MM32F0144C6P

The MM32F0140 microcontroller features an Arm Cortex®-M0 core with a maximum operating frequency of 72MHz. It integrates 64KB of high-speed flash memory along with extensive I/O ports and peripheral modules, including: one 12-bit ADC, one comparator, one 16-bit advanced timer, one 16-bit and one 32-bit general-purpose timer, three 16-bit basic timers, and standard communication interfaces: one I2C, two SPI/I2S, three UART, and one FlexCAN. The product family operates at 2.0V~5.5V, with an ambient temperature range of -40°C~+85°C (industrial grade) and -40°C~+105°C (extended industrial grade, suffix V). Multiple built-in low-power modes meet the requirements of power-sensitive applications. This rich peripheral set makes the microcontroller suitable for a wide range of applications. The product is available in LQFP48, LQFP32, QFN32, and TSSOP20 packages.
