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.

Note: *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.

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 P-ch open drain. (In echo mode)

Applications

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