LC662104A, 662106A, 662108A
Four-Bit Single-Chip Microcontrollers
with 4, 6, and 8 KB of On-Chip ROM
Overview
The LC662104A, LC662106A, and LC662108A 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 30-pin
package.

We recommend the use of reflow-soldering techniques to solder-mount MFP 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).

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.
