MCP2200-I/SS

Controllers Overview

The MCP2200-I/SS 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 supply 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 includes eight general-purpose I/O pins, hardware flow control via RTS/CTS, and supports baud rates from 300 to 1000k. Operating temperature ranges from -40°C to +85°C. The component is housed in a 20-lead SSOP package.

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 an internal Low Dropout (LDO) regulator to power the USB transceiver, reducing external component count while supporting both bus-powered and self-powered configurations.
• Provides configurable general-purpose input/output pins that can function as standard I/O or indicate specific USB states such as suspend status, configuration completion, and traffic activity.

Controllers Applications

• Enabling USB connectivity for legacy applications requiring a UART interface without direct USB communication.
• Converting USB ports to virtual COM ports for computer-based serial data exchange.
• Industrial automation systems requiring robust serial communication with GPIO control capabilities.

Controllers Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the industrial grade variant (-I) meets the operational environmental requirements. Ensure compatibility with the intended host operating system drivers before finalizing procurement decisions.

Controllers Selection Notes

Select this component when a USB-to-UART bridge with integrated GPIO and EEPROM storage is required. Consider the 20-SSOP package for surface-mount assembly needs. Evaluate power options between bus-powered and self-powered modes based on system design constraints and current consumption limits.

Controllers Part Context

This part belongs to the MCP2200 series of USB-to-UART converters. It shares core functionality with other variants like the MCP2200T-I/SS and MCP2200-I/SO, differing primarily in packaging and tape-and-reel availability. The series is designed for low-cost USB integration in embedded systems.

Controllers Replacement Considerations

Direct substitutes include MCP2200T-I/SS and MCP2200-I/SO. Verify pinout compatibility and package dimensions before substitution. Ensure software drivers and configuration utilities remain compatible with the replacement part number.
