Next-generation self-driving cars will need advanced telematics to wirelessly exchange safety and operational data between vehicles and roadway infrastructure. Cars will need to communicate with one another to reduce collisions and optimize traffic flow (V2V). Cars will need to communicate with infrastructure to enable cloud-based map updates, real-time traffic management, automatic fare collection, and emergency vehicle access (V2I). For artificial intelligence, cars will need to communication with the cloud to get real time traffic information and software updates (V2C). Cars will need to communicate with pedestrians with smartphones/watches to prevent potential collisions (V2P). These systems are all handled in the communication module. Multichip Packages (MCPs) are essential to the communication modules in the systems handling those.
These next generation, autonomous communication modules require a small memory footprint, fast speeds and low power consumption. To meet these needs, Micron is investing in the next generation of SLC NAND based MCPs that will be stacked with LPDDR4 versus the current mainstream industry standard NAND MCP today that is stacked with LPDDR2.
The 70s/25nm SLC NAND inside is a new generation launched by Micron that now has 100k PE Cycling with 10yr data retention. The 100s/20nm LPDDR4 inside has ramped into high volume manufacturing earlier this year. Both the NAND and LPDDR4 are new additions to Micron’s Automotive solutions which puts the MCP’s, which combine these two technologies into one package, in a great position for stable support for many years to come.
These new LP4 based NAND MCPs, or MCP4’s, are well positioned to support the longevity and endurance requirements of both Industrial M2M applications as well Automotive Telematics, subsequently being offered in both AEC-Q100 Grade 3 (-40C to +85C) and AEC-Q100 Grade 2 (-40C to +105C). With its smaller footprint, packaging simplifications, faster speeds, and lower power consumption, this new MCP4 is the best value for your application.
