DESCRIPTION
M66014 Semiconductor Integrated Circuit is a serial bus con-
troller. It converts 2-byte parallel data that arrives from micro-
computer into serial and outputs it to serial bus. It also
converts serial data input from serial bus into parallel and out-
puts it to microcomputer.
The M66014 is used for the extension of microcomputer I/O
ports and two-way communication with peripheral equipment
connected with serial buses.
FEATURES
• Compatible with general-purpose 8-bit microprocessor bus-
ses
• TTL level input (one microcomputer side)
• Interrupt output
• Schmitt input (RESET, CS, SIN)
• Pin arrangement is fully compatible with M66011FP
• Low power dissipation
• Wide operating temperature range (Ta = –20 to 75˚C)
APPLICATION
Microcomputer I/O port extension, etc.
