The 16 KB flash and 2 KB RAM (2K x 8) set the firmware and data budget; a capacitive touch panel with 10-15 buttons plus I²C or SPI reporting fits comfortably, but a graphics-heavy UI or large data-logging buffer would exceed the RAM ceiling. ## Peripheral set — touch, display, and wired connectivity in one chip On-chip CapSense eliminates the need for a dedicated touch controller in human-machine interfaces. The LCD drive supports direct segment display connection, saving a display driver IC. Brown-out detect, POR, and LVD handle power-supervision without an external reset IC. ## Package and board-fit — 32-QFN with exposed pad Surface-mount reflow profile follows standard lead-free QFN guidelines; the pad is electrically connected to ground, so the board layout must not short it to other nets. ## Lifecycle and supply posture No pin-compatible second source or official successor is listed, so the BOM line is tied to this order code for the production run.","metaTitle":"CY8C4024LQI-S402 Infineon PSoC 4 MCU, 24 MHz, 16 KB Flash","metaDescription":"CY8C4024LQI-S402 Infineon PSoC 4 ARM Cortex-M0+ MCU, 24 MHz, 16 KB Flash, 2 KB RAM, 27 I/O, 32-QFN.
