What sets this part apart is the integrated Bluetooth radio and CapSense touch-sensing hardware — it's designed for wireless sensor nodes, human-machine interfaces, and battery-operated products where board space is tight. Supply voltage is 1.71 V. No need to stockpile or hunt for obsolete inventory. ## 68-WLCSP footprint — what it means for assembly The package is bare silicon with solder bumps — no plastic overmold — so it's more sensitive to moisture and mechanical stress. Surface-mount assembly with a fine-pitch WLCSP requires a solder paste stencil designed for the ball diameter and pitch, plus a reflow profile that matches the package's thermal mass. X-ray inspection after reflow is standard practice to catch head-in-pillow or non-wet opens. ## Peripheral set — Bluetooth, CapSense, and more Beyond the BLE radio, the peripheral list includes CapSense (for touch buttons and sliders), a brown-out detect/reset, low-voltage detect, power-on reset, PWM, and a watchdog timer. The connectivity block supports I²C, IrDA, LINbus, Microwire, SmartCard, SPI, SSP, and UART/USART — enough to talk to most sensors, displays, and serial peripherals without external protocol translators. The 8-channel 12-bit successive-approximation ADC is the primary analog front-end. No DAC is listed on this variant, so if you need analog output, you'll route PWM through an external filter or step up to a sibling with integrated IDAC.","metaTitle":"CY8C4247FNI-BL493T PSoC 4 BLE MCU, ARM Cortex-M0, 48 MHz","metaDescription":"Infineon CY8C4247FNI-BL493T PSoC 4 BLE MCU: ARM Cortex-M0 32-bit at 48 MHz, 128 KB Flash, 36 I/O, 8x12b ADC, Bluetooth, CapSense, -40°C to 85°C, 68-WLCSP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"series":"PSOC® 4 CY8C4xx8 BLE","has_mpn":"CY8C4247","cpu_core":"ARM® Cortex®-M0","frame_size":"32-Bit Single-Core","fuse_speed":"48 MHz","connectivity":"I²C, IrDA, LINbus, Microwire, SmartCard, SPI, SSP, UART/USART","package_type":"Bulk","Number Of I/O":"36","mounting_type":"Surface Mount","product_status":"Active","Data Converters":"A/D 8x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","peripheral_types":"Bluetooth, Brown-out Detect/Reset, Cap Sense, LCD, LVD, POR, PWM, SmartCard, SmartSense, WDT","supply_voltage_v":"1.71","Program Memory Type":"FLASH","Operating Temperature High":"-40°C to 85°C (TA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.23","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e436643f32b236adb34e62a6be5a0038.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY8C4247FNI-BL493T/alternatives.json"},"ai":{"faq":[{"question":"Are there alternative parts to CY8C4247FNI-BL493T?","answer":"The closest functional peer is the CY8C4247LQI-BL473, which shares the same PSoC 4 BLE series, Cortex-M0 core, 48 MHz clock, 36 I/O, and 8x12b ADC. The main difference is the package — the LQI variant comes in a QFN tray package instead of the WLCSP, which changes the footprint and reflow profile.
