Scope
This is also the right page for the DHCOR module, because DHCOM is the reference design for the DHCOR module.
Hardware
|
|
- Cortex-A7 NXP i.MX6ULL up to 900 MHz
- 128 - 1024 MByte NAND flash memory (8 bit bus width) or
4 - 16 GByte eMMC flash (8 bit bus width)
- 2 MB SPI boot flash
- 128 - 1024 MByte DDR3-400
- On module microSD card socket (4 bit SDIO) [1]
- LC display controller, 18 bit colors, 1366x768 pixels
- On-chip touch controller for 4-wire resistive touch screens
- 2x Ethernet controller 10/100 Mbit, IEEE1588 conform [2]
- USB 2.0 OTG high-speed
- USB 2.0 host high speed
- 2x Standard UART with hardware handshake support [3][4]
- WiFi iEEE802.11b/g/n + Bluetooth v4.1 (BR/EDR/BLE) module on BGA [1][4]
[1] On module microSD card socket is only available if WiFi is not mounted.
[2] The second SPI is only available, if the second ethernet is not mounted.
[3] CTS and RTS of the first UART is only available if second CAN port is not connected.
[4] The second UART is only available if Bluetooth is not used. This means WiFi/BT module 1DX is not mounted or module 1FX (only WiFi) is mounted.
[5] I²S lines are shared with JTAG.
