FEBL9800-03
MSM9800/9836 EVA Board
20-pin Connector
The connector provides an interface for an external MCU control.
You can input/output control signals via this 20-pin connector when you use an external MCU to control the
board. The following table describes the pin connections.

Note 1: 1-3 pins of this connector output +5 V. Short circuit with power supply circuit of the external
unit may cause damage of the power supply unit and/or the evaluation board. (The
connector’s 1 - 3 pins should be cut and isolated, as required.)
Note 2: Every input pin is either pulled-up or pulled-down with a resistor. Be aware that not every pin
function identically to those on your target device, MSM9802/03/05/36.
