Modules list
2.1 Recommended connections for unused interfaces
The recommended connections for unused analog interfaces can be found in the Section, “Unused
Input/Output Terminations,” in the hardware development guide for the device.
UART1
UART2
UART3
UART4
UART Interface Each of the UARTv2 modules supports the following serial data
transmit/receive protocols and configurations:
• 7- or 8-bit data words, 1 or 2 stop bits, programmable parity (even,
odd, or none)
• Programmable baud rates up to 4 Mbps. This is a higher max
baud rate relative to the 1.875 MHz, which is stated by the
TIA/EIA-232-F standard.
• 32-byte FIFO on Tx and 32 half-word FIFO on Rx supporting
auto-baud
uSDHC1
uSDHC2
SD/MMC and SDXC
Enhanced Multi-Media Card /
Secure Digital Host Controller
The i.MX 8M Dual / 8M QuadLite / 8M Quad SoC characteristics:
All the MMC/SD/SDIO controller IPs are based on the uSDHC IP.
They are designed to support:
• SD/SDIO standard, up to version 3.0.
• MMC standard, up to version 5.0.
• 1.8 V and 3.3 V operation, but do not support 1.2 V operation.
• 1-bit/4-bit SD and SDIO modes, 1-bit/4-bit/8-bit MMC mode.
One uSDHC controller (SD1) can support up to an 8-bit interface, the
other controller (SD2) can only support up to a 4-bit interface.
USB 3.0/2.0 2x USB 3.0/2.0 controllers and
PHYs
Two USB controllers and PHYs that support USB 3.0 and USB 2.0.
Each USB instance contains:
• USB 3.0 core, which can operate in both 3.0 and 2.0 mode
VPU Video Processing Unit A high performing video processing unit (VPU), which covers many
SD-level and HD-level video decoders. See the i.MX 8M Quad
Applications Processor Reference Manual (IMX8MQRM) for a
complete list of the VPU’s decoding and encoding capabilities.
WDOG1
WDOG2
WDOG3
Watchdog The watchdog (WDOG) timer supports two comparison points
during each counting period. Each of the comparison points is
configurable to evoke an interrupt to the Arm core, and a second
point evokes an external event on the WDOG line.
XTALOSC Crystal Oscillator interface The XTALOSC module enables connectivity to an external crystal
oscillator device.
