MCP2210-I/MQ

Controllers Overview

The MCP2210-I/MQ is a USB-to-SPI protocol converter manufactured by Microchip Technology, designed to add USB connectivity to SPI-based systems. 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 features an integrated SPI host peripheral supporting all four modes with bit rates from 1500 bps up to 12 Mbps. It includes nine General Purpose Input/Output (GPIO) pins, which can be configured as digital I/O, Chip Select lines, or dedicated status indicators. The component operates within a voltage range of 3.3V to 5.5V and is housed in a 20-lead QFN package measuring 5 x 5 mm.

Controllers Feature Summary

• Integrates USB 2.0 full-speed controller and SPI master peripheral into a single chip
• Enumerates as a standard HID device for driver-free operation across major operating systems
• Provides configurable GPIO pins with alternate functions for status signaling and bus control
• Includes 256 bytes of user-accessible EEPROM for non-volatile configuration storage

Controllers Applications

• Adding USB-certified connectivity to existing SPI-based embedded systems
• Data collection, transfer, and analysis interfaces for industrial equipment
• Development tools and adapters for programming SPI flash memory devices
• Prototyping platforms requiring flexible USB-to-digital interface conversion

Controllers Procurement Notes

Verify the specific suffix 'MQ' corresponds to the 20-lead QFN package variant when sourcing. Confirm that the industrial temperature grade (-40°C to +85°C) meets your environmental requirements. Ensure that the USB HID class support aligns with your target operating system constraints. Check for any specific factory programming needs regarding VID/PID assignments if standard defaults are insufficient.

Controllers Selection Notes

Select this component when a compact solution is required to bridge USB hosts to SPI slaves without complex firmware development. Consider the 128-byte buffer size for throughput requirements, noting it supports 64-byte transmit and receive operations. Evaluate the GPIO flexibility if multiple Chip Select lines or status LEDs are needed. Ensure the 12 MHz oscillator requirement can be met with external components like quartz crystals or ceramic resonators.

Controllers Part Context

The MCP2210 belongs to Microchip's family of USB-to-serial and protocol converters. Unlike the MCP2221 which focuses on I2C and UART, the MCP2210 is specialized for SPI communication. It shares similar HID enumeration characteristics with other Microchip USB controllers but offers distinct SPI timing controls and GPIO configurations tailored for serial peripheral interface applications.

Controllers Replacement Considerations

Direct replacements include other MCP2210 variants such as MCP2210-I/SS or MCP2210-I/SO, differing primarily in package type (SSOP or SOIC) rather than functionality. No alternative functional substitutes exist within the provided data; cross-family parts like MCP2221 serve different protocols (I2C/UART) and are not electrically compatible.
