The Microchip 43AC4369 is a low-power, 32-bit microcontroller based on the ARM Cortex-M0+ architecture, operating at a maximum frequency of 32 MHz. It features a program memory size of 64 KB and 8 KB of SRAM. The device supports a wide operating voltage range of 1.62V to 3.63V and is rated for temperatures from -40¬8C to +105¬8C. This microcontroller includes a 12-bit ADC with up to 20 channels, a 10-bit DAC, and a Peripheral Touch Controller (PTC) capable of handling 256 channels for capacitive touch sensing. It also offers multiple serial communication interfaces, including USART, I¬=C, and SPI, along with various timers and a real-time counter. The power consumption is optimized for low energy usage, with active mode consumption as low as 50 ¬µA/MHz and 8 ¬µA when running the PTC. The 43AC4369 is packaged in a QFN-64 format, making it suitable for compact designs. Its combination of features makes it a versatile choice for applications requiring efficient processing and low power consumption.
