MSP430F6733AIPZ — 16-bit MCU for metering and precision sensing
The 16-bit MCU runs at 25 MHz. The dual ADC block has eight 10-bit channels and three 24-bit sigma-delta channels.
The 25 MHz clock rate is the ceiling for the pipeline. For a metering application running a 24-bit ADC and a Modbus stack, this is enough headroom to handle the math without a co-processor.
Dual ADC — 24-bit sigma-delta for metrology
The three 24-bit sigma-delta ADCs support simultaneous sampling, which is critical for polyphase energy measurement. The eight 10-bit channels handle auxiliary signals like temperature or tamper detection.
The 100-LQFP package (14x14 mm body) is a surface-mount footprint.
