Renesas Technology (distributed in Australia by Arrow Electronics) announced the SH74552 and SH74562 32-bit MCUs (microcontrollers) for advanced driver assistance system applications for automobile “active safety” systems, such as those that detect obstacles and avoid risks.

The MCUs are for advanced driver assistance system applications for automobile 'active safety' systems.

The devices, which come in a 13 mm x 13 mm package, include processing performance of 288 MIPS (million instructions per second) at the maximum operating frequency of 160 MHz, which enables them to process large volumes of data from things such as sensors very rapidly.

The Renesas devices have 1 MB of on-chip flash memory to accommodate the large software programs required by advanced driver assistance systems. They also have 256 KB of on-chip SRAM for storing large amounts of data such as milliwave data or image data from cameras.

In an advanced driver assistance system, data detected by a sensor electronic control unit (ECU) linked to milliwave radar, cameras is transferred via a controller area network (CAN) to a sensor fusion ECU, which uses it to perform control functions. The SH74552 and SH74562 integrate 4-channel CAN functionality to accommodate additional sensor or actuator ECUs for higher-performance advanced driver assistance systems.
