In these two equations, TEMPCALH and TEMPCALL are a pair of Flash option bits con-
taining the calibration data. For more details, see the discussion of TEMPCALH and
TEMPCALL in the Flash Option Bits chapter on page 276.
Note: The equations above are temporary test results of the Z8F1680 MCU, version A. The coef-
ficient in the formula may change according to results from tests of version B.
19.1.1. Calibration
The temperature sensor undergoes calibration during the manufacturing process and is
maximally accurate only at 30° C. Accuracy decreases as measured temperatures move
further from the calibration point.
Because this sensor is an on-chip sensor, Zilog recommends that the user accounts for the
difference between ambient and die temperatures when inferring ambient temperature
conditions.
