CXP5080
CMOS 4-bit Single Chip Microcomputer
Description
CXP5080 is a CMOS 4-bit single chip microcomputer
of piggyback/evaluator combined type which has
been developed for functional evaluation of the
CXP5084/5086.
Features
• Instruction cycle 3.8µs/4.19MHz (CXP5080)
1.9µs/4.19MHz (CXP5080H)
• ROM capacity Maximum 8K bytes (EPROM 27C64, LCC/DIP type 27C64)
• RAM capacity 400 × 4 bits (Including stack, display area)
• 32 general purpose I/O ports
• 16 large current output ports
• LCD controller/driver (Enables to direct drive)
— Enables to specify the segment output of 24, 20 and 16 optionally
— Enables to select program of the duty, 1/2, 1/3 and 1/4
— 1/3 bias
• 2 external interruption input pins
• 8-bit timer, 8-bit timer/event counter and 18-bit time base timer, independently controlled
• Arithmetic and logical operations possible between the entire RAM area, l/O area and the accumulator by
means of memory mapped I/O
• Reference to the entire ROM area is possible with the table look-up instruction
• 2 kinds of power down modes of sleep and stop
• Power on reset circuit (mask option)
• The oscillation circuit may be optionally specified as the crystal oscillation type or the CR oscillation type
• 64-pin ceramic SDIP/QFP
Note) Mask options are determined according to the CXP5080 category.
For details refer to the product list.

Pin Assignment 1 (Top View) 64 pin PSDIP Package
Note) PESEL pin serves to switch the I/O signal of the socket on top of the package from interface with the
evaluator (Eva mode) to interface with EPROM (Piggyback mode).
Setting PESEL pin to H Ievel brings Eva mode to enable the connection with the evaluator. Setting it to
L level brings piggyback mode to enable the mounting of EPROM. For QFP piggyback, it is necessary
only to exchange EVACAP (or EPROM) for EPROM (or EVACAP) and no other special measures are
required.
