Description

The NuMicro M254KG6AE 32-bit microcontroller is based on Arm Cortex-M23 core using Armv8-M architecture with COM/SEG LCD driver. It runs up to 48 MHz and features 256 Kbytes Flash memory, 32 Kbytets SRAM, 1.75V ~ 5.5V wide operating voltage, 5V I/O tolerance, and -40℃ to +105℃ operating temperature.

M254KG6AE includes a 4 x 48, 6 x 46, 8 x 44 COM/SEG LCD driver with selectable bias voltage and duty, and it also built-in charge-pump to support 3V to 5V wide voltage of LCD panel

M254KG6AE provides plenty of peripherals such as Timers, Watchdog Timers, RTC, 8 channels of PDMA, 4 sets of UART, 2 setof Universal Serial Control Interface (USCI), 2 sets of SPI/ I²S, 2 sets of I²C, 1 set of ISO-7816-3, 12 channels of basic PWM, making it highly suitable for connecting comprehensive external modules. It also integrates high performance analog circuit, such as 16 channels of 12-bit 730 kSPS ADC, 2 sets of 12-bit DAC for external voltage reference, and a temperature sensor to reduce external components.

Supported packages LQFP128 (14 mm x 14 mm) with pin-compatible for different part numbers make the system design and parts change easily.
