Renesas MCU has on-chip Open VG graphics
6/6/2011 9:07 AM EDT
The SH7734 MCU from Renesas Electronics features an Open VG compliant graphics accelerator and a Gigabit Ethernet controller to provide graphics and network functionality suitable for automotive, industrial and consumer applications that include an LCD panel.
The built-in Open VG 1.1 2D graphics display functions, allowing animation-like displays to be implemented with minimal amounts of memory to improve human-machine interfaces in application equipment.
By including graphics display functions that conform to the Open VG 1.1 specifications, the SH7734 MCU can enable, with minimal memory and at high speed, visual effects such as animated display as well as enlargement, rotation, deformation, and colour gradation in figures and text.
The SH7734 also provides digital RGB output pins that can provide full-colour (16.77 million colours) WVGA size (800 × 480) or high-colour (65,536 colours) XGA size (1024 × 768) displays to support increases in the size and resolution of end product screens.
The MCU includes an on-chip Gigabit Ethernet controller, GMII (Gigabit Media Independent Interface) that complies with the IEEE 802.3 standard . The built-in Ethernet interface supports data rates of 10 and 100 Mbps and can also be connected to 1 Gbps (1000 Mbps) Ethernet LANs.
The MCU also incorporates a dedicated direct memory access controller to reduce CPU overhead and enable smooth, large-capacity data transfers.
The SH7734 uses an SH-4A CPU core operating at 533 megahertz (MHz) and is approximately 1.6 times faster than the existing SH7764 MCU. The SH7734 MCU can perform the audio processing, diverse display control operations, and signal processing required for high-functionality HMIs.
It also includes a built-in memory controller that supports DDR2 and DDR3 SDRAM with a maximum clock frequency of 300 MHz. The controller provides memory bandwidths of up to 1.2 gigabytes per second to support large-capacity data transfers.
The SH7734 MCU will be available in 16 versions that differ in the combination of SD memory card interface, CAN interface, and other hardware features.
It is provided in a lead-free 440-pin BGA package.
