Renesas Technology has introduced eight versions of the SH7266 and SH7267 32-bit MCUs with a 50% increase in on-chip SRAM size of 1.5Mbyte.

The intention of the increase in on-chip memory is 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.

The SH7266 and SH7267 are built around the SH2A-FPU CPU core (which incorporates an FPU), have a maximum operating frequency of 144MHz, and deliver excellent processing performance. The instruction set of the SH2A-FPU is backward compatible with the SH-2A and SH-2 CPU cores, allowing developers to reuse program code created for earlier products.

In addition, ROM code efficiency has been improved approximately 75% in comparison with the SH-2. As a result, the object code for the same program can be compressed to about three-quarters the previous size, conserving the memory capacity available for storing programs.

There is also a CD-ROM decoder and a sampling rate converter for converting the sampling frequency for audio data are implemented on-chip.
