M66014FP
16-bit Serial Bus Controller
Description
M66014 semiconductor integrated circuit is a serial bus controller. It converts 2-byte parallel data that arrives from
microcomputer into serial and outputs it to serial bus. It also converts serial data input from serial bus into parallel and
outputs 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 busses
• 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.

... M66014FP Serial Data Input/Output Operation A cycle of 16-bit serial output data setting and serial data communication starts with a write access given by microcomputer to transmission shift registers in M66014. M66014 has two 8-bit shift registers, on for upper byte (SR "L" to "H" after a write access is given to SR are output in series in this order. Output of each data starts from its most significant bit. At the CS rise edge, busy flag in M66014 is set, and OE output shifts from " ...
