Note: 1. Applies to open drain output specification pins. The rating from the "other pin" entry applies for specifications other than the open drain output specification.
2. Levels up to the free-running oscillation level are allowed for the oscillator input and output pins.
3. Inflow current (For P8, the CMOS output specifications apply.)
4. Outflow current (Applies to pull-up output specification and CMOS output specification pins except P8.)
5. We recommend using reflow soldering methods to mount the QFP package version.
   Contact your Sanyo sales representative to discuss process conditions if techniques in which the whole package is immersed in a solder bath (solder dip or spray techniques) are used.


Description

The LC66556B and LC66558B are four-bit single-chip CMOS microcontrollers that integrate on a single chip all the functions required in a microcontroller, including ROM, RAM, I/O ports, two serial interfaces, comparator inputs, three-value inputs, timers and interrupts. These products are provided in a 64-pin package.

These products differ from the earlier LC66558A Series in the power supply voltage range and certain other electrical characteristics.
