CW32L083RBT6

CW32L083 is a single-chip low-power microcontroller based on eFlash, integrating an ARM® Cortex®-M0+ core with a main frequency of up to 64MHz, high-speed embedded memory (up to 256K bytes of FLASH and up to 24K bytes of SRAM), and a series of comprehensive enhanced peripherals and I/O ports. All models provide a full set of communication interfaces (six UARTs, two SPIs, and two I2Cs), a 12-bit high-speed ADC, seven groups of general and basic timers, a group of low-power timers, and a group of advanced control PWM timers. CW32L083 can operate in a temperature range of -40℃ to 85℃ and has a wide supply voltage range of 1.65V to 5.5V. It supports two low-power operating modes: Sleep and DeepSleep. CW32L083 offers four different package forms: LQFP100, LQFP80, LQFP64 (10mm x 10mm), and LQFP64 (7mm x 7mm). The functions that can be achieved by products in different packages vary.
