260-pin Connector

Overview​

Core 3588E connects to its carrier board through a 260-pin SO-DIMM edge connector with the pin assignment of the Jetson TX2 NX. This page is for carrier board design and for tracing a signal from a carrier board connector back to the module.

  • For the differences from the Jetson TX2 NX and the Jetson Orin Nano pin by pin, see the pin comparison (PDF).
  • This page describes the hardware. For which interfaces Mixtile OS sets up, and their device names, see Interfaces in Mixtile OS.

Electrical Notes​

  • The module needs only 5 V on VDD_IN. It generates all other voltages itself, and the carrier board does not supply any I/O voltage.
  • The I/O voltage of each signal is in the Type column of the tables below. Most GPIO, UART, SPI and I²S signals are 1.8 V at the connector. Carrier boards made for the Jetson TX2 NX translate them to the voltage of their headers.
  • An asterisk (*) marks an active-low signal.

PCIe​

PCIe 3.0, up to four lanes. Lanes 2 and 3, on pins 148 to 157, are reserved pins on the Jetson TX2 NX, so a carrier board designed only for the TX2 NX may connect two lanes.

Ground​

The 67 GND pins are listed in Pin Assignment. They are the ground return for power and for the high-speed signals next to them. Connect all of them to ground on the carrier board.

Power Sequence​

The module and the carrier board must power up and down in a defined order, controlled by POWER_EN, SYS_RESET* and SHUTDOWN_REQ*. A carrier board designed for the Jetson TX2 NX follows this sequence.

Power up. The carrier board supplies VDD_IN and drives POWER_EN high. It waits until the module releases SYS_RESET* before it enables its own supplies. The module releases SYS_RESET* when its power-up is complete, and the system boots.

Power down. The carrier board always carries out the shutdown, by driving POWER_EN low. When the module needs to shut down, for example because it is too hot, it drives SHUTDOWN_REQ* low, and the carrier board should then drive POWER_EN low as soon as possible. The module then asserts SYS_RESET*, and the carrier board may switch off its supplies. The 3.3 V I/O of the SoC must fall to 0.5 V or lower within 1.5 ms after SYS_RESET* is asserted, and the 1.8 V I/O within 4 ms.
