CW32L011K8U6

CW32L011 is an eFlash-based single-chip low-power microcontroller integrating an ARM Cortex-M0+ core with a maximum clock frequency of 96MHz, high-speed embedded memory (up to 64KB FLASH and up to 6KB SRAM), and a comprehensive set of enhanced peripherals and I/O ports. All models offer a full suite of communication interfaces (3× UART, 1× SPI, and 1× I2C), a 12-bit high-speed ADC, 5 general-purpose and basic timers, 1 low-power timer, and 1 advanced control PWM timer. The CW32L011 operates over a temperature range of -40℃ to +85℃ with a supply voltage range of 1.7V to 5.5V, supporting two low-power operating modes: Sleep and DeepSleep.
