DESCRIPTION
• 0 to 10MHz data rate
The Philips Semiconductors SC68C562 Dual Universal Serial
• Programmable bit rate for each receiver and transmitter selectable
Communications Controller (CDUSCC) is a single-chip CMOS-LSI
communications device that provides two independent,
from:
– 19 fixed rates: 50 to 64k baud
multi-protocol, full-duplex receiver/transmitter channels in a single
package. It supports bit-oriented and character-oriented (byte count
and byte control) synchronous data link controls as well as
asynchronous protocols. The SC68C562 interfaces to the 68000
MPUs via asynchronous bus control signals and is capable of
program-polled, interrupt driven, block-move or DMA data transfers.
– One user-defined rate derived from programmable
counter/timer
– External 1X or 16X clock
– Digital phase-locked loop
• Parity and FCS (frame check sequence LRC or CRC) generation
The SC68C562 is hardware (pin) and software (Register)
compatible with SCN68562 (NMOS version). It will automatically
configure to NMOS DUSCC register map on power-up or reset.

• Programmable data encoding/decoding: NRZ, NRZI, FM0, FM1,
Manchester
The operating mode and data format of each channel can be
programmed independently. Each channel consists of a receiver, a
transmitter, a 16-bit multifunction counter/timer, a digital

phase-locked loop (DPLL), a parity/CRC generator and checker, and
associated control circuits. The two channels share a common bit
rate generator (BRG), operating directly from a crystal or an external
clock, which provides 16 common bit rates simultaneously. The
operating rate for the receiver and transmitter of each channel can
be independently selected from the BRG, the DPLL, the
• Programmable data transfer mode: polled, interrupt, DMA, wait

This makes the CDUSCC well suited for dual speed channel
applications. Data rates up to 10Mb/s are supported.
– Automatic frame termination on counter/timer terminal count or
DMA DONE
Each transmitter and each receiver is serviced by a 16 byte FIFO.
The receiver FIFO also stores 9 status bits for each character
received; the transmit FIFO is able to store transmitter commands
with each byte. This permits reading and writing of up to 16 bytes at
a time, thus minimizing the
• Transmit path clear status
• Interrupt capabilities
– Daisy chain option
– Vector output (fixed or modified by status)
– Programmable internal priorities
– Interrupt at any FIFO fill level
– Maskable interrupt conditions
potential for transmitter underrun, receiver overrun and reducing
interrupt or DMA overhead.
In addition, a flow control capability is provided to disable a remote
transmitter when the FIFO of the local receiving device is full. Two
modem control inputs (DCD and CTS) and three modem control
outputs (RTS and two general purpose) are provided. Because the
modem control inputs are general purpose in nature, they can be
optionally programmed for other functions. This document contains
the electrical specifications for the SC68C562. Refer to the CMOS
Dual Universal Serial Communications Controller (CDUSCC) User
Manual for a complete operational description of this product.

I/O
Bidirectional Data Bus: Active-high, 3-State. Bit 0 is the LSB and bit 7 is the MSB. All
data, command and status transfers between the CPU and the CDUSCC take place over
this bus. The data bus is enabled when CSN and R/WN or during interrupt acknowledge
cycles and single address DMA acknowledge cycles.

Read/Write: A high input indicates a read cycle and a low indicates a write cycle when
CEN is active.
Chip Select: Active-low input. When active, data transfers between the CPU and the
CDUSCC are enabled on D0–D7 as controlled by R/WN and A1–A6 inputs. When CSN is
high, the data lines are placed in the 3-State condition (except during interrupt
acknowledge cycles and single address DMA transfers).

Interrupt Request: Active-low, open-drain. This output is asserted upon occurrence of
any enabled interrupting condition. The CPU can read the general status register to
determine the interrupting condition(s), or can respond with an interrupt acknowledge cycle
to cause the CDUSCC to output an interrupt vector on the data bus.
IACKN
X1/CLK
Interrupt Acknowledge: Active-low. When IACKN is asserted, the CDUSCC responds
by either forcing the bus into high-impedance, placing a vector number, call instruction or
zero on the data bus. The vector number can be modified or unmodified by the status. If
no interrupt is pending, IACKN is ignored and the data bus placed in high-impedance.

