New Delhi, March 13, 2015–Automotive-qualified serial EEPROMs from STMicroelectronics provide the industry’s largest selection of densities in the tiny 2mm x 3mm WFDFPN8 package, giving engineers maximum flexibility when designing highly integrated body controllers and gateways, as well as radar and camera modules for Advanced Driver Assistance Systems (ADAS).
Using a discrete serial EEPROM for data and parameter storagecan help simplify design while offering maximum upgrade flexibility. Limited memory package and density options have prevented taking full advantage of this approach in the most space-constrained applications, but ST is now offering its new automotive-qualified WFDFPN8 package at all densities from 2KB to 512KB. In addition, both I2C and SPI serial interfaces are supported.
The WFDFPN8 outline has already proved popular in consumer-electronics applications, and ST has now created a rugged version capable of withstanding automotive environments. The devices have passed AEC-Q100 grade 0reliability criteria tests and operate up to 125°C. Further advantages include 4ms write time allowing fast parameter storage; clock frequency up to 20MHz allowing rapid data exchanges; and built-in traceability and security features. These includea dedicated page for softwareidentification and a write-lockable page to keep sensitive data secure.
ST’s newest Automotive EEPROM devices are available immediately to fulfill sample or production orders. Budgetary pricing is from$0.156 for the 2KB M24C02-DRMF3TG/K with I2C interface, in quantities of 5000 units.
