Can transceivers on 3.3V standard

Texas Instruments says it has released industry’s first family of 3.3V transmitter-receivers for the controller area network

Enabling lower power, cost and space savings for manufacturers of industrial and automotive control systems, Texas Instruments has released industry’s first family of 3.3V transmitter-receivers for the controller area network (CAN).

The HVD23x CAN family of transceivers reduces the need for an additional 5V power supply when used as bus interfaces for 3.3V micro-controllers and digital signal. Manufacturers of industrial and automotive control systems using Can bus will benefit from the lower power, space savings and reduced bill of materials made possible by this new family of devices.

Compliant with ISO 11898 – the Can bus architecture – the transceivers support differential signalling at speeds up to 1 Mbps, providing compatibility with existing signalling schemes. The devices are available in the industry-standard PCA82C250 footprint for double-terminated lines and half-duplex operation, saving time to market by providing a drop-in low-power replacement for existing components.

The first device to be available is the SN65HVD230, which features a programmable output transition time, or slew rate control, helping designers minimise EMI. The device also features an low-current standby mode to minimise power consumption while monitoring bus activity during idle periods.

Future devices, scheduled for release in the third quarter offer programmable slope control and a full-sleep mode to reduce power consumption even more. And released later this year will be a version without slew rate control, standby mode or sleep mode, offering greater cost-efficiency.
