DHCOM iMX6ULL-D2

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.

2x CAN interface [3] 2x SPI interface [2] 2x I²C interface I²S Audio codec (1 x microphone, 1 x Line in, 1x Line out) [5] Real-time clock (I²C connection), low power temperature compensated 2x 10 bit analog input (I²C connection) 2x 256 Bytes EEPROM with integrated MAC address PWM channel 22 GPIOs (A-U + INT_HI_PRIO) JTAG debug connection via FFC plug connector Industrial temperature range (-40°C to +85°C) SODIMM-200 socket with DHCOM pin assignment
