DATA SHEET

MOS INTEGRATED CIRCUIT

µPD485505

LINE BUFFER

5K-WORD BY 8-BIT

Description

The µPD485505 is a 5,048 words by 8 bits high speed FIFO (First In First Out) line buffer. Its CMOS static circuitry

provides high speed access and low power consumption.

The µPD485505 can be used for one line delay and time axis conversion in high speed facsimile machines and

digital copiers.

Moreover, the µPD485505 can execute read and write operations independently on an asynchronous basis. Thus

the µPD485505 is suitable as a buffer for data transfer between units with different transfer rates and as a buffer for

the synchronization of multiple input signals. There are three versions, E, K, P, and L. This data sheet can be applied

to the version P and L. These versions operate with different specifications. Each version is identified with its lot

number (refer to 7. Example of Stamping).
