LC66354C, 66356C, 66358C
Four-Bit Single-Chip Microcontrollers with 4, 6, and 8 KB of On-Chip ROM
Preliminary Overview
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. • Evaluation LSIs — LC66599 (evaluation chip) + EVA85/800-TB6630X — LC66E308 (on-chip EPROM microcontroller) used together.
