Product details

25 MHz MSP430 CPUXV2 with integrated metrology peripherals

The MSP430F67491AIPEU integrates four 24-bit sigma-delta ADCs and an LCD driver, reducing external components for three-phase metering designs.

What the 4x24-bit sigma-delta ADC and LCD controller mean for the BOM

The four 24-bit sigma-delta converters sample voltage and current channels simultaneously for power calculation in a three-phase meter, eliminating external ADC or analog front-end.

Industrial temperature range and connectivity

The 90 I/O pins support tamper switches, relay drivers, and optocoupler interfaces. Connectivity includes I²C, SPI, UART, IrDA, and LINbus for external RF module or PLC modem.

Frequently asked questions

Does MSP430F67491AIPEU have an LCD controller?

Yes, it integrates an LCD driver capable of driving segment displays directly, without an external controller chip. This is one of the key peripherals that distinguishes the F6xx series from the smaller MSP430 families.
