MCP2200T-E/MQVAO

Controllers Overview

The MCP2200T-E/MQVAO is a USB-to-UART protocol converter with GPIO capabilities, manufactured by Microchip Technology. It supports Full-Speed USB (12 Mb/s) compliant with USB 2.0 standards and operates within a voltage range of 3.0V to 5.5V. The device features an integrated 128-byte buffer (64-byte transmit, 64-byte receive) and 256 bytes of user EEPROM. It provides eight general-purpose I/O pins and supports baud rates from 300 bps to 1000 kbps. Designed for industrial applications, it functions reliably between -40°C and +85°C.

Controllers Feature Summary

• Implements a composite USB device architecture utilizing Communication Device Class (CDC) for data translation and Human Interface Device (HID) for configuration and I/O control.
• Integrates hardware flow control via RTS and CTS pins to manage data throughput effectively at various UART baud rates.
• Includes configurable general-purpose input/output pins that can serve as status indicators for USB activity, suspend states, or configuration completion.

Controllers Applications

• Enabling USB connectivity in legacy embedded systems requiring a virtual COM port interface.
• Industrial automation setups needing robust serial communication with GPIO expansion capabilities.
• Prototyping environments where flexible USB-to-serial conversion with external pin control is required.

Controllers Procurement Notes

Verify the specific suffix MQVAO against official Microchip documentation to confirm package type and temperature grade alignment. Ensure compatibility with Windows operating systems ranging from XP SP2 through Windows 10 for driver support. Confirm that the industrial temperature rating meets your environmental requirements before finalizing procurement.

Controllers Selection Notes

Select this component when a USB-to-UART bridge with integrated GPIO is necessary without external transceivers. Consider the 12 MHz oscillator requirement and the need for local bypass capacitors on the VUSB pin. Evaluate if the 256-byte EEPROM suffices for storing custom VID/PID descriptors and initial configuration parameters.

Controllers Part Context

This part belongs to the MCP2200 family of USB-to-UART converters. It shares core functionality with variants like the MCP2200T-I/SO but differs in packaging and potentially automotive qualification status. The 'E' suffix typically denotes extended temperature ranges or specific reliability grades depending on the manufacturer's coding scheme.

Controllers Replacement Considerations

Direct substitutes include other MCP2200 variants such as MCP2200T-I/SO or MCP2200T-I/SSOP, provided the package footprint matches. Verify that alternative components maintain the same USB composite device class implementation and GPIO pinout compatibility.
