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.

(a) When CR2A: D1, D0 = “0, 0” or “0, 1”
This pin functions as the DTRB output pin. The function of this pin is the same as the DTRA pin, except this
pin is used with channel B.
(b) When CR2A: D1, D0 = “1, 0”
This pin functions as the DRQRXB output pin. The function of this pin is the same as the DRQRxA pin, except
this pin is used with channel B.
(18) CTSA (Clear to Send A) and CTSB (Clear to Send B) ... Input
This pin is a general-purpose input pin and can be used to control a modem, etc. Changes in the status of this
pin affect the latching operation of the E/S bit. When E/S INT is enabled (CR1: D0 = “1”), the E/S interrupt is
generated.
If the Auto Enable mode (CR3: D5 = “1”) is set, the transmitter can be controlled by using the TX Enable bit (CR5:
D3) and this pin. This is illustrated in Table 1-3.

If the Auto Enable mode (CR3: D5 = “1”) is set, the receiver can be controlled by using the RX Enable bit (CR3:
D0) and this pin. This is illustrated in Table 1-4.
