The TMP512/13 uses a bank of registers for holding

the write command. Therefore, a 4

μs delay is

configuration

settings,

measurement

results,

required between the completion of a write to a given

maximum/minimum limits, and status information.

registers.

(without changing the pointer) when using SCL

μs after completion of

frequencies in excess of 1MHz.

R/W

(1)

Type: R = Read-Only, R/W = Read/Write.

(2)

Current Register defaults to

'0' because the Calibration Register defaults to '0', yielding a zero current value until the Calibration Register

is programmed.

(3)

For TMP513 only.
