CY329 | System basis IC for engine control units

Flexible and balanced power concept to reduce hot spots on PCB

System supply, power stages and CAN phy combined in one chip.

CY329 is a high-end system basis IC with power stages for powertrain control units. A configurable pre-regulator keeps the ECU running down to 3V battery voltage. A system supply wakeup process can be configured for most efficient start. The switched mode buck converter for the microcontroller core voltage reduces power dissipation significantly. It communicates using micro second channel (MSC) interface.

Benefits

Integrated CAN-FD physical layer

Power stages with integrated clamping and diagnosis

3 level Watchdog for VDA 2.0 compliance
