µPD72001-11, 72001-A8
MULTI-PROTOCOL SERIAL CONTROLLERS
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.
For this product, the following documents are separately available. Read these documents as well as this Data
Sheet.
• User’s Manual (S12472E)
(I) (S12753E)
• Application Notes (II) (On preparation)
(III) (On preparation)
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.
The information in this document is subject to change without notice.
