Its headline feature is the integrated CapSense and SmartSense peripheral block, which handles capacitive touch sensing directly — no external touch controller IC needed. The wide supply range from 1.71 V to 5.5 V lets it run from a single 3.3 V or 5 V rail, simplifying the power tree in mixed-voltage designs. With 53 I/O, USB connectivity, and a 12-bit SAR ADC (16 channels) plus four 8-bit DACs, this part targets human-machine interface (HMI) panels, appliance control boards, and industrial sensor nodes that need touch input alongside general-purpose MCU tasks. ## Industrial temperature grade and package — board-level fit Rated for -40°C to 85°C ambient, the CY8C4247AZI-L475 suits factory-floor automation, outdoor telecom cabinets, and under-hood automotive cabin applications. It ships in a 64-LQFP package (10x10 mm body, 0.5 mm pitch) — a common footprint for medium-density MCU boards. The 53 available I/O give enough headroom for a parallel LCD data bus, a row-column keypad matrix, or a bank of optocoupler inputs without needing a port expander. ## CapSense block — no separate touch controller needed The integrated CapSense and SmartSense peripheral handles self-capacitance and mutual-capacitance touch sensing. SmartSense auto-tunes the sensor parameters during operation, which compensates for overlay thickness variation and environmental drift. For a BOM engineer, this means one less IC to qualify and one less firmware stack to maintain — the touch library runs on the same Cortex-M0 core that handles application code. ## Active lifecycle — no end-of-life risk for new designs The CY8C4247AZI-L475 carries an Active product status with ROHS3 compliance. There is no last-time-buy notice or obsolescence risk for current production.","metaTitle":"CY8C4247AZI-L475 PSoC 4 MCU, 48 MHz ARM Cortex-M0","metaDescription":"Infineon PSoC 4 CY8C4247AZI-L475 32-bit MCU with ARM Cortex-M0 at 48 MHz, 128 KB Flash, 16 KB SRAM, CapSense, industrial temp -40°C to 85°C, 64-TQFP.","metaKeywords":null},"attributes":{"series":"PSOC® 4 CY8C42xx-L","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Speed":"48MHz","Series":"PSOC® 4 CY8C42xx-L","Package":"Tray","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, Cap Sense, DMA, LVD, POR, PWM, SmartSense, WDT","Connectivity":"I²C, IrDA, LINbus, Microwire, SmartCard, SPI, SSP, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"53","Core Processor":"ARM® Cortex®-M0","Package / Case":"64-LQFP","Data Converters":"A/D 16x12b SAR; D/A 4x8b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"64-TQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.44","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.44000","currency":"USD"},{"qty":10,"price":"$10.33600","currency":"USD"},{"qty":25,"price":"$9.85560","currency":"USD"},{"qty":160,"price":"$8.55750","currency":"USD"},{"qty":320,"price":"$8.17291","currency":"USD"},{"qty":480,"price":"$7.45177","currency":"USD"},{"qty":960,"price":"$6.49026","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ef317ed61d912817a01494e3770a0c6e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does CY8C4247AZI-L475 support capacitive touch touchscreens?","answer":"Yes. The CY8C4247AZI-L475 integrates CapSense and SmartSense peripherals for capacitive touch sensing. It supports self-capacitance and mutual-capacitance touch interfaces, including touchscreens and touchpad arrays, without requiring an external touch controller IC."},{"question":"What programmer/debugger is required for CY8C4247AZI-L475?","answer":"The CY8C4247AZI-L475 uses the standard ARM Serial Wire Debug (SWD) interface. Infineon's PSoC Programmer software and hardware tools like the PSoC 4 Pioneer Kit or a third-party SWD debugger (e.g., Segger J-Link) work. The SWD pins are multiplexed with GPIO, so the debug interface stays available even with the watchdog enabled."},{"question":"What is the closest functional alternative to CY8C4247AZI-L475?","answer":"Within the PSoC 4 family, the CY8C4247LQI-BL473 is a pin-compatible alternative in a smaller 68-pin QFN package with 36 I/O and 8-channel ADC, plus integrated Bluetooth LE. The CY8C4245LQI-483 offers a lower-density option with 34 I/O and 2-channel IDAC. Both run the same 48 MHz Cortex-M0 core and share the CapSense peripheral, but differ in I/O count, ADC channels, and package footprint. For a direct drop-in replacement, the CY8C4247AZI-L475 itself is the active primary part — no official second-source is listed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C4247AZI-L475","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C4247AZI-L475 when reusing this data.
