Mixed signal mcu targets portable sensing applications

1 min read

ON Semiconductor has introduced the first in a new series of mixed signal microcontrollers for precision measurement and monitoring. Designed for use in portable sensing applications and built with the ARM Cortex-M3 processor, ON claims the Q32M210 can provide high precision performance and predictable operation with strong power efficiency.

Operating at less than 400MHz, the mcu features dual 16bit ADCs, a voltage reference, triple 10bit DACs and 32bit core. It also features 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. All critical functions are included on the chip, including a real time clock, power management, on chip low resistance switches, uncommitted op amps, a precision voltage reference and an RC oscillator. Housed in a 140pin TLLGA package, the microcontroller supports a range of data interfaces including UART, dual-SPI/SQI, I2C, I2S and a usb 2.0 full speed interface with integrated PHY. "The Q32M210 microcontroller represents a significant step forward in precision mixed signal control," said Todd Schneider, vice president for ON Semiconductor's conversion and control technologies product line. "We believe the combination of a highly configurable analogue front end with a proven 32bit core offering high accuracy, predictable operation and low power operation coupled with a wide range of standard interfaces is extremely compelling for a wide range of battery powered sensing equipment."
