The on-chip brown-out. ## Peripheral set for touch and mixed-signal The CapSense block with SmartSense auto-tuning is the headline differentiator here: it handles capacitive touch buttons, sliders, and proximity sensing without per-board calibration, which cuts firmware tuning time and simplifies BOM consolidation across product variants. The 16-channel 12-bit SAR ADC samples at rates suitable for current-sense or temperature feedback loops, and the four 8-bit DACs can drive analog outputs or reference voltages for external comparators.","metaTitle":"Infineon CY8C4247AZI-M475 PSoC 4 MCU, 48 MHz Cortex-M0","metaDescription":"Infineon CY8C4247AZI-M475 PSoC 4 MCU: ARM Cortex-M0 at 48 MHz, 128KB Flash, 51 I/O, CapSense+SmartSense, -40 to 85°C.

The CY8C4247LQI-BL473 comes in a QFN package with 36 I/O, while the CY8C4247AZI-M475 is a 64-pin TQFP with 51 I/O. The core, Flash size, and 48 MHz clock are the same, but the pinout and footprint differ. If you need the same package with Bluetooth, the BL473 is the peer; if you need the extra I/O and the TQFP footprint, stick with the M475."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C4247AZI-M475","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C4247AZI-M475 when reusing this data.
