MindMotion Microelectronics MM32L073PT

This product features a high-performance 32-bit MCU based on the ARM® Cortex™-M0 core, with a maximum operating frequency of 48MHz, built-in high-speed memory, and rich enhanced I/O ports and peripherals connected to the external bus. The product integrates one 12-bit ADC, two comparators, one 16-bit general-purpose timer, one 32-bit general-purpose timer, three 16-bit basic timers, and one 16-bit advanced timer. It also includes standard communication interfaces: one I2C interface, two SPI interfaces, one USB interface, one CAN interface, and two UART interfaces. The product series operates at a supply voltage of 2.0V~5.5V, with an operating temperature range covering the standard grade (-40°C~+85°C) and the extended grade (-40°C~+105°C). Multiple power-saving operating modes ensure the requirements of low-power applications are met. The product is available in four package options: LQFP48, LQFP32, QFN32, and TSSOP20. Peripheral configurations may vary depending on the package type.
