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.

Industrial temperature range and peripheral set

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.
