Description
CXP85400/85490 CMOS 8-bit 1-chip Microcomputer Description The CXP85400/85490 are CMOS 8-bit 1-chip microcomputers that serve as both piggyback and evaluator. The CXP85400/85490 are developed for evaluating the function of the CXP85452/85460. Note that CXP85400 corresponds to the fixed font, and CXP85490 corresponds to the custom font respectively. 64 pin PSDIP (Ceramic) Piggyback/ evaluator type 64 pin PQFP (Ceramic) Features 64 pin PSDIP (Ceramic) Instruction set which supports a wide array of data types — 213 types of instructions which include 16-bit calculations, multiplication and division arithmetic, and boolean bit operations. Minimum instruction cycle 0.5µs/8MHz EPROM 27C512 LCC type 27C512 (Maximum of 60K bytes are available.) Incorporated RAM capacity 960 bytes EPROM for custom font (CXP85490 only) LCC type 27C256, LCC type 27C512 (used volume is 24K bytes) Peripheral functions — On-screen display function 12 × 18 dots, 384 types 15 colors, 32 characters × 12 lines Black frame output half blanking, shadow, background color on full screen/ half blanking Double scanning mode, jitter elimination circuit — I2C bus interface — PWM output 14 bits, 1 channel 8 bits, 8 channels — Remote control receiving circuit 8-bit pulse measurement counter, 6-stage FIFO — A/D converter 8 bits, 4 channels, successive approximation system (conversion time of 20µs/8MHz) — HSYNC counter 2 channels — Power supply frequency counter — Watchdog timer — Serial I/O 8-bit clock syn...
