Active production, Cortex-M0 at 16 MHz — fit for cost-sensitive control
The CY8C4014LQI-412: Built around an ARM Cortex-M0 core clocked at 16 MHz, this 32-bit MCU delivers enough throughput for sensor polling, simple control loops, and I²C bus management without the cost or power of a higher-end part.
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.
