Renesas Develops RJ45 Ethernet Socket With Entire Ethernet Controller Embedded Into It

Renesas Electronics Corporation, a significant supplier of advanced semiconductor solutions, announced its latest industrial Ethernet module solution, the I-RJ45. It combines a single- or dual-port RJ45 connector and simplifies integration for industrial Ethernet by supporting various industrial network applications including sensors and transmitters, gateways, operator terminals and remote I/O.

This new device is an intelligent RJ45 module that comes with specialized embedded software that supports multiple industrial Ethernet protocol stacks. The software package and sample codes provide system manufacturers with a complete set of tools and frameworks to build their application. This helps to prototype systems, reducing the time needed for industrial network protocol integration. The modules are 50 x 17.5 x 12mm (single) and 50 x 35 x 12mm (dual).

With a general Application Programmable Interface (API), the application can easily be connected to the protocol software. It offers a seamless integration path to other Renesas ASSP solutions. The single-port version of the RJ45 module is based on the RX64M microcontroller (MCU) Group and the dual-port module solution includes the R-IN32M3 industrial Ethernet communication chip.

Renesas also offers a solution kit version of the module that consists of a single or dual-port industrial Ethernet module attached to an adapter board for development. This adapter board enhances the module to connect with Arduino and Pmod interfaces, which enables it to connect to other Renesas MCU development boards including Renesas Synergy™ and RX. The Ethernet module solution kit also includes a quick start-up guide, a USB cable and a CD with software and documentation.

Samples of the I-RJ45 industrial Ethernet module solution are now available worldwide. The mass production is scheduled to begin in Q3, 2018. The industrial Ethernet module solution kit may be available in April 2018 and projected price of €299.00 per kit.

DIY I2C LCD Display

FKPROHGII94PPRL.LARGE

sspence @ instructables.com shows how to interface a character LCD using I2C and only two IO pins.

The typical parallel LCD used with an Arduino (16×2 or 20×4) has 16 pins. Only 6 I/O pins are required on the Arduino, but what if you could get that down to two I/O pins, and still have those pins available for other devices?

The I2C interface is on pins A4 and A5 of the Arduino. These are addressable, and are therefore shareable with other I2C devices that have different addresses.
