The Trenz Electronic TE0823 (3PIU1FA /3PIU1FL)  is an industrial-grade MPSoC module integrating a low power Xilinx Zynq UltraScale+ MPSoC, 1 GByte LPDDR4 SDRAM, 8 GB eMMC chip, 2x 64 MB Flash memory for configuration and operation, and powerful switch-mode power supplies for all on-board voltages. A large number of configurable I/O's is provided via rugged high-speed stacking connections.  The module is equipped with a Lattice Mach XO2 CPLD for system controlling. 3x Robust high-speed connectors provide a large number of inputs and outputs.

The highly integrated modules are smaller than a credit card and are offered in several variants at an affordable price-performance ratio. Modules with a 4 x 5 cm form factor are completely mechanically and largely electrically compatible with each other.

All parts are at least industrial temperature range. The module operating temperature range depends on customer design and cooling solution. Please contact us for options.

Quad SPI Flash Memory

The TE0821 is equipped with dual Flash Memory, U7, U17.  Two quad SPI compatible serial bus flash memory chips are provided for FPGA configuration file and data storage. After configuration completes the remaining free memory can be used for application data storage. All four SPI data lines are connected to the FPGA allowing x1, x2 or x4 data bus widths to be used. The maximum data transfer rate depends on the bus width and clock frequency.

USB2.0 Transceiver

Hi-speed USB ULPI PHY (U18) is provided with USB3320 from Microchip. The ULPI interface is connected to the Zynq PS USB0 via MIO52..63, bank 502. The I/O voltage is fixed at 1.8V and PHY reference clock input is supplied from the on-board 52.00 MHz oscillator (U14).

eMMC Flash Memory

eMMC Flash memory device(U6) is connected to the ZynqMP PS MIO bank 500 pins MIO13..MIO23. eMMC chips IS21ES08G-JCLI (FLASH - NAND Speicher-IC (64 Gb x 1) MMC ) is used.

Programmable Clock Generator

There is a Silicon Labs I2C programmable clock generator Si5338A (U10) chip on the module. It's output frequencies can be programmed using the I2C bus address 0x70 or 0x71. Default address is 0x70, IN4/I2C_LSB pin must be set to high for address 0x71.

A 25.00 MHz oscillator is connected to the pin IN3 and is used to generate the output clocks. The oscillator has its output enable pin permanently connected to 1.8V power rail, thus making output frequency available as soon as 1.8V is present. Three of the Si5338 clock outputs are connected to the FPGA. One is connected to a logic bank and the other two are connected to the GTR banks.

Once running, the frequency and other parameters can be changed by programming the device using the I2C bus connected between the FPGA (master) and clock generator (slave). For this, proper I2C bus logic has to be implemented in FPGA.
