SE98A
DDR memory module temp sensor, 1.7 V to 3.6 V
9.   Application design-in information
In a typical application, the SE98A behaves as a slave device and interfaces to the master
(or host) via the SCL and SDA lines. The host monitors the EVENT
 output pin, which is
asserted when the temperature reading exceeds the programmed values in the alarm
registers. The A0, A1 and A2 pins are directly connected to the shared SPDs A0, A1 and
A2 pins, otherwise they must be pulled HIGH or LOW. The SDA and SCL serial interface
pins are open-drain and require pull-up resistors, and are able to sink a maximum current
of 3 mA with a voltage drop less than 0.4 V. Typical pull-up values for SCL and SDA are
10 k? but the resistor values can be changed in order to meet the rise time requirement if
the capacitance load is too large due to routing, connectors, or multiple components
sharing the same bus.
