Wired interfaces include I²C, SPI, UART/USART, LIN, IrDA, and SmartCard — the part can bridge a BLE link to an industrial sensor bus or a legacy serial protocol. Surface-mount assembly; the tray packaging is standard for volume reflow.","metaTitle":"CY8C4247LQI-BL473 Infineon PSoC 4 BLE MCU, 48 MHz","metaDescription":"Infineon CY8C4247LQI-BL473 PSoC 4 BLE MCU: ARM Cortex-M0 at 48 MHz, 128 KB flash, 16 KB RAM, Bluetooth, 36 I/O, -40 to 85°C.
