New 8GB LPDDR4X Device with On-Chip ECC for Automotive ADAS Systems and IoT Devices


Alliance Memory has announced a new LPDDR4X device featuring on-chip ECC and 8Gb AS4C256M32MD4V-062BAN which offers ~50% lower power ratings in the 200-ball FBGA package for higher power efficiency. The new 8Gb LPDDR4X device offers lower power consumption to increase battery life in portable electronics for the consumer, commercial, and industrial markets, including smartphones, smart speakers, and other IoT devices utilizing AI and 5G technologies. Moreover, it provides increased efficiency for advanced audio and ultra-high-resolution video in embedded applications.


This Device delivers fast clock speeds of 1.6GHz for extremely high transfer rates of 3.2Gbps. For automotive applications — including ADAS systems — the AEC-Q100 qualified device operates over a temperature range of -40°C to +105°C. Moreover, LPDDR4X SDRAM provides a reliable drop-in, pin-for-pin-compatible replacement for numerous similar solutions in high-bandwidth, high-performance memory system applications — eliminating the need for costly redesigns and part requalification.
