RX23E-A Group Channel-to-channel isolated analog measurement system
●This document describes a system which has 4 pieces of Renesas microcontroller RX23E-A measuring temperature or voltage synchronously with channel-to-channel isolation. RX23E-A in each unit samples output voltage of thermocouple/RTD or pin input voltage with built-in 24-bit Δ-ΣA/D converter (DSAD) in cycle of approximate 1 msec, performs filter processing, and converts to temperature or voltage.
●As an upper layer MCU, RX72M obtains temperature or voltage measured in each unit in cycles of 10 ms and transmits to PC via USB. As a result, 4-channel synchronous measurement can be realized within 1 ms.
●Communication between 4 pieces of RX23E-A and RX72M is performed by a single channel 3-wire serial communication, and individual communications with the specified unit address and the broadcast communication are performed. This can reduce isolators comparing to 4-wire SPI communication which uses chip select.
