On Semiconductor has introduced the Q32M210, the first in a family of mixed-signal microcontrollers (MCUs) for precision measurement and monitoring applications. Designed with an ARM Cortex M3 processor core, the device features dual 16-bit ADCs, a highly accurate voltage reference, and triple 10-bit DACs.

Predictable operation is a key aspect of the device, a spec that’s required for medical applications, like patient monitors, wireless ECGs, and blood glucose meters. Fetaures include on-chip power supervision with dedicated brown-out protection circuitry and low battery detection.

Integrated error checking and correction circuitry monitors the on-chip flash memory, detecting and correcting single bit errors and alerting when larger errors are detected.

The Q32M210 operates at less than 400 µA/MHz. It’s housed in a 140-pin TLLGA package. Samples are available for $4.99 in 10,000-unit quantites. An evaluation and development kit is also available.
