CEC Pins
50 CEC_A I/O
HDMI compliant CEC I/O used for interfacing to CEC devices. The signal is electrically compliant with CEC
specification. This pin connects to the CEC signal of all HDMI connectors in the system. As an input, the pin
acts as a LVTTL, Schmitt triggered input and is 5V tolerant. As an output, the pin acts as an NMOS driver
with resistive pull-up. This pin has an internal pull-up resistor.
51 CEC_D I/O
CEC interface to local system.
This pin is an open drain and requires an external pull-up resister. This pin typically connects to a local CPU
if the CEC functions are performed by the CPU directly, and not the CEC controller inside the device.
Power and Ground Pins
9,27,64 VCC33 - Analog and digital core VCC. Must be supplied at 3.3V
37 MICOM_VCC33 -
During normal mode, this pin provides 3.3V power to external micro-controller. Maximum output current is
30mA. This pin requires 1µ F capacitor to ground.
38 SBVCC33 - 3.3V standby power. If 3.3V standby mode is not used, this pin should be left as not connected.
ePad Epad -
ePad must be connected to ground. All ground planes, analog and digital, must be tied together to the ePad,
which must be connected to ground.
