ON Semiconductor has introduced its first range of ARM Cortex-M3 based mixed-signal microcontrollers designed for precision medical sensing applications.
The Q32M210 devices feature dual 16-bit ADCs, a highly accurate voltage reference, triple 10-bit DACs and 32-bit core.
The supplier says these on-chip ADCs offer true 16-bit performance “unlike typical converters, where non-linearity and noise can reduce the number of effective bits”.
Low power operation is less than 400µA/MHz and there is a flexible clocking architecture and intelligent power-supply monitoring.
The configurable analogue front-end has a programmable 32-bit core and there is 256kbyte of flash memory.
All critical functions are on the chip, including a real-time clock, power management, a 112-segment LCD interface, on-chip low resistance switches, uncommitted op-amps, a precision voltage reference (< 50 PPM/°C) and an RC oscillator to reduce complexity and external component count—helping designers achieve an overall lower system cost.
The chips are housed in a 140-pin TLLGA packages. 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.
