MM32L052PF Overview
ARM-Cortex-M0 core and embedded storage SRAM
ARM® Cortex®-M0 processor is the latest generation of embedded ARM processor, which provides a low-cost platform and reduced pin count for the needs of MCU , Reduced system power consumption, while providing excellent computing performance and advanced interrupt system response.
ARM® Cortex®-M0 is a 32-bit RISC processor that provides additional code efficiency and exerts the high performance of the ARM core in the storage space of the usual 8- and 16-bit systems.
This product has a built-in ARM core, so it is compatible with all ARM tools and software.
Built-in flash memory The
maximum 128K bytes of built-in flash memory is used to store programs and data.
Built-in SRAM
up to 8K bytes of built-in SRAM.
Boot mode At startup, one of three boot modes can be selected through the boot pin:
• Boot from program flash memory
• Boot from system memory
•
Boot from internal SRAM bootloader (Bootloader) Stored in the system memory, the flash memory can be reprogrammed through UART1.
Low-power mode The
product supports low-power mode, which can achieve the best balance between low power consumption, short startup time, and multiple wake-up events.
Sleep mode
In sleep mode, only the CPU is stopped, and all peripherals are in working state and can wake up the CPU when an interrupt/event occurs.
The shutdown mode
can achieve the lowest power consumption without losing the SRAM and register contents. In the stop mode, the HSI oscillator and HSE crystal oscillator are turned off. The microcontroller can be woken up from stop mode by any signal configured as EXTI. The EXTI signal can be one of the 16 external I/O ports, the wake-up signal of the PVD output.
Standby mode
Standby mode can achieve the lowest power consumption of the system. This mode turns off the voltage regulator when the CPU is in deep sleep mode. All the internal power supply areas of the 1.5V part are disconnected. PLL, HSI and HSE oscillators are also closed, and can be awakened and reset by the rising edge of the WKUP pin, external reset of the NRST pin, IWDG reset or watchdog timer. The contents of SRAM and registers will be lost. Only the backup registers and standby circuits maintain power.
