Designed for driver assistance and Level 3 (and above) autonomous driving, the MMIC (Monolithic Microwave Integrated Circuit) is a targeting radar, long-range forward radar and '4D' radar, "but can also be used for corner and center radar architectures processing, so-called 'satellite' automotive radar systems," according to the company.<\/p>\n
Dubbed the RAA270205, it has four transmit channels and four receive channels and supports up to 16 MIMO (multiple-input-multiple-output) operations, as well as cascading for more channels and better radar resolution.<\/p>\n

Inside the 7.6 x 5.6 mm ball grid array there is an ADC (112.5 Msamples\/s), a VCO (-97.5 dBn). \/Hz phase noise at 1 MHz), PLL (low noise -226 dBs), PA, LNA, 360\u00b0 phase shifters for beamforming accelerators and signal processing. Bandwidth up to 5 GHz is available.<\/p>\n
Specifications include 1.2W consumption (estimated 970mW at 40fps), 9dB noise figure, and 300MHz\/\u00b5s chip frequency.<\/p>\n
Among the safety mechanisms targeted to meet the functional safety requirements of ISO26262 are loopback chip testing, voltage monitors, clock monitors, and digital error checking.<\/p>\n
"It will fully meet automotive industry requirements such as IATF 16949, AEC -Q100 Grade2 and ASIL B," said Renesas, which plans product samples in the first quarter of next year.<\/p>\n<\/p>\n
