16 MHz Cortex-M0 with 16 KB Flash — entry-level PSoC 4 for I²C-centric control
The part integrates a brown-out detect, POR, PWM, and WDT peripherals, plus a 1x7-bit and 1x8-bit DAC, and communicates via I²C. It comes in a 24-QFN package with exposed pad, offering 20 GPIOs.
I²C-only serial interface — design-in constraint vs. richer siblings
Unlike the CY8C4245LQI-483 which adds SPI, UART/USART, IrDA, LINbus, and SmartCard interfaces, the CY8C4014LQI-422T is limited to I²C for serial communication. This makes it a fit for simple sensor aggregation, I²C bus extenders, or single-protocol control nodes, but not for designs needing UART debug output or SPI flash expansion without bit-banging GPIO.
However, the part is listed as RoHS non-compliant, which may restrict its use in markets with strict RoHS enforcement or require an exemption declaration.
