MINI55LDE

The Nuvoton MINI55LDE is a microcontroller based on the Arm Cortex-M0 core, capable of operating at speeds up to 48 MHz. It is designed for control applications and features a 16-bit high-resolution PWM with a frequency up to 48 MHz, suitable for switch control and protection in home appliances. A built-in 32-bit hardware divider accelerates control algorithm calculations.

This microcontroller supports a wide voltage range from 2.1V to 5.5V and operates within a temperature range of -40°C to 105°C. It offers 17.5 Kbytes of application Flash memory (APROM), 2 Kbytes of loader Flash (ISP LDROM), and 2 Kbytes of embedded SRAM. The MINI55LDE is housed in a 48-LQFP package (7x7 mm) and supports surface mount installation.

Key peripherals include two UARTs, one SPI, one I²C, multiple PWM generators, a Watchdog Timer, Analog Comparator, and a Brown-out Detector. It also includes a 10-bit SAR ADC with up to 12 analog input channels. The device boasts exceptional noise immunity with 6 kV ESD (HBM) and 3 kV EFT protection.

Target applications for the MINI55LDE include home appliances, wireless chargers, and industrial control systems, as well as Programmable Logic Control (PLC) and I/O extension applications.
