Renesas Technology has announced two 32-bit microcontrollers which will support advanced driver assistance systems including obstacle detection and risk avoidance in cars.
Significantly the MCUs are designed for use in mid and low price range vehicles.
Car makers are now looking for advanced driver assistance suitable not only for high-end vehicles but for lower priced vehicles.
Sample shipments will begin in May of products with a high operating frequency of 240MHz have already begun to manufacturers of luxury cars.
The SH74552 and SH74562 have processing performance and memory capacity necessary for high-speed and fine-grained processing of large volumes of data from sensors in applications such as obstacle detection and risk avoidance, and integrate on-chip peripheral functions such as CAN.
Both devices deliver high-speed operation, with processing performance of 288MIPS (million instructions per second) at the maximum operating frequency of 160MHz.
They have 1Mbyte of on-chip flash memory to accommodate the large software programs required by advanced driver assistance systems.
The MCUs also have 256kbyte of on-chip SRAM for storing large amounts of data such as radar 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, etc., is transferred via a controller area network (CAN) to a sensor fusion ECU, which uses it to perform control functions.
