Two microcontrollers from Renesas Technology America, the SH74552 and SH74562, are for advanced driver assistance system applications. They can process high-speed and fine-grained data from sensors for use in automobile active safety systems for obstacle detection and risk avoidance. The SH74552 and SH74562 32bit devices have a compact 13×13mm package, 160MHz high-speed operation, 1Mbyte of high-speed on-chip flash memory, and on-chip functions such as four-channel CAN. Both also have 256kbyte of on-chip SRAM for storing large amounts of data such as milliwave data or image data from cameras. Additionally, the SH74552 is equipped with a two-channel FlexRay controller. Sample shipments of products with a high operating frequency of 240 MHz have already begun to manufacturers of luxury cars. The two devices employ an FBGA package and are based on the company's existing 240MHz products but are in a mounting area approximately 42% smaller than the previous generation. Based on the earlier 240MHz products, the devices can reuse existing software resources to develop the driver assistance systems. Processing power is 288 MIPS at the maximum operating frequency of 160MHz.
