Ordering number : EN4677 CMOS LSI LC66354B, 66356B, 66358B Four-bit Single-Chip Microcontrollers On-Chip 4 K/6 K/8 K-byte ROM Overview The LC66354B, LC66356B and LC66358B are 42-pin package four-bit CMOS microcontrollers that integrate on a single chip all functions required in a control microcontroller, including ROM, RAM, I/O ports, serial interfaces, comparator inputs, three-value inputs, timers and an interrupt system. These products differ from the earlier LC66358A series in their power supply voltage range and operating speed specifications.
