MCP2221-I/P
接口桥接器, USB 至 I2C, SMBUS, UART, 3 V, 5.5 V, DIP, 14 引脚, -40 °C
产品概述
The MCP2221-I/P is an USB 2.0 to UART/I²C™ Protocol Converter with GPIO enables USB connectivity in applications that have an UART and I²C interfaces. The device reduces external components by integrating the USB termination resistors and the oscillator needed for USB operation. The MCP2221 also has four GP-pins providing miscellaneous functionalities (GPIO, USBCFG, SSPND, clock output, ADC, DAC, interrupt detector). The MCP2221 enumerates as a composite USB device after POR. The device enumerates as both a human interface device (HID) for I²C, GPIO control and as CDC for the USB-to-UART converter.
- Supports full-speed USB (12Mbps)
- Implements USB protocol composite device
- 128-byte buffer to handle data throughput at any UART baud rate
- Human interface device (HID) for both I²C™ communication and control
- USB 2.0 compliant
- Human interface device (HID) for both I²C™ communication and control
- I²C/SMBus terminal
- Communications device class (CDC) for the USB-to-UART option
- Device runs as an I²C master
- Data to write/read on the I²C bus is conveyed by the USB interface
- Four general-purpose input/output pins
- All GP pins can be assigned to other functionalities
- UART activity LED outputs (UTX and URX)
- SSPND output pin
- USBCFG output pin (indicates when the enumeration has completed)
- Three ADC inputs
- One DAC with two possible output options
- 12MHz or other configurable values clock reference output
- External interrupt edge detection
