AT30TS01 [DATASHEET]

Atmel-8952A-DTS-AT30TS01-Datasheet_122015

6.2.9

Device ID Register (16-bit Read-only, Address = 07h)

The upper or high order byte is used to specify the device identification, and the low byte is used to specify the

device revision. The Device ID for the AT30TS01 is 3200h (see Table 6-18).

Temperature Sensor Write Operations

Writing to the AT30TS01 Temperature Register is accomplished through a modified write operation for two data

bytes. To maintain 2-wire compatibility, the 16-bit registers are accessed through a Pointer Register requiring

the TS write sequence to include a Pointer Register byte following the device address byte to write the two data

bytes. Figure 6-2 illustrates the entire write transaction.
