Sensor Signal Conditioner to Linearize Results

In this solution from Renesas, workload is done in a sensor signal conditioner to allow close to 100% use of the MCU for applications

Image of Renesas' Sensor Signal Conditioner to Linearize ResultsRenesas’ winning combination reference design for sensor signal conditioner (SSC) is used to linearize sensor elements. In scales, the used sensor elements are non-linear; therefore, linearization is required. In this solution, workload is done in a sensor signal conditioner to allow close to 100% use of the microcontroller (MCU) for customer applications.

Features
  • No load for the MCU as all the pre-processing is done by the signal conditioner
  • Tiny software footprint on the MCU side for precise scale functionality
  • Reduced BOM, smaller PCB
  • The IO-Link PHY powers the entire application
  • Easy adoption of a seven-segment LED via the GreenPAK™ family of cost-effective NVM programmable devices
  • ZIOL2401 IO-link line driver
    • Dual-channel IO-link HV line driver with integrated DC/DC
  • Offloading the MCU offers full MCU capability for user applications
  • RL78/G14 microcontroller
    • Low power, high function, general purpose microcontrollers for motor control, industrial, and metering
  • SLG46537 programmable mixed-signal devices
    • Programmable mixed-signal matrix with asynchronous state machine
  • ZSSC3240 SSC
    • High-end 24-bit SSC with analog and digital output
Applications
  • Industrial scales
  • Point-of-sale (POS) systems
  • Retail scales
