16-bit MCU with integrated 24-bit sigma-delta ADC and LCD driver
It packs 128KB of Flash program memory and 8K x 8 of RAM, with an integrated LCD driver that directly drives segment LCD panels without an external controller — a common BOM-saving feature for metering and instrumentation designs. What sets this part apart in the MSP430 portfolio is the dual ADC architecture: a 24-bit sigma-delta ADC for precision measurement channels (energy metering, weigh scales, pressure sensors) alongside a 5-channel 10-bit SAR ADC for auxiliary monitoring like temperature or voltage sensing. This eliminates a separate precision ADC IC on the bill of materials. With 52 general-purpose I/O lines in an 80-LQFP package (12x12 mm body), it offers reasonable pin density for a mixed-signal control board without jumping to a finer-pitch package.
Supply voltage and temperature grade — what they mean for deployment
Operating from 1.8V to 3.6V, this MCU can run directly from two alkaline cells or a single Li-ion battery without a regulator, though the 25MHz speed requires the higher end of that range.
Housed in an 80-LQFP package with a 12x12 mm body and 0.5 mm pitch, this is a hand-solderable QFP with reasonable trace escape under the package.
