MCP2200 USB-to-UART serial converter

The MCP2200 is a USB-to-UART serial converter manufactured by Microchip and enables USB connectivity in applications that have a UART interface. The device reduces external components by integrating the USB termination resistors. The MCP2200 also has 256 bytes of integrated user EEPROM  that  is accessed for read/write operations via USB host commands.

The MCP2200 has eight general purpose input/output pins (four pins have alternate functions to indicate USB and communication status ) . In other words the MCP2200 is chip that make possible a data connection between a USB and a RS232 port .

The MCP2200 is a USB-to-UART serial converter operates from 3 to 5.5 input voltage range .

The MCP2200 has a RST (reset ) pin which provides a method for triggering an external Reset of the device. Also the chip has a POR pin ( Power-on Reset ) that allows the device to start in the initialized state when VDD is adequate for .

The MCP2200 is configured by writing special commands using the HID interface and can be achieved using the configuration utility provided by Microchip.

Main features of the MCP2200 USB-to-UART serial converter are : supports full-speed USB (12 Mb/s) , implements USB protocol composite device CDC device for communications, 128 byte buffer to handle data throughput at any UART baud rate( 64byte transmit ,  64 byte receive ) , bus powered or self-powered , USB 2.0 compliant  , uses standard Microsoft® Windows® drivers for Virtual Com Port (VCP)  , responds to SET LINE CODING commands to dynamically change baud rates , supports baud rates: 300-1000k , hardware flow control , 256 bytes of user EEPROM , USB activity LED outputs (TxLED and RxLED) ,  oscillator input: 12 MHz .
