Semiconductor manufacturer Renesas Electronics Corp. and its subsidiary Renesas Mobile Corp. are working on a new 32bit MCU. According to Renesas, the SH7734 offers improved graphics and network functionality for automotive, industrial and consumer applications.

The MCU has an Open VG conformant graphics accelerator and a Gigabit Ethernet controller. Its built-in Open VG 1.1 (Note 1) 2D graphics display functions allow animation-like displays with minimal memory requirement, hence improving human-machine interfaces (HMI) in application equipment.

The SH7734 MCU's built-in Ethernet controller offers a data rate of 1 gigabit-per-second (Gbps) for high-speed data communications, Renesas said. It added that 16 versions of the SH7734 will be available including offerings with and without an SD memory card interface to support higher performance systems and system miniaturization.

According to Renesas, there is a strong demand for equipment that includes a display with advanced graphics functionality. Other than LCD panels, a growing number of products from OA equipment, home appliances, games and to security systems are now getting information from multiple external sources over a network and display it in a variety of different ways.

This has created a strong demand for graphics functions such as those in the Open VG to implement even more complex HMIs, the company said. To address these needs, single-chip solutions are required that not only provide high-functionality and high resolution display functions and high-speed network connectivity, but also integrate powerful peripheral functions that can contribute to system miniaturization.

Renesas is confident that the SH7731 MCU, with its Open VG conformant graphics accelerator and a Gigabit Ethernet controller, will meet today's market requirements.

The microcontroller also offers processing speed that is 1.6 times faster than Renesas Electronics' existing MCUs and Built-in DDR2 and DDR3 SDRAM memory controller.

Samples of the SH7734 MCU will be available in November and with mass production set to start in March next year. Renesas is confident that it could hit production volume of 100,000 units per month by September 2012.
