Programming of the EEPROM memory and
calculation of the individual sensor charac-
teristics can easily be done with a PC and
the application kit from Micronas:

System Architecture
The HAL 880 sensors are produced in a
proven submicron CMOS technology.
The HAL 880 features a temperature-com-
pensated Hall plate with choppered offset
compensation, an A/D converter, digital sig-
nal processing, a push-pull output, an
EEPROM memory with redundancy and
lock function for the calibration data and the
data register information, a serial interface
for programming the EEPROM, and protec-
tion devices on all pins.
The HAL 880 is programmable by modulat-
ing the supply voltage. No additional pro-
gramming pin is needed.
The internal digital signal processing is of
great benefit because analog offsets, tem-
perature shifts, and mechanical stress do
not degrade the sensor accuracy.
