Overview
The LC662516A, LC662512A, and LC662508A are 4-bit
CMOS microcontrollers that integrate on a single chip all
the functions required in a special-purpose telephone
controller, including ROM, RAM, I/O ports, a serial
interface, a DTMF generator, timers, and interrupt
functions. These microcontrollers are available in a 64-pin
package.
Features and Functions

set (128 instructions).
• I/O ports: 58 pins
• DTMF generator
This microcontroller incorporates a circuit that can
generate two sine wave outputs, DTMF output, or a
melody output for software applications.

We recommend the use of reflow-soldering techniques to solder-mount QFP packages.
Please consult with your Sanyo representative for details on process conditions if the package itself is to be directly
immersed in a dip-soldering bath (dip-soldering techniques).

I/O ports P20 to P23
• Input or output in 4-bit or 1-bit units
• P20 is also used as the serial input SI0
pin.
• P21 is also used as the serial output
SO0 pin.
• P22 is also used as the serial clock
SCK0 pin.
• P23 is also used as the INT0 interrupt
request pin, and also as the timer 0
event counting and pulse width
measurement input.
I/O ports P30 to P32
• Input or output in 3-bit or 1-bit units
• P30 is also used as the INT1 interrupt
request.
• P31 is also used for the square wave
output from timer 0.
• P32 is also used for the square wave
and PWM output from timer 1.
• P31 and P32 also support 3-state
outputs.
Hold mode control input
• Hold mode is set up by the HOLD
instruction when HOLD is low.
• In hold mode, the CPU is restarted by
setting HOLD to the high level.
• This pin can be used as input port P33
along with P30 to P32.
• When the P33/HOLD pin is at the low
level, the CPU will not be reset by a
low level on the RES pin. Therefore,
applications must not set P33/HOLD
low when power is first applied.
I/O ports P40 to P43
• Input or output in 4-bit or 1-bit units
• Input or output in 8-bit units when used
in conjunction with P50 to P53.
• Can be used for output of 8-bit ROM
data when used in conjunction with
P50 to P53.
