CY327 | System basis IC for engine or transmission control units

System supply and communication interfaces combined in one chip

Suitable for many microcontrollers. Switched mode μC core supply, adjustable from 0.9V to 1.525V.

A configurable pre-regulator keeps the ECU running until as low as 3V. A switched mode buck converter for the microcontroller core reduces the power dissipation of your ECU by up to 4W.

Benefits

Integrated CAN and LIN interface

VDA E-gas compliant

3 level Watchdog for VDA 2.0 compliance
