Low Power LCD ML54 Series

NuMicro® ML54 Series MCU ML54MD1AE ML54LD1AE ML54SD1AE

Nuvoton NuMicro®ML54 series is an low-power microcontroller, based on 1T 8051 core, embedded 64 KB flash and 4 KB SRAM, built-in 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 ML54 series operates from 1.8V to 3.6V and-40°C to 105°C.

NuMicro® ML54 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.       

NuMicro® ML54 series features CRC、38.4 kHz and Peripheral Direct Memory Access(PDMA) controller to speed-up the data transfer and off-load the CPU loading for low-power operation. 

NuMicro® ML54 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 series 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.
