0.5 ms Fast reset is triggered by
disabling startup BIST
(S_BIST = 0), then enabling
chip reset (AS_RST = 1)
1) Directly blocked with 100-nF ceramic capacitor
2) Values refer to a homogeneous magnetic field (B_XY) without vertical magnetic induction (B_Z = 0mT).
3) See Figure 4-1
4) During “Power-on time,” write access is not permitted (except for the switch to External Clock which requires a readout as
a confirmation that external clock is selected)
5) Not subject to production test - verified by design/characterization
The field strength of a magnet can be selected within the colored area of Figure 4-1. By limitation of the junction
temperature, a higher magnetic field can be applied. In case of a maximum temperature T_J = 100°C, a magnet
with up to 60mT at T_J = 25°C is allowed.
It is also possible to widen the magnetic field range for higher temperatures. In that case, additional angle errors
have to be considered.
