CMOS Dual universal serial communications controller (CDUSCC)

DESCRIPTION

The Philips Semiconductors SC68C562 Dual Universal Serial Communications Controller (CDUSCC) is a single-chip CMOS-LSI communications device that provides two independent, 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.

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.

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 counter/timer, or from an external 1X or 16X clock.

This makes the CDUSCC well suited for dual speed channel applications. Data rates up to 10Mb/s are supported.

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

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.

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.

34, 15 37, 17 O 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.

33, 16 36, 18 O Channel A (B) Transmitter DMA Service Request, General Purpose Output, or

Request-to-Send: Active-low. For full-duplex DMA operation, this output indicates to the 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.

44, 5 48, 5 I 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.

35, 14 38, 16 I 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.

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.

41, 8 45, 9 O 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.

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 transition time of 20ns maximum. For X1/CLK, this swing is between 0.2V and 4.4V . All time measurements are referenced at input volta ges 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.
