DS20005426G-page 41 MCP960X/L0X/RL0X 5.3.4 DEVICE ID AND REVISION ID REGISTER The Device ID (Identification) and Revision ID register is a 16-bit read-only register, which can be used to identify this device among other devices on the I2C bus. The upper 8 bits indicate the Device ID of 0x40 for the MCP9600/L00/RL00 and 0x41 for the MCP9601/L01/RL01 respectively, while the lower 8 bits indicate the device revision. The device revision byte is divided into nibbles, where the upper nibble indicates the major revision and the lower nibble indicates minor revisions. The initial release is indicated by a major revision of ‘1’ and a minor revision of ‘0’ or 0x4010 for the MCP9600/L00/RL00 and 0x4110 for the MCP9601/L01/RL01. (Refer to “MCP9600 Silicon Errata and Data Sheet Clarification”, DS80000741, for changes and revision IDs).
