Product Overview:
Renesas Electronics had earlier launched the SH7260 Series ofmicrocontrollers, built around the SH2A-FPU 32-bit CPU core with superbrealtime processing capability, as a solution for the digital audio field. TheSH7262 and SH7264 belong to the SH7260 Series of microcontrollers, and themaximum operating frequency of 144 MHz enables faster operation in applicationssuch as equipment control or digital audio signal processing.This combinationof excellent signal processing performance and ROM code efficiency means thatcompression and decompression of audio data in formats required by digitalaudio applications, such as MP3, WMA, or AAC (Advanced Audio Coding), isperformed more quickly and program sizes are reduced. Thanks to the newly addedlarge-capacity SRAM, not only processing tasks related to equipment control anddigital audio, but also video display capabilities can be implemented on asingle chip. An ample 1 Mbyte or 640-Kbyte of on-chip SRAM is provided forvideo display use. It can be configured as a frame buffer to store video datatemporarily, which is necessary when implementing graphical displaycapabilities. The generous SRAM capacity means that it is possible to use a TFTLCD panel display up to WQVGA size (480 × 240 pixels) without the need forexternal SDRAM as video memory.
The SH7262 and SH7264 provide a new video display controller and digitalvideo input pins for use with graphical and video display applications.DigitalRGB output pins allow output of images or video in RGB565 format at up to WQVGAsize (480 × 240 pixels).
This reduces the total number of devices required and helps lower both thecost and the power consumption of the system.
