The Versal adaptive SoC standard I/O peripherals are in the low-power domain (LPD) and in the PMC. Configure the NoC to provide access to the DDR memory controller. This allows peripherals with direct memory access (DMA) to access the DDR memory interfaces.
The following table shows the difference between the standard peripherals in Zynq UltraScale+ MPSoCs and Versal adaptive SoCs.
| Peripheral | Zynq UltraScale+ MPSoC | Versal Adaptive SoC |
|---|---|---|
| CAN, CAN-FD | 2 controllers with standard CAN | 2 controllers with controller area network - flexible data rates (CAN-FD) |
| GEM | 4 controllers | 2 controllers with time-sensitive networking (TSN) feature |
| GPIO | 1 controller | 2 controllers |
| I2C | 2 controllers | 2 controllers in LPD (general purpose) 1 controller in PMC (general purpose) |
| NAND | 1 controller | N/A |
| PCIe 1.0 and 2.0 | 1 controller | N/A |
| PCIe 3.0 and 4.0 | 1 controller | Varies by device |
| SPI | 2 controllers | 2 controllers |
| SATA | 1 controller | N/A |
| UART | 2 controllers with standard UART | 2 controllers with Server Base System Architecture (SBSA) |
| USB (host, device, dual-role device) | 2 USB 2.0/3.0 controllers | 1 USB 2.0 controller |
