Notes: All the communication and refresh rate timings are given for the nominal calibrated HFO frequency and will vary
with this frequency’s variations.
*SMBus compatible interface is described in details in the SMBus detailed description section. Maximum number of
MLX90615 devices on one bus is 127, higher pullup currents are recommended for higher number of devices, faster bus
data transfer rates, and increased reactive loading of the bus.
MLX90615 is always a slave device on the bus. MLX90615 can work in both low-power and high-power SMBus
communication.
All voltages are with respect to the Vss (ground) unless otherwise noted.
