Development Tools

As all communication is done by means of

LIN frames, any available LIN tool chain

can be used for configuration and program-

ming of the HAL 28xy.

For engineering purposes, Micronas offers

an easy-to-use application kit:

System Architecture

The HAL 2810 sensors are produced in a

proven automotive submicron CMOS tech-

nology.

The HAL 2810 features a temperature-com-

pensated Hall plate with spinning-current

offset compensation, an A/D converter for

the Hall-plate, an A/D converter for the tem-

perature sensor, digital signal processing, a

fully integrated LIN interface including the

physical layer, an EEPROM memory with

redundancy and lock function for the cali-

bration data and the LIN configuration, and

protection devices on all pins.

The HAL 2810 is programmable by means

of LIN frames. No additional programming

pin is needed.
