Refer to 'electrical characteristics' on the semiconductor news.
Port format of the LC86P4564 during the reset is identical to that of the LC864532/28/24/20/16/12/08.
The LC86P4564 uses 256-byte spaces addressed 0FF00H to 0FFFH in the program memory to set options. In this way, all options
of the LC864500 series cannot be executed.
Some of the LC864500 series options, which the LC86P4564 can support are as shown in the table below.
LC86P4564 options
Option types Pins, circuits Contents of the option
Input/output specifications
of input/output ports
Pull-up MOS transistor of
input port.
*1) Specified in bit units
*2) When the "CMOS output" is selected as an output format, the pull-up MOS transistor will be provided, and when the "n-
channel open-drain output" is selected, the pull-up MOS transistor will not be provided.
(2) Option setting program
The option data is written with the option specifying program "SU86K.EXE". The option data is linked to the program area by
the linkage loader "L86K.EXE".
LC864532/28/24/20/16/12/08
The program is executed from 00H of the
program counter as soon as a high-level signal
is applied to the reset terminal.
2.5 V to 6.0 V
LC86P4564
The option must be set internally within 3 ms
after a high-level signal is applied to the reset
terminal. In this period options are switched
gradually, and after that, the program is
executed from 00H of the program counter.
4.5 V to 5.5 V
