M256SE3AE Description

Short technical summary and product information.

The Nuvoton M256SE3AE is a 32-bit microcontroller built on the Arm Cortex-M23 core with Armv8-M architecture. It is designed for low-power applications and features an integrated COM/SEG LCD driver and capacitive touch sensing capabilities.

 

This microcontroller runs at speeds up to 48 MHz and is equipped with 128 KB of Flash memory and 16 KB of SRAM. It supports a wide operating voltage range of 1.75V to 5.5V and offers 5V I/O tolerance. The operating temperature range is -40°C to +105°C.

 

The M256SE3AE includes a versatile COM/SEG LCD driver supporting various configurations and a built-in charge pump for LCD panels operating between 3V and 5V. It also provides up to 16 touch-keys for capacitive sensing.

 

Connectivity options include multiple UART, SPI/I²S, I²C, and USB interfaces, along with PDMA channels and PWM outputs, making it suitable for integrating comprehensive external modules. The device also integrates a 12-bit ADC with 16 channels and a temperature sensor.

 

It is available in a 64-LQFP package (7mm x 7mm), designed for surface mounting. The pin-compatible nature of the package facilitates system design and part changes.
