Description
MM32F103xCxE(named as ”the device” throughout this document) is ARM® CortexTM-M3
32-bit RISC core based micro controller family. The device has high speed embedded
memory and the CPU, memory and AHB bus subsystem speed can attain up to 168MHZ.
The device also has integrated with extensive range of enhanced I/Os, two APB buses
peripherals, 1 12-bit ADC, 2 Comparators, 2 general purpose 16-bit timers, 2 general purpose 32-bit timers, 2 Basic timers, 2 Advanced 16-bit timers, and standard communication
interfaces device: 2 I2Cs, 3 SPIs, 1 USB, 1 CAN, 1 SDIO, and 8 UARTs.
The device works between 2.0V to 5.5V range. The normal temperature for the device
is -40◦C to +85◦C and -40◦C to +105◦C extended temperature range devices are also
available upon ordering. A comprehensive set of power-saving mode allows the design
of low-power applications.
The devices are available in 5 different packages: LQFP100, LQFP64, LQFP48, LQFP32
and QFN32. Depending on the device chosen, different sets of peripherals are included.
