CXP85290A

CXP85200A/85290A CMOS 8-bit 1-chip Microcomputer Description The CXP85200A/85290A are CMOS 8-bit 1-chip microcomputers that serve as both piggyback and evaluator. The CXP85200A/85290A is developed for evaluating the function of the CXP85112B/85116B/ 85220A/85224A/85228A/85232A. Note that CXP85200A corresponds to the fixed font, and CXP85290A corresponds to the custom font respectively. 64 pin PSDIP (Ceramic) Piggyback/ evaluator type 64 pin PQFP (Ceramic) 64 pin PSDIP (Ceramic) Features 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.
