Note: 1. Applies to pins with open-drain output specifications. For pins with other than open-drain output specifications, the ratings in the pin column for that pin apply.
2. For the oscillator input and output pins, levels up to the free-running oscillation level are allowed.
3. Sink current
4. Source current
5. 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).
DescriptionThe 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
