Multi-Sensor Platform for ASi-5

Customers often want to quickly evaluate ASi-5 together with several sensors in their lab. The ASi-5 board already exists but is lacking sensors, so a dedicated I/F is required to connect to the appropriate sensors.

They often also need to decouple processes and offload their host MCU, so a pre-evaluation of the sensor data by a dedicated MCU on the sensor board is often required. A power supply, usually 3.3V or 5V, is also required.

This design shows a single PCB with multiple sensors, interfaces, a dedicated MCU for sensor data pre-evaluation, and a power supply.

System Benefits:

• Multiple sensors on one board for quick evaluation
  • Sensor selection by DIP switch or by software
  • Additional analog inputs
• Integrated powerful, rich analog features in the RA2A1 MCU for sensor data pre-evaluation/calculation
  • I/F to existing ASi-5 board
  • 8-/16-/24-bit parallel out for simple ASi-5 slave
  • SPI for complex ASi-5 slave
  • Additional PMOD I/F to also allow connection to most Renesas MCU boards
• Single 3.3V or 5V input and internal generation of additional power rail (3.3V + 5V)
