Multilayer PCB for BGA package

SH726x incorporates LCD driver capability => save up to €2

SH726x incorporates up to 2.5MB of SRAM => save up to €1.5

SH726x boots from SPI flash (no need for NOR) => save up to €0.5

SH726x in a QFP package for lower cost PCB => save up to €1

Could you save up to 4.5€ on your HMI application?* Prices are approximations and could vary depending your application

On-chip large-capacity RAM


Internal SRAM with 2.5Mbyte capacityDue to big SRAM - same easy usage as a FLASH device

Booting from a real low cost serial SPI Flash < 0.20€After boot forget the serial Flash –> work from internal SRAMAfter boot a it’s a real one Chip Solution – no external RAM, no NOR, no NAND

Lower BOM and PCB costsQFP package allows 2 layer PCBssmaller PCBs due to reduced external componentsSmaller failure rates due to reduced external components

Enhanced Graphics performanceenough SRAM for double frame buffers, video buffer and program codeOpenVG 1.1 Vector Graphics Accelelerator – fully compliant to Khronos API SVGA LCD controller with 3 layers for alpha blending and chroma keying blendingCMOS camera interface for video recording

OthersGood connectivity with USB, CAN and IEBUSGood family concept w & w/o CAN & IEbus and 2 different memory configurations Its a lot of SRAM onCHIP BUT its cheaper than expected

Renesas SH2A optimized JPEG library

Very useful for MotionJPEG (MJPEG) animations MJPEG is commonly known on picture cameras for video recording

JPEG Compression by Base-line Method Compress & Expand Full Color Data (24-bit/pixel) by about 1/10 to 1/20 Conversion Speed

Compression: About 0.37 Second (SH7261@80MHz) Expansion: About 0.28 Second (SH7261@80MHz) Sampling Ratio: Y : Cb : Cr = 4:1:1 VGA(640dots x 480dots x 3): About 460,000 Pixels

Compact Size Encode: ROM about 4.4KB / RAM about 1.2KB Decode: ROM about 4.4KB / RAM about 4.7KB

SH2A CPU could be used for MJPEG en- and decoding compress video stream from external camera to allow proper storage playback of MJPEG video from other sources
