Product details

Three 24-bit sigma-delta ADCs — built for polyphase metering

What sets it apart for energy-monitoring designs is the analog front end: three independent 24-bit sigma-delta ADCs (3x24b) plus an 8-channel 10-bit SAR ADC. That ADC array directly supports simultaneous voltage and current sampling on each phase of a three-phase power line, with the 24-bit resolution capturing the dynamic range needed for Class 0.5 or better accuracy.

Program memory is 64 KB of Flash (64K x 8), with 4K x 8 of RAM. For a metering application the Flash holds the calibration constants, metering algorithm, and communication stack; the RAM handles the real-time sample buffers and intermediate math. The 4 KB RAM is tight if you are logging waveform captures — plan for a circular buffer in Flash or an external serial SRAM if you need extended recording.

The integrated LCD driver (up to 160 segments) directly drives the display panel, saving a separate controller.

Frequently asked questions

What is the flash memory size of MSP430F6733IPZ?

Program memory is 64 KB (64K x 8) of Flash, with 4K x 8 of RAM.

Does MSP430F6733IPZ have an LCD controller?

Yes — the peripheral set includes an LCD driver capable of driving up to 160 segments directly, eliminating the need for a separate display controller.

Can MSP430F6733IPZ replace MSP430F6732IPZ?

The MSP430F6733IPZ is a higher-density sibling of the MSP430F6732IPZ, sharing the same 100-LQFP footprint and peripheral set. The primary difference is program memory — 64 KB Flash versus the 32 KB on the MSP430F6732IPZ — so a direct replacement is possible if the firmware fits within the smaller Flash of the original device.
