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 (Applies to pins with pull-up output and CMOS output specifications.)
5. 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).


Description

The LC66354C, LC66356C, and LC66358C are 4-bit CMOS microcontrollers that integrate on a single chip all the functions required in a system controller, including ROM, RAM, I/O ports, a serial interface, comparator inputs, three-value inputs, timers, and interrupt functions. These three microcontrollers are available in a 42-pin package.

These products differ from the earlier LC66358A Series and LC66358B Series in the power-supply voltage range, the operating speed, and other points.
