Development Tools
All communication is done by means of LIN
frames or BiPhase-M telegrams depending
on the sensor type. For engineering pur-
poses, Micronas offers an easy-to-use
application kit:

HAL Programmer Board
System Architecture
The HAL 28xy sensors are produced in a
proven automotive submicron CMOS tech-
nology.
The HAL 28xy family features a tempera-
ture-compensated Hall plate with spinning-
current offset compensation, an A/D con-
verter for the Hall-plate, an A/D converter
for the temperature sensor, digital signal
processing (RISC processor), different fully
integrated digital interfaces including the
physical layer, an EEPROM memory with
redundancy and lock function for the cali-
bration data, and protection devices on all
pins.
The HAL 28xy family is programmable by
means of LIN frames or by a BiPhase-M
telegram. No additional programming pin is
needed.
