DEVICE ID AND REVISION

The Device ID and Revision register located at address

pointer 0x08 is used to identify Microchip devices. The

upper byte of these registers is used to specify the

device identification and the lower byte is used to

specify device silicon revision. The device ID for the

MCP9844 is 0x06 (hex) and the silicon revision is 0x00.

The revision (Lower Byte) begins with 0x00 (hex) for

the first release, with the number being incremented as

revised versions are released.
