Renesas Technology SH7266 and SH7267 MCUs – eight versions released

Renesas has released eight versions of the SH7266 and SH7267, two 32-bit MCUs with an on-chip SRAM size of 1.5 MB that are intended for embedded applications in the industrial and consumer fields, such as displays for digital audio players or graphical dashboards.

The devices are the enhanced products of the SH7260 series that belongs to the SuperH family of 32-bit RISC MCUs. They each have 1.5 MB of large-capacity on-chip SRAM, an increase of 50% from the 1 MB of earlier MCUs in the SH7260 series, to take the place of external synchronous DRAM (SDRAM).

This makes it possible to implement a VGA display (640 × 480 pixels) without the need for external SDRAM. The large-capacity SRAM can be used as a display frame buffer or as a work area for storing programs or data.

The SH7266 is available in a 144-pin QFP package and the SH7267 in a 176-pin QFP package. Their main features include: large capacity (1.5 MB) on-chip SRAM that eliminates the need for external SDRAM. Both have 1.5 MB of large-capacity on-chip SRAM that can be used in place of external SDRAM as a program or work area. The large-capacity SRAM can also be used as a display frame buffer for video data, eliminating the need to use external SDRAM for the frame buffer.

They provide a video display controller and digital video input pins for use with graphical and video display applications. It supports functionality such as video recording, size reduction, alpha blending effects (superimposition of transparent or semitransparent images), and superimposition of video input.

Digital RGB output pins allow output of images or video in RGB565 format (in which each colour is represented by 16 bits.

Peripheral functions allow high-speed USB 2.0 (host and function modes). In addition to standard serial interfaces such as serial communication interfaces with 16-stage FIFO and I²C bus interfaces, they are equipped with serial sound interfaces for digital audio data I/O, a CAN interface, 16-bit timers including CMT and MTU2 and PWM timers for motor control.
