DESCRIPTION

protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. The SN65HVD230, SN65HVD231, and SN65HVD232 controller area network (CAN) transceivers are designed for use with the Texas Instruments TMS320Lx240x 3.3-V DSPs with CAN controllers, or with equivalent devices. They are intended for use in standard. Each CAN transceiver is designed to provide differential transmit capability to the bus and differential receive capability to a CAN controller at speeds up to Mbps. Designed for operation in especially-harsh environments, these devices feature cross-wire protection, loss-of-ground and overvoltage protection, overtemperature protection, as well as wide common-mode range. The transceiver interfaces the single-ended CAN controller with the differential CAN bus found in industrial, building automation, and automotive applications. It operates over a -2-V to 7-V common-mode range on the bus, and it can withstand common-mode transients of On the SN65HVD230 and SN65HVD231, pin provides three different modes of operation: high-speed, slope control, and low-power modes. The high-speed mode of operation is selected by connecting pin to ground, allowing the transmitter output transistors to switch on and off as fast as possible with no limitation on the rise and fall slopes. The rise and fall slopes can be adjusted by connecting a resistor to ground at pin since the slope is proportional to the pin's output current. This slope control is implemented with external resistor values of k Ω to achieve a 15-V/ µ s slew rate, to 100 k Ω to achieve a 2-V/ µ s slew rate. See the Application Information section of this data sheet. The circuit of the SN65HVD230 enters a low-current standby mode during which the driver is switched off and the receiver remains active if a high logic level is applied to pin The DSP controller reverses this low-current standby mode when a dominant state (bus differential voltage 900 mV typical) occurs on the bus. The unique difference between the SN65HVD230 and the SN65HVD231 is that both the driver and the receiver are switched off in the SN65HVD231 when a high logic level is applied to pin and remain in this sleep mode until the circuit is reactivated by a low logic level on pin The V ref pin on the SN65HVD230 and SN65HVD231 is available as a V CC voltage reference. The SN65HVD232 is a basic CAN transceiver with no added options; pins and are NC, no connection.

www.ti.com APPLICATION INFORMATION INTRODUCTION TMS320Lx2403/6/7 3.3-V DSP ImplementationISO 11898 Specification Application Specific Layer Data-Link Layer Logic Link Control Medium Access Control Physical Layer Physical Signaling Physical Medium Attachment Medium Dependent Interface Embedded CAN Controller SN65HVD230 CAN Bus-Line APPLICATION OF THE SN65HVD230 SN65HVD230 SN65HVD231 SN65HVD232 SLOS346H MARCH 2001 REVISED JULY 2006 This application provides information concerning the implementation of the physical medium attachment layer in a CAN network according to the ISO 11898 standard. It presents a typical application circuit and test results, as well as discussions on slope control, total loop delay, and interoperability in 5-V systems. ISO 11898 is the international standard for high-speed serial communication using the controller area network (CAN) bus protocol. It supports multimaster operation, real-time control, programmable data rates up to Mbps, and powerful redundant error checking procedures that provide reliable data transmission. It is suited for networking intelligent devices as well as sensors and actuators within the rugged electrical environment of a machine chassis or factory floor. The SN65HVD230 family of 3.3-V CAN transceivers implement the lowest layers of the ISO/OSI reference model. This is the interface with the physical signaling output of the CAN controller of the Texas Instruments TMS320Lx240x 3.3-V DSPs, as illustrated in Figure Figure 31. The Layered ISO 11898 Standard Architecture The SN65HVD230 family of CAN transceivers are compatible with the ISO 11898 standard; this ensures interoperability with other standard-compliant products. Figure illustrates a typical application of the SN65HVD230 family. The output of a DSP's CAN controller is connected to the serial driver input, pin and receiver serial output, pin of the transceiver. The transceiver is then attached to the differential bus lines at pins CANH and CANL. Typically, the bus is a twisted pair of wires with a characteristic impedance of 120 Ω in the standard half-duplex multipoint topology of Figure Each end of the bus is terminated with 120- Ω resistors in compliance with the standard to minimize signal reflections on the bus.

Details of a Typical CAN Node Figure 33. Typical CAN Network The SN65HVD230/231/232 3.3-V CAN transceivers provide the interface between the 3.3-V TMS320Lx2403/6/7 CAN DSPs and the differential bus line, and are designed to transmit data at signaling rates up to Mbps as defined by the ISO 11898 standard. The SN65HVD230/231/232 are pin-compatible (but not functionally identical) with one another and, depending upon the application, may be used with identical circuit boards. These transceivers feature 3.3-V operation and standard compatibility with signaling rates up to Mbps, and also offer 16-kV HBM ESD protection on the bus pins, thermal shutdown protection, bus fault protection, and open-circuit receiver failsafe. The fail-safe design of the receiver assures a logic high at the receiver output if the bus wires become open circuited. If a high ambient operating environment temperature or excessive output current result in thermal shutdown, the bus pins become high impedance, while the D and R pins default to a logic high.

