ARM Cortex-M4 32-bit microcontroller -MCU

Product details

      Core :ARM® 32-bit Cortex® -M4CPU

- Maximum operating frequency of 150 MHZ, with a memory protection unit (MPU), built-in single-cycle multiplication and hardware division

- It has a DSP instruction set

      Memory

- Flash program/data storage ranging from 64 K bytes to 256K bytes

- The 18K-byte system memory can be used as a Bootloader or configured as a general user program data area at one time

- 32 K bytes of SRAM

- sLib: Set the specified primary storage area as a safe storage area for execution code. Code in this area can only be called but not read

      Clock, reset and power management

- 2.6 to 3.6 volts power supply and I/O pins

- Power-on/power-off reset (POR/PDR), Programmable Voltage monitor (PVD)

- 4 to 25 MHz oscillator

- It is equipped with a factory-calibrated 48 MHZRC oscillator (1% accuracy at 25°C and 2.5% accuracy from -40°C to +105°C), featuring an automatic clock calibration function (ACC)

- It is equipped with a 40 kHz RC oscillator with calibration
