F-RAM™ for Automotive Markets
Every year, automobiles become more dependent on electronics. Systems that were once mechanical have moved to electronic control units (ECUs). New systems for automobile safety and user entertainment are introducing an increasing complexity and a greater need for resources.
Automotive Electronic Subsystem Overview
Automobile electronics are divided into independent, but connected, subsystems. Each subsystem is responsible for a specific task and can vary in scope and complexity from a simple radio control interface to a complex collision avoidance system. Nevertheless, these subsystems share some basic structures, for example, a microcontroller unit (MCU); a system bus interface in the form of CAN, OBD2, and in recent years Ethernet; input sensors; and output control logic. In addition, many subsystems need to store data instantly and continuously, which leads to performance and endurance design requirements—this is where Cypress’s Ferroelectric RAM (F-RAM) enters the picture.
