The 48 MHz clock keeps the core fast enough for real-time control tasks like reading a 12-bit SAR ADC at 1 Msps and updating a PWM period within one control cycle, without the power penalty of a Cortex-M4. ## Integrated analog and serial connectivity — sensor-fusion ready The CY8C4245AXI-473 packs an 8-channel 12-bit SAR ADC and two current-mode IDAC outputs, which means you can read analog sensors (thermistors, strain gauges, photodiodes) and drive a programmable current source for sensor excitation or closed-loop biasing without external DACs.","metaTitle":"CY8C4245AXI-473 PSoC 4 ARM Cortex-M0 MCU, 48 MHz","metaDescription":"Infineon CY8C4245AXI-473 PSoC 4 MCU: 32-bit ARM Cortex-M0 at 48 MHz, 32 KB Flash, 8x12b SAR ADC, 2x IDAC, 36 I/O in 44-TQFP.

If you need the TQFP footprint and the full 36 I/O count, the CY8C4245AXI-473 is the correct fit.