(continued) The bus pins are also maintained in a high-impedance state during low V CC conditions to ensure glitch-free power-up and power-down bus protection for hot-plugging applications. This high-impedance condition also means that an unpowered node does not disturb the bus. Transceivers without this feature usually have a very low output impedance. This results in a high current demand when the transceiver is unpowered, a condition that could affect the entire bus. R S (pin of the SN65HVD230 and SN65HVD231 provides for three different modes of operation: high-speed mode, slope-control mode, and low-power mode. The high-speed mode can be selected by applying a logic low to R S (pin 8). The high-speed mode of operation is commonly employed in industrial applications. High-speed allows the output to switch as fast as possible with no internal limitation on the output rise and fall slopes. The only limitations of the high-speed operation are cable length and radiated emission concerns, each of which is addressed by the slope control mode of operation. If the low-power standby mode is to be employed in the circuit, direct connection to a DSP output pin can be used to switch between a logic-low level for high speed operation, and the logic-high level 0.75 V CC for standby. Figure shows a typical DSP connection, and Figure shows the HVD230 driver output signal in high-speed mode on the CAN bus. Figure 34.

To reduce the electromagnetic interference generated by fast rise times and resulting harmonics, the rise and fall slopes of the SN65HVD230 and SN65HVD231 driver outputs can be adjusted by connecting a resistor from R S (pin to ground or to a logic low voltage, as shown in Figure The slope of the driver output signal is proportional to the pin's output current. This slope control is implemented with an external resistor value of k Ω to achieve a µ s slew rate, and up to 100 k Ω to achieve a 2.0 µ s slew rate as displayed in Figure Typical driver output waveforms from a pulse input signal with and without slope control are displayed in Figure A pulse input is used rather than NRZ data to clearly display the actual slew rate.

Typical SN65HVD230 250-kbps Output Pulse Waveforms With Slope Control If a logic high 0.75 V CC is applied to R S (pin in Figure and Figure the circuit of the SN65HVD230 enters a low-current, listen only standby mode, during which the driver is switched off and the receiver remains active. In this listen only state, the transceiver is completely passive to the bus. It makes no difference if a slope control resistor is in place as shown in Figure The DSP can reverse this low-power standby mode when the rising edge of a dominant state (bus differential voltage 900 mV typical) occurs on the bus. The DSP, sensing bus activity, reactivates the driver circuit by placing a logic low 1.2 on R S (pin 8). Occasionally, a runaway CAN controller unintentionally sends messages that completely tie up the bus (what is referred to in CAN jargon as a babbling idiot). When this occurs, the DSP can engage the listen-only standby mode to disengage the driver and release the bus, even when access to the CAN controller has been lost. When the driver circuit is deactivated, its outputs default to a high-impedance state. The unique difference between the SN65HVD230 and the SN65HVD231 is that both driver and receiver are switched off in the SN65HVD231 when a logic high is applied to R S (pin 8). The device remains in a very low power-sleep mode until the circuit is reactivated with a logic low applied to R S (pin 8). While in this sleep mode, the bus-pins are in a high-impedance state, while the D and R pins default to a logic high. Transceiver loop delay is a measure of the overall device propagation delay, consisting of the delay from the driver input to the differential outputs, plus the delay from the receiver inputs to its output. The loop delay of the transceiver displayed in Figure increases accordingly when slope control is being used. This increased loop delay means that the total bus length must be reduced to meet the CAN bit-timing requirements of the overall system. The loop delay becomes 100 ns when employing slope control with a Submit Documentation Feedback

Therefore, considering that the rule-of-thumb propagation delay of typical bus cable is ns/m, slope control with the 100-k Ω resistor decreases the allowable bus length by the difference between the 500-ns max loop delay and the loop delay with no slope control, 70.7 ns. This equates to (500-70.7 ns)/5 ns, or approximately m less bus length. This slew-rate/bus length trade-off to reduce electromagnetic interference to adjoining circuits from the bus can also be solved with a quality shielded bus cable. Figure 39. 70.7-ns Loop Delay Through the HVD230 With R S It is essential that the 3.3-V HVD230 family performs seamlessly with 5-V transceivers because of the large number of 5-V devices installed.
