iC-TW28 identification data and serial number are also are available for user information (product ID, serial
stored in the EEPROM. Additionally, four bytes of data number, etc.) in the EEPROM.
ELECTRICAL CONNECTIONS
The basic electrical connections for a typical sin/cos sensor, only a few bypass capacitors and other
stand-alone application using the iC-TW28 in pin con- components are required for operation.
