Pin Function
Pin Description and Circuit
Pin Description
I/O
Connected to 2.2~4.5V power supply at KHz and MHz
version or 4.0 ~ 5.5V power supply at WIDE version.
Connected to 0V power supply.
Used to input a manual reset. When the pin goes "L",
the D-output ports and REMOUT-output port are initialized to
"L", and ROM address is set to address 0 on page 0.
For programming, this pin receives 12.5V programming
voltage.
4-bit input port.
STOP mode is released by "L" input of each pin.
The output is the structure of N-channel-open-drain.
4-bit I/O port. (Input mode is set only when each of them
output "H".)
In outputting, each can be set and reset independently(or at
once.)
The output is in the form of C-MOS.
STOP mode is released by "L" input of each pin.
High current output port.
The output is in the form of C-MOS.
The state of large current on is "H".
Oscillator input. Input to the oscillator circuit and connection
point for ceramic resonator.
Internal capacitors available at KHz version.
A feedback resistor is connected between this pin and OSC2.
Connect a resonator between this pin and OSC1.
