• Manufacturer Part Number: ASC7531A
• Description: LOW-VOLTAGE 1-WIRE DIGITAL TEMPERATURE SENSOR AND VOLTAGE MONITOR
• Manufacturer: ETC2 [List of Unclassifed Manufacturers]

Device Interface Field (1-byte)
The vendor sets to ‘1’, bit positions in this field in the event the device supports higher layer protocols that are industry specific using
Table 5.
Value = 0x02
Function Interface Field (1-byte)
This field provides a mechanism for a device to pass higher-layer SST device-specific information.
Value = 0x00
Device Interface Extension Field (1-byte)
This field is used to provide additional information about the device to the upper layers of software.
Value = 0x00
Reserved Field (3-bytes)
Value = 0x00 0x00 0x00
Vendor Specific ID Field (1-byte)
This field is set by the vendor in a way that uniquely identifies this device apart from all others with an otherwise common DIB
content.
Value = 0x00 – For Fixed address devices this field may be set to zero.
Client Device Address (1-byte)
SST Client Device Address is set according to the connection of the ADD0 pin. The combination part appears to software as two
sensors, a simple temperature and a simple voltage sensor residing at the same address. Float is defined as an unconnected pin.
