The 55 GPIOs in a 68-QFN package (8x8 mm) let you connect multiple sensors, a keypad, and a display without resorting to a port expander, but the 0.5 mm pitch demands a 4-layer board for clean fan-out and decoupling. ## Analog front-end and peripheral mix A 16-channel 12-bit SAR ADC and four 8-bit DACs provide enough analog capture and output for a multi-sensor control panel — the ADC scans touch electrodes, temperature, and voltage dividers, while the DACs drive analog indicators or bias references. On-chip CapSense with SmartSense auto-tuning eliminates the need for external capacitive-sensing ICs; the LCD drive can directly segment a glass panel without a separate controller, saving BOM cost and board area.","metaTitle":"CY8C4246LTI-M475 Infineon MCU, 48 MHz, 64 KB Flash, 55 I/O","metaDescription":"Active-production CY8C4246LTI-M475 from Infineon: ARM Cortex-M0, 48 MHz, 64 KB flash, 55 GPIO, 16-ch ADC, industrial -40°C to 85°C.