I
Crystal or External Clock: When using the crystal oscillator, the crystal is connected
between pins X1 and X2. If a crystal is not used, an external clock is supplied at this input.
This clock is used to drive the internal bit rate generator, as an optional input to the
counter/timer or DPLL, and to provide other required clocking signals. When a crystal is
used, a capacitor must be connected from this pin to ground.
X2/IDCN

O
Crystal or Interrupt Daisy Chain: When a crystal is used as the timing source, the crystal
is connected between pins X1 and X2. This pin can be programmed to provide an
interrupt daisy chain active-low output which propagates the IACKN signal to lower priority
devices, if no active interrupt is pending. This pin should be left floating when an external
clock is used on X1 and X2 is not used as an interrupt daisy chain output. When a crystal
is used, a capacitor must be connected from this pin to ground.

Master Reset: Active-low. A low on this pin resets the transmitters and receivers and
resets the registers shown in Table 1 of the CDUSCC Users’ Guide. Reset is
asynchronous, i.e., no clock is required.

external receiver clock is specified for the channel, the input is sampled on the rising edge
of the clock.

Channel A (B) Transmitter Serial Data Output: The least significant bit is transmitted
first. This output is in the marking (high) condition when the transmitter is disabled or when
the channel is operating in local loopback mode. If external transmitter clock is specified
for the channel, the data is shifted on the falling edge of the clock.

(1X).
Channel A (B) Transmitter/Receiver Clock: As an input, it can supply the receiver,
transmitter, counter/timer, or DPLL clock. As an output, it can supply the counter/timer
output, the DPLL output, the transmitter shift clock (1X), the receiver sampling clock (1X),
the transmitter BRG clock (16X), The receiver BRG clock (16X), or the internal system
clock (X1 ÷ 2).

Channel A (B) Clear-to-Send Input or Loop Control Output: Active-low. The signal
can be programmed to act as an enable for the transmitter when not in loop mode. The
CDUSCC detects logic level transitions on this input and can be programmed to generate
an interrupt when a transition occurs. When operating in the BOP loop mode, this pin be-
comes a loop control output which is asserted and negated by CDUSCC commands. This
output provides the means of controlling external loop interface hardware to go on-line and
off-line without disturbing operation of the loop.

Channel A (B) Data Carrier Detected or External Sync Input: The function of this pin is
programmable. As a DCD active-low input, it acts as an enable for the receiver or can be
used as a general purpose input. For the DCD function, the CDUSCC detects logic level
transitions on this pin and can be programmed to generate an interrupt when a transition
occurs. As an active-low external sync input, it is used in COP mode to obtain character
synchronization for the receiver without receipt of a SYN character. This mode can be
used in disc or tape controller applications or for the optional byte timing lead in X.21.

Channel A (B) Receiver/Transmitter DMA Service Request or General Purpose
Output: Active-low. For half-duplex DMA operation, this output indicates to the DMA
controller that one or more characters are available in the receiver FIFO (when the
receiver is enabled) or that the transmit FIFO is not full (when the transmitter is enabled).
For full-duplex DMA operation, this output indicates to the DMA controller that data is
available in the receiver FIFO. In non-DMA mode, this pin is a general purpose output that
can be asserted and negated under program control.

DMA controller that the transmit FIFO is not full and can accept more data. When not in
full-duplex DMA mode, this pin can be programmed as a general purpose or a
Request-to-Send output, which can be asserted and negated under program control.
RTxDAKA/BN,
GPI1A/BN
Channel A (B) Receiver/Transmitter DMA Acknowledge or General Purpose Input:
Active-low. For half-duplex single address operation, this input indicates to the CDUSCC
that the DMA controller has acquired the bus and that the requested bus cycle (read
receiver FIFO when the receiver is enabled or load transmitter FIFO when the transmitter
is enabled) is beginning. For full-duplex single address DMA operation, this input indicates
to the CDUSCC that the DMA controller has acquired the bus and that the requested read
receiver FIFO bus cycle is beginning. Because the state of this input can be read under
program control, it can be used as a general purpose input when not in single address
DMA mode.

