12 Atmel AT30TS00 [Preliminary]

8585B−SEEPR−8/10

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

The Atmel

AT30TS00 is capable of measuring temperature with ±1°C over the active range and ±2°C over the

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

sensor. The capability register functions are described in Table 6-3 and Table 6-4.

Table 6-4. Capability Register Bit Description

Bit Symbol Description

15:8 RFU Reserved for Future Use and must be '0'

7 EVSD

1 = The

EVENT

pin is deasserted (not driven) when entering shutdown mode, and upon

existing shutdown mode, the

EVENT

pin goes back to previous state it was in prior to

shutdown mode and will be updated after one thermal conversion cycle

6 TMOUT

1 = Parameter

OUT

is supported within the range of 25 to 35mS (SMBus compatible)

Please note the SMBus Timeout feature is supported in shutdown mode and will consume

more current if Timeout is engaged but not timed out (see Icc parameter in DC

Characteristics)

5 RFU Reserved for Future Use and must be '0'

4:3 TPRES Temperature resolution

'10' – supports 0.125°C

2 RANGE '1' – Can read temperatures below 0°C and sets appropriate sign bit

1 SACC Supported Accuracy. '1' – Supports B grade accuracy of ± 1°C over the active

range (75°C to 95°C ) and 2°C over the monitor range (40°C to 125°C )

0 ICAP Interrupt Capability. '1' – has alarm and critical trip interrupt capability
