The 16x12b SAR ADC is enough for reading multiple analog channels — think capacitive touch buttons, slider strips, or environmental sensors on a control panel. Operating from 1.71 V up to the standard 3.6 V rail, this MCU can run directly off a Li-ion cell or a 1.8 V logic supply. Infineon lists the CY8C4126AZI-M445 as Active. The PSoC 4 family has broad distribution support, so multi-year supply is realistic.","metaTitle":"CY8C4126AZI-M445 PSoC 4 ARM Cortex-M0 MCU, 24 MHz","metaDescription":"Infineon CY8C4126AZI-M445 PSoC 4 MCU: ARM Cortex-M0 at 24 MHz, 64 KB Flash, 51 I/O, 16x12b SAR ADC, 2xIDAC, CapSense, LCD drive.
