DESCRIPTION

The

µPD72001-11 is an MPSC (Multi-Protocol Serial Controller) which is a general-purpose communication LSI

equipped with two sets of bidirectional parallel/serial converter circuits for data communication. This controller has

a transmitter function to convert the parallel data output by a data terminal into serial data and transmit this data to

a data transmission system such as a modem, and a receiver function to convert the serial data output by the data

transmission system into parallel data.

The MPSC can be used with data communications equipment with a variety of communication modes such as the

generally and widely used start-stop synchronization mode, and the HDLC mode which is used for high-speed

communication.

The

µPD72001-A8 is a low-voltage model.

FEATURES

• Two sets of parallel/serial circuits supporting three modes: start-stop synchronization, character synchronization,

and bit synchronization modes

→ Easy application to a system supporting two or more communication protocols such as a protocol converter or

ISDN terminal adapter

•

DPLL (Digital Phase Locked Loop), baud rate generator, and crystal oscillation circuit for transmission/reception

clock

→ Helps reduce cost by decreasing the number of external circuits

•

Many variations with power-saving features and small package size

→ Easy application to portable terminals and high-accuracy portable terminals

The features common to the

µPD72001-11 and 72001-A8 are explained as the features of the MPSC in this

document.
