Programmable Sensor Interface  
Unique Features  
Customization  
Table 2. Absolute Maximum Ratings  
Melexis can customize the MLX90314 in both  
hardware and firmware for unique requirements. The  
hardware design provides 64 bytes of RAM, 3 kbytes  
of ROM, and 48 bytes of EEPROM for use by the  
firmware.

Special Information  
The output of the sensor bridge is amplified via offset  
and gain amplifiers and then converted to the correct  
output signal form in one of the output stages.

Output current, IVMO  
The sensitivity and offset of the analog signal chain  
are defined by numbers passed to the DAC interfaces  
from the microcontroller core (GN[9:0] and OF[9:0]).  
The wide range of bridge offset and gain is  
accommodated by means of a 2-bit coarse adjustment  
DAC in the offset adjustment (CSOF[1:0]), and a  
similar one in the gain adjustment (CSGN[2:0]). The  
signal path can be directed through the processor for  
digital processing. Two I/O pins are available for  
analog inputs or digital outputs. These pins can be  
used for alarms on various points on the analog signal  
path and built-in or external temperature values.

Programming and Setup  
The MLX90314 needs to have the compensation  
coefficients programmed for a particular bridge  
sensor to create the sensor system.  
Programming the EEPROM involves some  
minimal communications interface circuitry,  
Melexis’ setup software, and  
communications interface circuitry is available in  
development board. This circuitry  
a
PC. The  
a
communicates with the PC via a standard RS-  
232 serial communications port.  
Cross Reference  
There are no known devices which the MLX 90314  
can replace.  
ESD Precautions  
Observe standard ESD control procedures for CMOS  
semiconductors.
