Description
The CXP508L4/508L6 is a CMOS 4-bit micro-
64 pin SDIP (Plastic)
64 pin QFP (Plastic)
computer which consists of 4-bit CPU, ROM, RAM,
I/O port, 8-bit timer, 8-bit timer/counter, 18-bit time
base timer, 8-bit serial I/O, vector interruption, and a
liquid crystal displayer (LCD) controller/driver. They
are integrated into a single clip with the standby
function etc. which are to be operated at low power
consumption.
Features
• Instruction cycle 4µs/2MHz (2.4V to 3.5V)
• ROM capacity 4.096 × 8 bits (CXP508L4)
6.144 × 8 bits (CXP508L6)
• RAM capacity 400 × 4 bits
(24 × 4 bits is used in combination
with the LCD display memory)
• 32 general purpose I/O ports
(For 16 segment outputs)
• LCD controller/driver (Direct drive possible)
— Optical specification of 24, 20 or 16 segment
outputs
— 1/2, 1/3, 1/4 duty selectable through program
— 1/3 bias
• 2 external interruption input pins
• 8-bit/4-bit variable serial I/O
• 8-bit timer, 8bit timer/event counter and 18-bit time
base timer are independently controllable
• Arithmetic and logical operations possible between
the entire RAM area, I/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 types of power down models, sleep and stop
• 64-pin plastic SDIP/QFP available
• Piggy back package (CXP5080) available