Channel A (B) Transmitter DMA Acknowledge or General Purpose Input: Active-low.
When the channel is programmed for full-duplex single address DMA operation, this input
is asserted to indicate to the CDUSCC that the DMA controller has acquired the bus and
that the requested load transmitter FIFO bus cycle is beginning. Because the state of this
input can be read under program control, it can be used as a general purpose input when
not in full-duplex single address DMA mode.

Done: Active-low, open-drain. DONEN can be used and is active in both DMA and
non-DMA modes. As an input, DONEN indicates the last DMA transfer cycle to the
TxFIFO. As an output, DONEN indicates either the last DMA transfer from the RxFIFO or
that the transmitted character count has reached terminal count.
RTSA/BN,
SYNOUTA/BN
Channel A (B) Sync Detect or Request-to-Send: Active-low. If programmed as a sync
output, it is asserted one bit time after the specified sync character (COP or BISYNC
modes) or a FLAG (BOP modes) is detected by the receiver. As a Request-to-Send
modem control signal, it functions as described previously for the TxDRQN/RTSN pin.
DTACKN
O
Data Transfer Acknowledge: Active-low, 3-state. DTACKN is asserted on a write cycle to
indicate that the data on the bus has been latched, and on a read cycle or interrupt
acknowledge cycle to indicate valid data is on the bus. In a write bus cycle, input data is
latched by the assertion (falling edge) of DTACKN or by the negation (rising edge) of CSN,
whichever occurs first. The signal is negated when completion of the cycle is indicated by
negation of CSN or IACKN input, and returns to the inactive state (3-state) a short period
after it is negated. In single address DMA mode, input data is latched by the assertion
(falling edge) of DTCN or by the negation (rising edge) of the DMA acknowledge input,
whichever occurs first. DTACK is negated when completion of the cycle is indicated by the
assertion of DTCN or negation of DMA acknowledge inputs (whichever occurs first), and
returns to the inactive state (3-state) a short period after it is negated. When inactive,
DTACKN requires an external pull-up resistor.

NOTES:
1. Stresses above those listed under Abs. Max Ratings may cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in the operation section of this specification is not implied.
2. Clock may be stopped (DC) for testing purposes or when the CDUSCC is in non-operational modes. Operation down to 0 rate clocks is
implied by a full static CMOS design, but is not verified in testing or characterization.
3. This product includes circuitry specifically designed for the protection of its internal devices from damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying any voltages larger than the rated maxima.
4. Parameters are valid over specified temperature and voltage range.
5. All voltage measurements are referenced to ground (GND). For testing, all inputs except X1/CLK swing between 0.2V and 3.0V with a transi-
tion time of 20ns maximum. For X1/CLK, this swing is between 0.2V and 4.4V. All time measurements are referenced at input voltages of
0.2V and 3.0V and output voltages of 0.8V and 2.0V, as appropriate.
6. See Figure 18 for test conditions for outputs.
7. Tests for open drain outputs are intended to guarantee switching of the output transistor. To include noise margin this response is measured
from the switching signal midpoint to 0.2 V above the required output level.
8. Execution of the valid command (after it is latched) requires a minimum of three rising edges of X1 (see Figure 19).
9. These values were no explicitly tested; they are guaranteed by design and characterization data.
10.X1/CLK and X2 are not tested with a crystal installed.
11. X1/CLK frequency must be at least as fast as the faster of the receiver or transmitter data rate.
12.The X1 clock drives DTACKN, Baud Rate Generator, command register and the update of the FIFO fill level encoders. The Command
Register requires three X1 clocks between two commands; FIFO fill level encoding requires 2.5 to 3.5 X1 cycles.
13.The 68562 bus interface may be operated in two modes; a 68000 compatible mode with automatic DTACK generation and a short chip
select mode. DTACKN should not be used externally in the short chip select mode. The DTACKN signal is generated by the assertion of
the chip select, and data is latched by assertion of DTACKN or by de-assertion of the chip select, whichever comes first. In single address
DMA, the DTACK signal will be de-asserted by the assertion of the DTCN or from the de-assertion of the TxDAKN, whichever occurs first.
14.Also includes X2/IDCN pin in IDC mode.
15.In case of 3-state output, output levels V + 0.2 are considered float or high impedance.
