Onboard Interfaces and Devices

6.1

DRAM

The conga-SMX8-X offers up to 32 bit LPDDR4 onboard SDRAM @ 1200 MHz.
section 1.2.1 "Options Information".
Note
1. The conga-SMX8-X module variants with NXP i.MX 8DualX only support 16 bit LPDDR4 onboard SDRAM @ 1200 MHz.
6.2

eMMC

The conga-SMX8-X offers an onboard eMMC 5.1 HS400 storage device with up to 128 GB (16 GB assembled by default). Changes to the onboard
eMMC may occur during the lifespan of the module in order to keep up with the rapidly changing eMMC technology. The performance of the
newer eMMC may vary depending on the eMMC technology.
Note
For adequate operation of the eMMC, ensure that at least 15 % of the eMMC storage is reserved for vendor-specific functions.
6.3

SPI NOR Flash

The conga-SMX8-X offers an onboard SPI NOR flash memory chip with up to 128 Mbit (64 Mbit assembled by default). The SPI NOR flash
memory chip is connected to the QSPI_A port of the SoC.
6.4

Wi-Fi and Bluetooth

Optionally, the conga-SMX8-X can offer Wi-Fi and Bluetooth connectivity via an onboard H&D Wireless SPB228 M.2 1216 module instead of
USB4 (assembly option).
USB4 is recommended but it is also possible to connect the module via SDIO (instead of SDIO pins), PCI Express (instead of PCIE_A pins), or
Serial Port (instead of SER2 pins; can only be used for BT).
Note
PN: 051104 offers Wi-Fi/BT instead of USB4 pins by default.
