Nuvoton NuMicro®ML56 series is is an low-power microcontroller, based on 1T 8051 core, embedded 64 KB flash and 4 KB SRAM, built-in capacitive touch key and LCD driver, running up to 24 MHz. For low power operation, it runs less than 100 µA/MHz in normal run mode, and power down current is below 2 µA with LCD panel display on. The ML56 series operates from 1.8V to 3.6V and -40°C to 105°C. 

NuMicro® ML56 series integrated capacitive touch sensing circuit with enhanced touch key controller, supporting up to 14 independent touch channels with low power characteristics, water proof and high noise resistance features.  The touch key can be one of the wake up source, and has conducted 10-Vrms noise immunity, which makes it especially suitable for home appliances and industrial control. Moreover, Nuvoton provides a complete development tool, and touch library to shorten customer’s developing and mass production by easy callibration of touch key functions. 

NuMicro® ML56 series builts in 4 COM x 32 SEG, 6 COM x 30 SEG, 8 COM x 28 SEG LCD controller to drive up to 224 dots, and supports the Type-A and Type-B LCD panel. It provides two VLCD input sources, one is external voltage, and another is internal charge pump, The internal charge pump keeps the VLCD constant voltage to maintain the display quality of the LCD panel while VDD input changes. There are two VLCD driving modes, external capacitor mode and internal resistor mode. The external capacitor mode with strong driving current to support large size panel; the internal resistor mode drives small size panel and reduces power consumption. 

For the requirment from safety liabry, the ML54 series features CRC-8 checksum to realize power-on and regualr self-test of Flash memory, it also provides up to 4 channels of Peripheral Direct Memory Access(PDMA) controller to speed-up the data transfer and off-load the CPU loading. For lighting control, the PDMA accompanies with UART or SPI interface can transmit the data continuosly. 

NuMicro® ML56 series is more than a 8-bit microcontroller, which equipped with enhenced analog features, such as 12-bit 500k SPS ADC, up to 2ch of comparators , 4-level of internal voltage reference for ADC and ACMP; the ML54 serie http:// s built-in RTC to record data and show calendar while in power-down mode, it also provides three packages: LQFP 44, LQFP48, and LQFP64 with pin-compatible to NuMicro 32-bit microcontrollers to simplify the system design and change parts easily.
