Product details

16 MHz ARM Cortex-M0 for automotive control tasks

The internal oscillator eliminates the crystal and its two load capacitors, saving board area and BOM cost in high-vibration environments. A single I²C interface provides connectivity to sensors, EEPROMs, or a body-controller module.

Temperature grade and package — built for under-hood and cabin

The 16 KB Flash and 2 KB RAM are sized for control-oriented firmware: reading a temperature sensor over I²C, driving a PWM fan or pump, and managing a watchdog timeout. The 7-bit and 8-bit DAC outputs can generate analog setpoints or simple waveforms without an external DAC.

Frequently asked questions

What is the closest functional second-source for CY8C4014SXS-421Z?

The CY8C4245LQI-483 is a higher-performance PSoC 4 sibling with a 48 MHz core, more I/O (34), and additional connectivity (SPI, UART, LINbus), but it comes in a 40-QFN package and has a narrower temperature range (85°C). It is not a pin-compatible drop-in; a board redesign and firmware port would be required.

Is CY8C4014SXS-421Z RoHS compliant?

Yes, the CY8C4014SXS-421Z is ROHS3 compliant, meeting the latest EU RoHS directive requirements.
