Functional Description

JTAG

JTAG access to TEI0006 SoM is only through B2B connector J2 available. The JTAG signals are routed directly from B2B connector through Intel MAX 10 to Intel Cyclone 10 GX.

Access between Intel MAX 10 and Intel Cyclone 10 GX can be selected via the JTAGEN pin. The JTAGEN pin is already pulled up to 3.3V for access to Intel MAX 10. For access to Intel Cyclone 10 GX the JTAGEN pin has to pulled down to GND on B2B connector J2-105.

UART

UART signals are routed directly from B2B connector through Intel MAX 10 to Intel Cyclone 10 GX.

The following LEDs on the TEI0006 module can be controlled directly by the Cyclone 10 GX:

The signals for the Ethernet LEDs are routed through the MAX10 as follows:

PHY1_LED1

...

→ B2B connector J2-67 / PHY1_33LED1

...

PHY1_LED2

...

→ B2B connector J2-69 / PHY1_33LED2

...

Power

...

All power regulators are controlled by the power sequencer core. It enables and discharges the power regulators and monitors the power good signals.

The power-up sequence corresponds to Intel's recommendations and is shown in the table below:

The voltages for Bank 2K ( VCCIO2K) and Bank 2J (VCCIO2J) are supplied externally via the B2B connectors (J1-53/53 and J2-29/30).

Output voltage VADJ of power regulator U11 is set to 1.8V via VADJ_VS0

and VADJ_VS1 pin

...

. Possible selectable voltages are 1.8V, 2.5V and 3.0V.
