MCP2221A中文资料USB 2.0 to I^2C/UART Protocol Converter with GPIO数据手册Microchip规格书

描述 Description

The MCP2221A is a USB-to-UART/I²C serial converter which enables USB connectivity in applications that have a UART and I²C interfaces. The device reduces external components by integrating the USB termination resistors and the oscillator needed for USB operation. The MCP2221A also has four GP pins providing miscellaneous functionalities (GPIO, USBCFG, SSPND, Clock Output, ADC, DAC, interrupt detector).The MCP2221A is identical to the MCP2221 in all aspects except for the maximum supported baud rate of the UART, which has been increased from 115200 (MCP2221) to 460800 (MCP2221A). All MCP2221 USB Drivers and Software can be used for the MCP2221A.

特性 Features

• Supports full-speed USB (12 Mb/s)
