CW32L010F8P6

CW32L010 is an eFlash-based single-chip low-power microcontroller integrating an ARM® Cortex-M0+ core running up to 48MHz, high-speed embedded memory (up to 64KB FLASH and up to 4KB SRAM), and a comprehensive set of enhanced peripherals and I/O ports. All models provide a full suite of communication interfaces (2× UART, 1× SPI, and 1× I2C), a 12-bit high-speed ADC, four general-purpose and basic timers, one low-power timer, and one advanced-control PWM timer. The CW32L010 operates over a temperature range of -40°C to 85°C with a wide supply voltage of 1.62V~5.5V, and supports two low-power operating modes: Sleep and DeepSleep.
