MCP2210T-I/MQ

Controllers Overview

The MCP2210T-I/MQ is a USB-to-SPI protocol converter manufactured by Microchip Technology, designed for industrial applications with an operating temperature range of -40°C to +85°C. It supports Full-Speed USB (12 Mb/s) and enumerates as a Human Interface Device (HID), eliminating the need for custom drivers on Windows, Linux, and Mac OS. The device integrates a SPI host peripheral supporting all four modes with configurable bit rates from 1500 bps up to 12 Mbps. It features nine General Purpose Input/Output (GPIO) pins, including one input-only pin, and includes 256 bytes of user-accessible EEPROM. The component operates within a voltage range of 3.3V to 5.5V and utilizes a 12 MHz oscillator input.

Controllers Feature Summary

• Integrates USB 2.0 full-speed controller with HID class support for plug-and-play connectivity without custom drivers.
• Provides a flexible SPI host interface with configurable delays, multiple chip select lines, and support for all four SPI modes.
• Includes nine general-purpose I/O pins that can be individually configured as GPIO, chip selects, or dedicated status indicators.
• Features integrated 256-byte non-volatile memory for storing user data and persistent configuration settings.

Controllers Applications

• Adding USB connectivity to existing SPI-based embedded systems for data collection and analysis.
• Industrial automation interfaces requiring reliable SPI communication with sensors and actuators.
• Development and debugging tools for SPI peripherals in automotive and consumer electronics.
• Systems requiring flexible GPIO management alongside standard SPI transactions.

Controllers Procurement Notes

Verify the specific suffix 'I/MQ' corresponds to the industrial temperature grade and QFN package type before ordering. Confirm that the required firmware or configuration utility is available from the manufacturer's official resources. Ensure that the host system supports HID class devices if driverless operation is intended. Check for any recent product change notifications regarding pinout or electrical characteristics updates.

Controllers Selection Notes

Select this component when a robust, driverless USB-to-SPI bridge is required for industrial environments. Consider the MCP2210 over UART converters if precise SPI timing, multiple chip selects, or direct GPIO control is necessary. Evaluate the power supply requirements carefully, as the device supports both bus-powered and self-powered configurations depending on the VDD and VUSB connections. Ensure the application does not require high-speed USB transfers beyond the full-speed limit.

Controllers Part Context

The MCP2210 belongs to Microchip's family of USB interface integrated circuits designed to simplify connectivity. It serves as a bridge between USB hosts and SPI slave devices, reducing external component count by integrating termination resistors and oscillators. This series is distinct from UART or I2C bridges, focusing specifically on the SPI protocol with enhanced GPIO flexibility for complex system integration.

Controllers Replacement Considerations

Direct replacements must maintain USB HID compatibility and SPI master functionality. Verify that alternative components support the same industrial temperature range and package dimensions if board space is constrained. Ensure that the substitute device offers comparable GPIO configurability and EEPROM capacity for migrating existing configurations.
