CPW3101

A microcontroller that integrates the UFCS protocol

CPW3101 is a microcontroller compliant with the UFCS protocol. The maximum frequency is 24 MHz. It has a built-in 32KB Flash and a 2KB SRAM and supports peripherals, such as UART, I2C, and timer. Furthermore, it features high integration, interference immunity, and reliability. Its operating temperature ranges from -40 °C to 85 °C and its operating voltage ranges from 2.2 V to 5.5 V. The chip supports multiple low-power modes to meet different applications.
