfaces. This allows direct connection to I²C-based EEPROMs, sensors, and display controllers.
