RS Components introduces RX23E-A analogue front-end microcontrollers from Renesas for precision sensing and measurement applications

Advanced single-chip solutions integrate analogue circuitry and microcontroller to deliver better than 0.1% precision for a wide range of sensing and measurement equipment for manufacturing and test applications

LONDON, UK, 23 June 2020 – RS Components (RS), a trading brand of Electrocomponents plc (LSE: ECM), a global omni-channel solutions partner for industrial customers and suppliers, has introduced a new series of single-chip devices from Renesas, the RX23E-A microcontrollers (MCUs) which combine an analogue front end (AFE) and an MCU core for use in equipment that delivers high-precision measurements of analogue signals, such as temperature, pressure, weight, or flow.

Designed for manufacturing and test and measurement equipment, such as sensing or force measuring devices or temperature controllers, the RX23E-A group of MCUs offer better than 0.1% precision without calibration. In addition, the high level of integration offered by these MCUs with high-precision sensor measurement, computation, control and communications on a single chip, means equipment makers can reduce their bill-of-materials, save board space and simplify system design.

Integrating dual 24-bit delta-sigma A/D converters with up to 23-bit effective resolution, and programmable data rates from 7.6-sample/s up to 15,625-ksample/s, other specific leading-edge features of the AFE include offset drift of 10nV/°C, gain drift of 1 ppm/°C, an RMS noise of 30nV (rms). These characteristics enable the significant reduction of noise and temperature to the exceptionally low levels required for manufacturing applications, for example, which need to measure a wide variety of sensor data accurately and reliably.

The digital part of the RX23E-A devices is based on an advanced RXv2 core, which features operating speeds of 32MHz and excels at DSP and FPU (floating point unit) operations. The microcontroller also enables adaptive control techniques using temperature data and inverse matrix calculations based on six-axis distortion data, which can make it ideal for robot-arm force sensors in industrial manufacturing applications.

The Renesas RX23E-A MCUs are shipping now at RS in the EMEA and Asia Pacific regions.

Overcoming Signal Integrity Challenges of 112G Connections on PCB

Sponsored by Cadence Design Systems

One big challenge with 112G SerDes is handling signal integrity (SI) issues. By the time the signal winds its way from the transmitter on one chip to packages, across traces on PCBs, through connectors or cables, and arrives at the receiver, the signal is very distorted, making it a challenge to recover the clock and data-bits of the information being transferred. Learn how to handle SI issues and ensure that data is faithfully transmitted with a very low bit error rate (BER).

Thermocouple Temperature Sensor Solution

Sponsored by Mouser Electronics and Microchip

When it comes to temperature monitoring and management, industrial applications can be extremely demanding. With temperatures that can range from 270 to 3000 C, consumer-grade temperature probes just don’t cut it. In this episode of Chalk Talk, Amelia Dalton chats with Ezana Haile of Microchip technology about using thermocouples for temperature monitoring in industrial applications.
