Processor and memory subsystem[edit | edit source]
The heart of ONDA module is composed by the following components:
- Xilinx Zynq Ultrascale+ XCZU5EG / XCZU5EV SoC
- Power supply unit
- DDR memory banks
- NOR and eMMC flash storage
- 3x 140 pin connectors with interfaces signals
This chapter shortly describes the main ONDA components.
Processor Info[edit | edit source]

PL info[edit | edit source]
The Zynq™Ultrascale+ MPSoCs h software, hardware, interconnect, power, security, and I/O programmability. The range of devices in the Zynq UltraScale+ MPSoC family allows designers to target cost-sensitive as well as high-performance applications from a single platform using industry-standard tools. EG and EV Zynq UltraScale+ devices contains the same PS, the PL, while only the EV device has a VCU hardware cell. The Zynq UltraScale+ MPSoCs are able to serve a wide range of applications including:
- Automotive: Driver assistance, driver information, and infotainment
- Wireless Communications: Support for multiple spectral bands and smart antennas
- Wired Communications: Multiple wired communications standards and context-aware network services
- Data Centers: Software Defined Networks (SDN), data pre-processing, and analytics
- Smarter Vision: Evolving video-processing algorithms, object detection, and analytics
- Connected Control/M2M: Flexible/adaptable manufacturing, factory throughput, quality, and safet
ONDA can mount two versions of the Zynq processor. The following table shows the main PL features:
| Processor | Programmable logic cells | LUTs | Flip flops | Distributed RAM | Total Block RAM | DSP slices | Serial Tranceivers | Peak Serial Transceiver performance |
| XCZU5EG / XCZU5EV | 256K Logic Cells | 117120 | 234240 | 3.5 Mb | 5.1 Mb | 1248 | 4 | 6 Gb/s |
RAM memory bank[edit | edit source]
DDR4 RAM memory bank is composed by 64-bit width chips. The following table reports the RAM specifications:
| CPU connection | Dynamic Memory Controller (DDRC) |
| Size max | 8 GB |
| Width | 64 bit with ECC |
| Speed | 3200 MHz |
NOR flash bank[edit | edit source]
NOR flash is a Serial Peripheral Interface (SPI) device. By default two devices are connected to both QSPI channel 0 and channel 1 for a dual parallel interface. They acts as boot memory. The following table reports the NOR flash specifications:
| CPU connection | PS MIO QSPI Channel 0 / 1 |
| Size min | 16 MB |
| Size max | 32 MB |
| Chip select | SS5 and SS7 |
| Bootable | Yes |
eMMC flash bank[edit | edit source]
On board main storage memory eMMC is connected to the PS MIO interface and it can act as boot peripheral. The following table reports the eMMC flash specifications:
| CPU connection | PS MIO SDIO0 |
| Size min | 8 GB |
| Size max | 128 GB |
| Bootable | Yes |
Power supply unit[edit | edit source]
ONDA embeds all the elements required for powering the unit, therefore power sequencing is self-contained and simplified. Nevertheless, power must be provided from carrier board, and therefore users should be aware of the ranges power supply can assume as well as all other parameters.
