Page 31: Introduction To Circuit Boards
7.Introduction to Circuit Boards A: MAIN CHIP SUMMARY U11 M30620: 16-BIT CMOS SINGLE-CHIP MICROCOMPUTER The single-chip microcomputer operate using sophisticated instructions featuring a high level of instruction efficiency. With 1M bytes of address space, they are capable of executing instructions at high speed. In addition, this microcomputer contains a multiplier and DMAC which combined with fast instruction processing capability. - Page 32 U8 SAA7117: The SAA7117(A)E/H is a consequent derivate of SAA7118 X-VIP multistandard video decoder. In addition to its predecessor, it provides 10 bit A/D- conversion, enhanced PAL/NTSC comb filtering, more versatile VBI data processing,support of High Definition component video, picture improvement processing, and more robustness with VCR-type signals.
