6.2.2

Capability Register (16-bit Read-only, Address = 00h)

This register is a 16-bit read-only register used to specify the functional capabilities of the temperature sensor.

The AT30TS01 is capable of measuring temperature with ±1

C over the active range and ±2C over the monitor

range. The Capability Register functions are described in Table 6-3 and Table 6-4.

RFU

Reserved for Future Use. Read as Logic 0.

7

EVSD

Event Output Status During Shutdown Mode:

0 = The EVENT output freezes in its current state when entering shutdown. Upon exiting

shutdown, the EVENT output remains in theprevious state until the next thermal sample is

taken, or possibly sooner if EVENT pin is programmed for comparator mode.

6

TMOUT

Timeout:

1 = Bus Timeout supported within the range 25 to 35ms.

5

RFU

Reserved for Future Use. Read as Logic 1.

TPRES

Temperature Resolution:

11 = 0.0625C (12-bit) only.

2

RANGE

1 = Can read temperatures below 0°C and sets appropriate sign bit.

1

SACC

Supported Accuracy:

1 = Supports accuracy of ±1C over the active range (75C to 95C) and 2C over the (40C to

125

C) range.

0

ICAP

Interrupt Capability:

1 = Supports Interrupt capabilities.
