MM32F0040B1N

The MM32F0040 microcontroller is based on the Arm Cortex-M0 core, operating at up to 72MHz. It integrates 32KB of high-speed flash memory along with a rich set of I/O ports and peripheral modules. The product includes 1 x 12-bit ADC, 1 x comparator, 1 x 16-bit advanced timer, 1 x 16-bit and 1 x 32-bit general-purpose timer, 3 x 16-bit basic timers, and standard communication interfaces: 1 x I2C, 1 x SPI or I2S, and 3 x UART. The product series operates at 2.0V ~ 5.5V, with an ambient operating temperature range of -40℃ ~ +85℃ for the industrial grade and -40℃ ~ +105℃ for the extended industrial grade (suffix V). Multiple built-in low-power operating modes meet the requirements of low-power applications. This rich peripheral configuration makes the microcontroller suitable for a wide range of applications. The product is available in QFN20 and TSSOP20 packages.
