Description

Number

1

CS

Chip Select input

This pin receives an active-low signal from the controller to select the device.

2

GND

Ground

This is the power and signal ground return.

3

SI/O

Serial Input/Output

This serial, bidirectional, data bus pin transmits and receives signals to and from the

controller. Schmitt trigger input in the input mode.

4

SC

Serial bus clock

This serial clock signal comes from the controller. Schmitt trigger input.

5

Positive Supply Voltage

Supply a DC voltage from 2.4V to 5.5V to this pin and bypass with a 0.1 µF ceramic

capacitor to ground.

Typical Application

Figure 1. COP Microcontroller Interface

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

Soldering process must comply with Reflow Temperature Profile specifications.

(1)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not

apply when operating the device beyond its rated operating conditions.

(2)

5 mA.

(3)

Human body model, 100 pF discharged through a 1.5 k

Ω resistor. Machine model, 200 pF discharged directly into each pin.

(4)

Reflow temperature profiles are different for lead-free and non-lead-free packages.
