I'm trying to confirm compatibility between the LM80 and the LM96080.
Though the demo board helped clarify some doubts concerning ValueRam width, there is no direct access
to experiment with basic read/write functions. The only thing I had left to try is the iCHX Interface option (when loading the device),
but I haven't found much info on what that is, or if that is the approach to take at all..?
SensorEval software provides a very high level approach at experimenting with the basic read and write instructions. To be more specific, the data sheet
doesn't state the width for temperature or analog watchdog voltages (addresses 0h2A to 0h3B) ; I would assume the width is 10 bits like all analog input voltages in the same block , but I NEED to make SURE. To make things more confusing, SensorEval shows these values as being 8 bits? why!? Also, how many bits are considered in the comparison to set if a maximum has been violated?
Thanks in advance,
Gabriel
Hi Gabriel,
The width for the analog input voltages (register address 0x20-0x27) is indeed 10-bit (as shown in the SensorEval figure below), and the width for the temperature reading (register address 0x27) is 8-bit.
However, the input high and low limits (register address 0x2A to 0x37) is only 8-bit because we only allow you to compare the input voltage to a maximum of 2.55V.
I hope that helps.
