Product details

48 MHz Cortex-M0 with on-chip CapSense — the touch-centric MCU

The CY8C4246AZI-M443: Its peripheral set includes CapSense, SmartSense, LCD drive, and a brown-out detect — this part is purpose-built for touch-sensing HMI and mixed-signal control loops, not a general-purpose MCU.

38 I/O, 16-channel 12-bit ADC, and a 48-LQFP footprint

The 16-channel 12-bit SAR ADC covers analog front-end tasks like knob position, temperature, or battery voltage monitoring without an external mux. Connectivity includes I²C, SPI, UART, LIN, IrDA, and SmartCard — the LIN interface makes this part a candidate for automotive sub-bus nodes, while the I²C/SPI pair handles sensor and display links.
