What sets this part apart from a plain Cortex-M0 is the integrated CapSense block — no external capacitive-touch controller needed for up to 24 touch channels — plus a 12-bit SAR ADC (8-channel) and two current-output IDACs. The brown-out detect, POR, and LVD supervisors run autonomously, so the core can sleep through supply monitoring. ## Supply flexibility and serial connectivity Serial interfaces include I²C, SPI, UART/USART, LIN, IrDA, SmartCard, and Microwire — the SSP block handles synchronous protocols, while the UART supports LIN break generation for automotive sensor nodes. The 24 GPIOs in a 28-pin package mean only four pins are tied to power and ground; every other pin is usable as I/O or a dedicated function.","metaTitle":"CY8C4124PVI-442 PSoC 4 MCU, 24 MHz Cortex-M0, 28-SSOP","metaDescription":"CY8C4124PVI-442 PSoC 4 ARM Cortex-M0 MCU, 24 MHz, 16 KB flash, 4 KB SRAM, CapSense, 28-SSOP.
