The NuMicro M0564 series provides an unique high-speed PWM with clock frequency up to 144 MHz for precision control, and an integrated hardware divider to speed up algorithm calculation. The large Flash of 256 KB, three sets of USCI and high noise immunity of 8kV ESD and 4kV EFT are ideal for the smart metering applications. The 12-bit ADC with up to 20 channels can be used to get the sensing data for use with the high-end circuit breaker that usually requires multiple ADC channels for voltage measurement.

The M0564 series also supports VAI for specific I/O pins to support wide-range interface voltage from 1.8V to 5.5V for various operating voltages of external components to directly connect to the M0564 series without the need of extra level-shifters. Apart from that, it also integrates the SPROM (Security Protection ROM), which provides a secure code execution area to protect the intellectual property of developers.

The NuMicro M0564 series supports the wide voltage range from 2.5V to 5.5V and temperature from -40℃ to 105℃, up to 256 KB of Flash memory, 20 KB of SRAM as well as 4 KB of ISP (In-System Programming) ROM. It is also equipped with plenty of peripherals such as timers, watchdog timers, RTC,EBI, smart card interface, I²S, two sets of SPI, two sets of I²C, 5 channels of PDMA, three sets of USCI, three sets of UARTs, analog comparator, temperature sensor, LVR (Low Voltage Reset), BOD (Brown-out Detector), 96-bit UID (Unique Identification), and 128-bit UCID (Unique Customer Identification). The M0564 series is available in LQFP48, LQFP64 and LQFP100 packages.
