Addressing the need for embedded designers to have more flexibility during the design process, the latest MSPM0 Arm Cortex-M0+ MCUs from Texas Instruments help solve these challenges by providing more options, more design flexibility, and more intuitive software and tools.
Bringing 32-bit computing capability to 8- and 16-bit applications, MSPM0 MCUs for computing start with a 32-MHz Arm Cortex-M0+ CPU for simple applications and scale up to an 80-MHz CPU with hardware-accelerated math functions, including acceleration for divide, square root, multiply-accumulate, and trigonometry. The integrated successive-approximation register (SAR) analog-to-digital converter (ADC) supports monotonic 12-bit operation at up to 4 Msamples/s and 14-bit operation at up to 250 ksamples/s.
With 80 MHz of computing power at two flash wait states, MSPM0 G-series MCUs are cost-effective enough for implementation into applications such as sensorless field-oriented-control (FOC) motor-drive applications running at greater than 30 kHz, thanks to lower control-loop latency due to math acceleration, and polyphase energy-metering computation in grid infrastructures.
The MSPM0 MCUs have integrated building blocks with flexible, programmable on-chip connections, including SAR ADCs, comparators, and digital-to-analog converters (DACs). These building blocks also include zero-drift, chopper-stabilized, programmable-gain op amps with zero crossover distortion, and the integrated transimpedance amplifiers have an input bias current of 150 pA for implementing photodiode circuits.
