CA32F065N5

CA32F065N5

The CA32F065N5 adopts the high - performance ARM Cortex® - M0 core, with a maximum operating frequency of 64 MHz. It is equipped with high - speed embedded flash memory (up to 64K bytes of FLASH, up to 8K bytes of SRAM, and 2K bytes of Cache), and widely integrates enhanced peripherals and I/O ports. It provides a variety of standard communication interfaces (one I2C, one CAN2.0, three serial ports, and two SPIs), two 12 - bit ADCs, one timer with 7 - channel PWM, two general - purpose timers, and two basic timers. The CA32F065L0 series operates in a temperature range of - 40 to + 85 °C and a power supply voltage range of 2.0V to 5.5V, and has a set of power - saving modes designed for low - power consumption applications.
