MCP2210T-I/SS

Controllers Overview

The MCP2210T-I/SS is a USB-to-SPI protocol converter manufactured by Microchip Technology, designed for host-mode connectivity. It integrates a full-speed USB 2.0 controller and an SPI master peripheral within a 20-lead SSOP package. The device supports data rates up to 12 Mbps and operates on a single power supply ranging from 3.3 V to 5.5 V. It features nine general-purpose I/O pins, including eight configurable I/Os and one dedicated input, alongside 256 bytes of user-accessible EEPROM. The component functions as a Human Interface Device (HID), eliminating the need for custom drivers on supported operating systems.

Controllers Feature Summary

• Integrates USB 2.0 full-speed compliance with HID class support for driverless operation on standard operating systems.
• Provides configurable SPI master functionality supporting all four modes with adjustable bit rates and transaction delays.
• Includes nine general-purpose I/O pins that can be assigned as GPIO, Chip Select lines, or dedicated status indicators.

Controllers Applications

• Adding USB connectivity to existing SPI-based embedded systems
• Data collection and transfer applications requiring protocol conversion
• Industrial control interfaces utilizing SPI peripherals

Controllers Procurement Notes

Verify the specific ordering suffix 'I/SS' corresponds to the industrial temperature range and SSOP-20 package type required for your design. Confirm that the source document explicitly links this suffix to these specifications before finalizing procurement decisions. Ensure compatibility with the intended power supply configuration, as the device supports both bus-powered and self-powered modes depending on VDD and VUSB connections.

Controllers Selection Notes

Select this component when a compact solution is needed to bridge USB hosts to SPI slaves without external protocol controllers. Consider the 20-lead SSOP package constraints regarding board space and thermal performance. Evaluate the available GPIO count against the requirement for Chip Select lines and status signals. Verify that the 128-byte buffer size meets the throughput requirements for the specific SPI transactions planned.

Controllers Part Context

The MCP2210 series includes variants in QFN and SOIC packages. The 'T' designation typically indicates tape and reel packaging, while 'I' denotes the industrial temperature grade. The 'SS' suffix specifically identifies the SSOP-20 physical package. Other family members may offer different pin counts or package styles but share the core USB-to-SPI functionality.

Controllers Replacement Considerations

Direct replacements must maintain USB HID compatibility and SPI master capabilities. Check datasheets for equivalent pinouts and electrical characteristics. Verify that alternative components support the same voltage ranges and GPIO configurations to ensure mechanical and functional interchangeability without redesigning the PCB layout.
