MCP2200T-E/SS

Controllers Overview

The MCP2200T-E/SS is a USB-to-UART serial converter manufactured by Microchip Technology, housed in a 20-lead SSOP package. It supports Full-Speed USB (12 Mb/s) and implements a composite device protocol using Communication Device Class (CDC) for data translation and Human Interface Device (HID) for configuration and I/O control. The device features an integrated 128-byte buffer (64-byte transmit, 64-byte receive), eight configurable General Purpose Input/Output (GPIO) pins, and 256 bytes of user-accessible EEPROM. Operating voltage ranges from 3.0V to 5.5V with a typical supply current of 13mA. It supports baud rates from 300 bps to 1000 kbps and includes hardware flow control via RTS and CTS pins.

Controllers Feature Summary

• Integrates USB 2.0 full-speed transceiver with internal pull-up resistors and a 3.3V LDO for the USB interface.
• Provides eight GPIO pins with configurable functions including USB activity LED outputs, suspend status, and configuration status.
• Includes 256 bytes of non-volatile EEPROM for storing custom VID/PID assignments, string descriptors, and UART default settings.
• Supports dynamic baud rate changes via SET_LINE_CODING commands and offers hardware flow control through dedicated RTS and CTS pins.

Controllers Applications

• Converting USB connectivity to UART interfaces in embedded systems requiring virtual COM port functionality.
• Industrial applications needing robust GPIO control alongside serial communication over USB.
• Prototyping and development environments utilizing standard Windows drivers for rapid UART integration.

Controllers Procurement Notes

Verify the 'E' suffix indicates the extended temperature range variant if specified in official Microchip documentation, as standard datasheets typically list the 'I' suffix for industrial range (-40°C to +85°C). Confirm package availability in 20-SSOP format. Ensure ordering specifications match the exact electrical characteristics required for the target application environment.

Controllers Selection Notes

Select this component when a USB-to-UART bridge with integrated GPIO and EEPROM is required. It is suitable for designs needing bus-powered or self-powered operation with flexible logic levels determined by the VDD supply. Consider the 20-SSOP package for surface-mount assembly requirements. Verify compatibility with the target operating system's driver support for HID and CDC classes.

Controllers Part Context

The MCP2200 series serves as a low-cost alternative to traditional USB-to-serial converters by eliminating external components through integrated termination resistors and oscillators. The 'T' designation typically indicates tape and reel packaging, while 'SS' denotes the 20-lead Shrink Small Outline Package. This specific part number represents a variant within the broader MCP2200 family designed for versatile serial communication needs.

Controllers Replacement Considerations

Direct pin-compatible replacements include other MCP2200 variants such as MCP2200-I/SS or MCP2200T-I/SO, provided the temperature rating meets application requirements. Cross-brand alternatives like FTDI chips may require schematic and software modifications due to differing pinouts and driver architectures.
