MCP2221 I2C SMBus Terminal 2.0

MCP2221 I2C SMBus Terminal is a desktop utility from Microchip Technology Inc. that lets you communicate with I2C and SMBus peripherals through the MCP2221/MCP2221A USB-to-I2C bridge—no firmware or host code required. It provides an intuitive interface for discovering devices on the bus, issuing read/write transactions, and exercising standard SMBus commands during prototyping, bring-up, and test.

Key features:

• Simple USB connection to MCP2221/MCP2221A devices
• I2C clock selection for Standard and Fast modes
• Address scanning and device discovery
• Single and repeated-start transactions (byte, word, and block transfers)

• Transaction scripting and batch execution with save/load support
• Live logs with timestamps, ACK/NACK status, and error reporting
• Session export for documentation and analysis

Ideal for quickly evaluating sensors, EEPROMs, power monitors, and other I2C/SMBus devices, this tool streamlines development and validation by turning your MCP2221/MCP2221A into a flexible, PC-controlled bus master.
