With 16 KB of program memory and 2 KB of SRAM, the CY8C4014LQI-412 fits applications where the firmware image stays under ~14 KB after the HAL and bootloader overhead, leaving a few KB for the stack and variables. The 20 GPIOs in a 24-pin QFN package mean every pin except Vdd, Vss, and the reset line is available as an I/O — useful for keypad scanning, LED driving, or parallel sensor readout in a small footprint. Industrial temperature grade (-40°C to 85°C) covers outdoor enclosures, unheated factory floors, and automotive cabin-adjacent modules where the ambient stays within that band. ## On-chip DACs and I²C — analog output without extra ICs The integrated 7-bit and 8-bit DACs generate analog reference voltages or simple waveforms directly from the MCU pins, saving a separate converter IC on the BOM — useful for trimming sensor offsets or driving a piezo buzzer. I²C connectivity supports daisy-chaining temperature sensors, EEPROMs, or port expanders on a two-wire bus, keeping the pin count low while adding peripheral flexibility. ## Package and compliance — 24-QFN with exposed pad, ROHS3 ROHS3 compliant per Infineon's lifecycle record, so the part meets EU and global substance restrictions without exemption declarations needed on the shipping documentation.","metaTitle":"CY8C4014LQI-412 Infineon PSOC 4 MCU, 16 MHz, 16 KB Flash","metaDescription":"CY8C4014LQI-412 Infineon PSOC 4 ARM Cortex-M0 MCU, 16 MHz, 16 KB Flash, 2 KB RAM, 20 I/O, 1.71-5.5 V, -40 to 85°C.
