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.
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.
• 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

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
