M66011FP General Description

M66011 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 M66011 is used for the extension of microcomputer I/O ports and two-way communication with peripheral equipment connected with serial buses.

M66013FP General Description

The M66013FP is a semiconductor IC that is capable of performing serial-parallel conversion of data. This IC can set addresses.

The microcomputer uses the four signal lines of EN, CLK, DI and DO to send and receive data.

The IC adopts the two types of operation modes: echo-back mode and normal mode. In the echo-back mode, data received in serial can be sent to the sender within the same sequence (*1) as it is.

In the normal mode, restriction is given to the data to be sent to the sender. However, the normal mode supports the same communication protocol as that of the M66009FP. (*1): one of the higher order command bits is excluded.

Three bits in the echo-back mode and four bits in the normal mode are available for addresses. The echo-back mode and the normal mode have 8 types and 16 types of address, respectively, and any address can be set.

Receiving serial data from the microcomputer, the M66013 compares address data included in the data with an address entered in address setting. Only when these addresses match each other, a specified command provided are to be executed.

For serial input-parallel output operation, low order 8 bits of the received 16 bit serial data is converted to parallel data to output to pins D0 to D7. High order 8 bits are handled as address or command bits. Since the writing operation to the data register for parallel output and the outputting operation of register contents to pins D0 to D7 are performed with different commands and can be controlled independently, the register contents must be checked
before output of the specified data to pins D0 to D7.

For parallel input-serial output operation, parallel data of pins D0 to D7 are outputted to low order 8 bits of the sended 16 bit serial data. The contents of high order 8 bits of the sended 16 bit serial data differs in the using operation mode.

In echo mode, the I/O port output format is capable of setting to either N-ch or P-ch open drain. In normal mode, the I/O port output format is fixed to P-ch open drain.

M66013FP Features

• Is capable of providing high speed serial communication at 8 MHz.
• Provides two modes: echo back mode and normal mode.
• Is capable of reading serial input data in echo back mode.(However, 3 bits are available for the address.)
• Is capable of achieving communication protocol of current M66009FP in the normal mode. (However, 4 bits are available for the address.)
•Uses different commands in operations for output of data to I/O port: command for writing data into an output register and command for output operation to the I/O port.
• Provides an I/O port data read only command.
• Is capable of reading an output register.
• Adopts a decision by majority by reading three types of data when serial data is received.
• Is capable of setting the I/O port output format to either N-ch or Pch open drain. (In echo mode)

M66013FP Typical Application

Inter board communication in VTR, AV and OA equipment, expansion of microcomputer I/O port, etc.
