NuMicro? M0564 series microcontroller based on the Arm? Cortex?-M0 core operates up to 72 MHz . It features adjustable VDDIO pins for specific I/O pins with a wide range of voltage from 1.8V to 5.5V for various operating voltages of external components, a unique high-speed PWM with clock frequency up to 144 MHz for precision control, and an integrated hardware divider to speed up the calculation for the control algorithms. Apart from that, the M0564 series also integrates SPROM  ( Security Protection ROM ) which provides a secure code execution area to protect the intelligent property of developers. The M0564 series is ideal for industrial control, motor control and metering applications.

The M0564 series supports the wide voltage range from 2.5V to 5.5V and temperature ranging from - 40 ℃  to 105 ℃ , up to 256 Kbytes of Flash memory, 20 Kbytes of SRAM as well as 4 Kbytes of ISP ( In-System Programming ) ROM in 48-, 64- or 100-pin packages. It also supports high immunity of 8 kV ESD ( HBM ) /4 kV EFT. It is also equipped with plenty of peripherals such as timers, watchdog timers, RTC, PDMA, EBI , UART , smart card interface, SPI , I?S, I?C , GPIO, up to 12 channels of 16-bit PWM , up to 20 channels of 12-bit ADC , analog comparator, temperature sensor, LVR ( Low Voltage Reset ) , BOD ( Brown-out Detector ) , 96-bit UID ( Unique Identification ) , and 128-bit UCID ( Unique Customer Identification ) .
