Against the backdrop of intensified competition in the global MCU market and accelerated domestic substitution, embedded devices have placed unprecedented demands on the performance, power consumption, reliability, and cost-effectiveness of core control chips. To adapt to market competition, on July 16, 2025, Wuhan Xinyuan Semiconductor officially launched a new member of the low-power microcontroller family based on the CW32L01x series: the CW32L012 series products

CW32L012 is based on ARM Cortex-M0+core, with a clock frequency of up to 96MHz. It also integrates CORDIC hardware unit and Extended Arithmetic Unit (EAU), which can provide hardware acceleration for some mathematical functions and arithmetic operations. It is particularly suitable for applications such as motor control, power supply, metering, signal processing, etc.

Meanwhile, CW32L012 is a single-chip low-power microcontroller based on eFlash, integrating dual 12 bit ADCs and dual 12 bit DACs, and equipped with flexible dual rail to rail operational amplifiers, which can achieve complete mixed signal digital processing on a single chip.

CW32L012 can operate within a temperature range of -40 ℃~+85 ℃, with a power supply voltage width of 1.7V~5.5V. Supports two low-power operating modes, Sleep and DeepSleep. The internal block diagram is shown in the following figure:

CW32L012 provides two different packaging forms, and the basic configuration is shown in the table below:
