For detailed information about the current function of the MIO-pin in conjunction with the SC CPLD, the internal signal assignment and implemented logic, refer to the Wiki reference page of the SC CPLD firmware of this board or into the bitstream file of the SC CPLD.

The PS_1V8 and VCCINT_0V85 voltage levels are monitored by the voltage monitor circuit U89, which generates the POR_B signal to RESET the board. A manual reset is also possible by driving the pin 'MR' on SC CPLD, bank 4, pin L7 to GND.

The 125MHz PHY output clock (PHY_CLK125M) is routed to System Controller CPLD U27, bank 4, pin K2.

8-Channel I²C Switches

All on-board and on-module peripherals with accessible I²C interface are muxed to the I²C interface of the Zynq Ultrascale+ MPSoC as master.

For this purpose, the TEB0911 board is equipped with two 8-channel I²C switches provided by TCA9548A from Texas Instruments, together creating up to 16 switched I²C channels.

Refer to the data sheet of the TCA9548A chip how to address and and transmit data to the I²C slave devices through this switches.

The on-board I²C bus works with reference voltage 3.3V, it is connected to the MPSoC I²C interface via PS MIO bank (pins MIO38, MIO39) and configured as master.

Table 46: MIO-pin assignment of the module's I²C interface

The I²C switches can be reseted simultanously by the pin 'I2C_RST', which is connected to SC CPLD U27, bank 4 pin L2 with low active logic.

I²C addresses (7 bit without read/write-bit) for on-board slave devices are listed in the table below:

CAN FD Transceiver

On-board CAN FD (Flexible Data Rate) transceiver U48 is provided by Texas Instruments TCAN337. This controller is the physical layer of the CAN interface and is specified for data rates up to 1 Mbps. The controller has many protection features included to ensure CAN network robustness and to eliminate the need for additional protection circuits. Refer to the data sheet of this transceiver for more details and specifications.

The transceiver is connected to System Controller CPLD U27, means it works on this interface with 3.3V VCCIO. The logical signal processing of the CAN interface depends on the current firmware ot the SC CPLD.

On-board Flash Memory

On-board QSPI flash memory U24 and U25 on the TEB0911 board is provided by Micron Serial NOR Flash Memory N25Q256A with 256 Mbit (32 MByte) storage capacity each. The QSPI Flash memory ICs are connected to the PS MIO bank (Dual QSPI MIO0 ... MIO12) of the Zynq Ultrascale+ MPSoC. This non volatile memory is used to store initial FPGA configuration. Besides FPGA configuration, remaining free flash memory can be used for user application and data storage. All four SPI data lines are connected to the Zynq MPSoC allowing x1, x2 or x4 data bus widths. Maximum data rate depends on the selected bus width and clock frequency used.
