=== Quad-SPI ===

Quad-SPI is used to access multi-bit serial flash memory devices for high throughput and low pin count applications. The controller operates in one of three modes: I/O mode, linear addressing mode, and legacy SPI mode. The following table describes the interface signals:

=== Static memory controller ===

Static memory controller (SMC) signals are routed to the connectors to connect an external flash NAND memory chip. The following table describes the interface signals:

=== I²C0 ===

This I²C module is a bus controller that can function as a master or a slave in a multi-master design. It supports an extremely wide clock frequency range up to 400 Kb/s. I²C0 is internally connected to the following devices:

* [[Thermal IC (Bora)|Thermal IC]]: Texas Instruments TMP421 (Address: 0x4F)

=== SD/SDIO ===

The SD/SDIO controller controller is compatible with the standard SD Host Controller Specification Version 2.0

Part A2. The core also supports up to seven functions in SD1, SD4, but does not support SPI mode. It does support SD high-speed (SDHS) and SD High Capacity (SDHC) card standards. The SD/SDIO controller also supports MMC3.31.

=== CAN ===

CAN port is connected to on-board transceiver (TI SN65HVD232) which converts the single-ended CAN signals of the controller to the differential signals of the physical layer. The following table describes the interface signals:
