SLOS346G – MARCH 2001 – REVISED JUNE 2002
DESCRIPTION
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 applications employing the CAN serial communication physical layer in
accordance with the ISO 11898 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 1 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 ±25 V.
On the SN65HVD230 and SN65HVD231, pin 8 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 8 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 8, since the
slope is proportional to the pin’s output current. This slope control is implemented with external resistor values
of 10 kΩ, to achieve a 15-V/µs slew rate, to 100 kΩ, to achieve a 2-V/µs 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 8. 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 8 and remain in this sleep mode
until the circuit is reactivated by a low logic level on pin 8.
The Vref pin 5 on the SN65HVD230 and SN65HVD231 is available as a VCC/2 voltage reference.
The SN65HVD232 is a basic CAN transceiver with no added options; pins 5 and 8 are NC, no connection.
