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.","metaTitle":"Infineon CY8C4246AZI-M443 PSoC 4 MCU, 48 MHz, 64 KB Flash","metaDescription":"Infineon CY8C4246AZI-M443 PSoC 4 MCU: ARM Cortex-M0 at 48 MHz, 64 KB Flash, 8 KB RAM, CapSense, 38 I/O, 48-LQFP.
