On Semi公司的Q32M210是精密的混合信号32位
Q32M210 is a precision, mixed−signal 32−bit microcontroller. Themicrocontroller is built on the high performance
ARMCortex_−M3 processor.
The microcontroller incorporates a highly configurable sensor interface designed to work directly with a wide range of
sensors having multiple characteristics, including specialized electrochemical sensors. The sensor interface includes dual
programmable gain amplifiers, dual 16−bit Analog−to−Digital converters, triple 10−bit Digital−to−Analog converters (for
voltage waveform generation and other applications) and three uncommitted, low−noise opamps with configurable signal
multiplexing. Flexible connectivity to external non−volatile memory, personal computers, wireless devices, LCD displays and
a wide range of other peripherals is enabled by several digital interfaces including I2C, USB (2.0 full−speed compliant) and a
high−speed SPI/SQI interface.
The microcontroller features flexible clocking options as well as intelligent failure monitoring of power and application
interruptions required by high performance, portable, battery operated applications.
All necessary clocks including an internal oscillator, real−time clock and a dedicated clock for USB operation are available
on−chip (external crystals required for RTC and USB).An embedded power management unit, which incorporates several
low power modes, allows application developers to minimize both standby and active power under a wide range of operating
conditions.
The ultra−low sleep current makes the microcontroller ideal for applications that remain inactive for long periods of time. A
large on−chip non−volatile flash memory (256 kB) combined with on−chip SRAM (48 kB) supports complex applications and
simplifies application development. The flash contains built−in hardware error checking and correction (ECC) for application
reliability. Additionally, a configurable DMA unit which supports independent peripheral−to−memory, memory−to−memory,
and memory−to− peripheral channels provides flexible, low power data transfers without processor intervention.
A suite of industry−standard development tools, hands−on training and full technical support are available to reduce design
cycle time and speed time−to−market.
