CXP86490

CXP86400/86490 CMOS 8-bit Single Chip Microcomputer Description The CXP86400/86490 are CMOS 8-bit single chip microcomputers that serve as both piggyback and evaluator. The CXP86400/86490 are developed for evaluating the function of the CXP86440/86448/86460. Note that the CXP86400 corresponds to the fixed font and the CXP86490 corresponds to the custom font respectively. 64 pin PQFP (Ceramic) Piggyback/ evaluator type 64 pin PSDIP (Ceramic) Features A wide instruction set (213 instructions) which covers various types of data Structure – 16-bit operation/multiplication and division/ Boolean Silicon gate CMOS IC bit operation instructions Minimum instruction cycle 250ns at 16MHz operation 122µs at 32kHz operation Applicable EPROM LCC type 27C512 (Maximum 60K bytes are available.) Incorporated RAM 1536 bytes (Excludes VRAM for on-screen display and sprite RAM) EPROM for custom font (CXP86490 only) LCC27C512 (Maximum 12K bytes are available.) Peripheral functions – A/D converter 8 bits, 6 channels, successive approximation method (Conversion time of 1.6µs at 16MHz) – Serial interface 8-bit clock sync type, 1 channel – Timer 8-bit timer 8-bit timer/counter 19-bit time base timer 32kHz timer/ counter – On-screen display (OSD) 12 × 16 dots, 384 character types, 15 character colors, 24 characters × 2 lines frame background 8 colors/half blanking background on full screen 15 colors/half blanking edging/shadowing/rounding for every line background with shadow for every ch...
