This part is designed for wireless sensor nodes, human-machine interfaces, portable medical devices, and industrial controls where a single-chip BLE solution with analog front-end and touch sensing replaces a multi-IC BOM. The 48 MHz Cortex-M0 core is a balanced trade-off: enough throughput for BLE protocol stacks, sensor polling loops, and capacitive touch scanning without the power overhead of a Cortex-M4. The 8 KB SRAM (implied by the PSoC 4 BLE family architecture) handles BLE connection buffers and a modest RTOS tick. If your application needs a larger code footprint or a DSP-capable core, the PSoC 6 series (CY8C6137BZI-F54) with Cortex-M4 at 150 MHz is a pin-incompatible but architecturally related step-up. ## Bluetooth, CapSense, and LCD drive — peripherals that define the part The CY8C4247LQI-BL493 includes Bluetooth LE (BLE) radio, CapSense capacitive touch sensing, and LCD segment drive as on-chip peripherals. The BLE block is Bluetooth 4.2 compliant — it does not support Bluetooth 5.0 features like LE Audio, 2 Mbps PHY, or extended advertising. If your product requires Bluetooth 5.0, a newer PSoC 6 BLE variant or an external BLE 5.0 transceiver would be needed. The CapSense block supports self-capacitance and mutual-capacitance sensing for touch buttons, sliders, and proximity detection without external touch controller ICs. The LCD drive supports up to 32x4 segment displays, useful for battery-powered instruments with a simple glass LCD. The supply voltage range of 1.71 V to (implied 3.6 V by the PSoC 4 family) allows direct battery operation from a single Li-ion cell or two alkaline cells without a separate regulator.","metaTitle":"CY8C4247LQI-BL493 PSoC 4 BLE MCU, ARM Cortex-M0, 48 MHz","metaDescription":"Infineon CY8C4247LQI-BL493 is a 32-bit ARM Cortex-M0 MCU from the PSoC 4 BLE series, 48 MHz, 128 KB Flash, 56-QFN, -40 to 85°C.","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":"$5.09","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e436643f32b236adb34e62a6be5a0038.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY8C4247LQI-BL493/alternatives.json"},"ai":{"faq":[{"question":"Does CY8C4247LQI-BL493 support Bluetooth 5.0?","answer":"No, the integrated BLE radio is Bluetooth 4.2 compliant.
