LC66356B Datasheet Four-bit Single-chip Microcontrollers

Manufacturer: SANYO (now Panasonic)

Overview: 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, parator 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.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Key Features

  • and Functions.
  • ROM (with 4 K-, 6 K- and 8 K-byte capacities) and RAM (512 4-bit digits) on chip.
