• Configuration Memory 256Mbit QSPI

• Done LED

• Two user LED

• USB JTAG - Connector needed on carrier board

• 100 MHz Oscillator

• Reset Button

• Boot selection header (JTAG/QSPI )

• PSRAM – 32Mbit – Seral RAM connected to the FPGA

• 82 IO including – Power and Ground, JTAG, 32 IO at 3v3, 41 IO configurable voltage (3v3-1.2V and LVDS) 

• RISC-V Microcontroller IP available

• Size : 59mm x 59mm

 

Typical applications include  

• System Controller – Power supply sequencing, power monitoring, configuration management, board management and supervision / communication interface.

• Protocol conversion – Convert to and from bespoke / legacy protocol.

• Sensor Aggregation – Aggregate several different sensor types for easy access by processor

• IO expansion – Provide additional interfaces e.g. QSPI, SPI, I2C etc.

• Processing offloading – e.g. Control algorithm e.g. PID, Filtering, co processing , encryption / decryption of data streams entering and leaving system

• Health and Usage Monitoring systems – Integrate with sensors e.g. accelerometer, pressure, humidity etc to monitor the environmental operating conditions.

• Rapid Prototyping – quickly demonstrate the concept required in an FPGA.
