Product details

Metering-grade MCU with integrated sigma-delta ADC

MSP430F67751IPEU integrates seven 24-bit sigma-delta ADCs and an LCD driver.

Peripheral set for polyphase measurement

The seven independent 24-bit sigma-delta converters enable simultaneous sampling of voltage and current on each phase of a three-phase system plus neutral, eliminating the need for external analog front-ends or multiplexed inputs. The on-chip LCD driver directly drives segment displays for energy totals, line frequency, and power factor — useful in panel meters and submeters where a separate display controller would add BOM cost and board area.

Frequently asked questions

What is the difference between MSP430F67751IPEU and MSP430F67751IR?

The MSP430F67751IPEU is in a 128-LQFP (20×14 mm) package, while the MSP430F67751IR is in a 128-LQFP (14×14 mm) package. Both share the same core, memory, and peripheral set, but the different package dimensions affect PCB footprint and thermal dissipation.
