Styx SODIMM includes DDR3L memory technology which is the third generation of DDR memory technology designed to operate at lower voltage levels (1.35 V) compared to standard DDR3 modules. Styx SODIMM uses two micron MT41K256M16TW-107 IT:P TR memory, has a capacity of 256 megabits (Mbits) organized into 16 million addresses., totaling 1 GB of RAM. DDR3L is connected to PS section of Zynq-7000 AP SoC and has the speed up to 1866 MT/s.

The Styx SODIMM has 128 Mb of Quad bit SPI flash memory. It is serial NOR flash which operates at the voltage of 3.3 V. SPI flash connects to the Zynq PS QSPI interface and serves as the Zynq SoC’s default boot device. QSPI flash memory can be increased to 8GB using eMMC flash (optional).

The Styx SODIMM incorporates two micro-SD card slots, with one located in the SODIMM itself (SD) and the other on the carrier board (SD0). SD0 can be used to store non-volatile external memory as well as to boot the Zynq-7000 AP SoC. Both the slots are connected to the PS MIO banks and eMMC flash can be multiplexed with SD pins.

Styx SODIMM supports eMMC Flash and is multiplexed with micro-SD card slot pins in SODIMM. It can be used as additional storage for SPI flash and as a secondary boot device. It operates at a voltage level of 3.3 V and supports up to 4 bit mode.

Styx SODIMM implements single-Chip 10/100/1000 Mbps Ethernet Transceiver, with 1.8 V operating voltage. It provides the Reduced Gigabit Media Independent Interface (RGMII) and is connected to the PS MIO bank in Zynq-7000 AP SOC.

Styx SODIMM support high speed USB 2.0 On-The-Go (OTG) transceiver in 24 MHz operating frequency. OTG technology supports both device and host modes. The ULPI (UTMI+ Low Pin Interface) protocol is utilized to establish a connection between MIO (Multi-Function Input/Output) pins and the PHY (Physical Layer) component.

The Trusted Platform Module(TPM) is an integrated security module for hardware authentication. The security module is used primarily for cryptographic key generation, key storage and key management as well as generation and secure storage for digital certificates.

Styx SODIMM includes Real Time Clock (RTC), an integral part of electronic devices that operates independently of the device to accurately track real-world time. It is connected to PL IO pins and has an operating voltage of 3.3 V.

Styx SODIMM features MAC ID EEPROM, which is a memory chip that stores the unique MAC address of a network interface. It is a non-volatile memory that interfaces with PS of Zynq-7000 AP SoC.  It operates at a voltage of 1.8 V.

Styx SODIMM have UART interface connected to PS UART peripheral of the device. UART offer a flexible and user-friendly solution for incorporating serial communication interfaces, facilitating seamless data exchange with external devices across a diverse array of applications.

Styx SODIMM offers I2C communication through PS I2C peripheral and offers a flexible and efficient solution for establishing communication with various peripheral devices using the I2C protocol. It has a operating voltage of 1.8 V.

Styx SODIMM includes a second generation high-speed CAN transceiver with an operating voltage of 3.3 V. It has a data rate of 8 Mbps in normal mode and is linked to PS MIO of Zynq-7000 AP SoC.

Styx SODIMM features one RGB LED which can be used for custom or debug purposes.

Programming the QSPI Flash for the Zynq series is slightly different than Series-7 FPGAs. There is a tutorial on how to flash and boot Styx from QSPI (as well as SD Card).
