Extending its M24 serial EEPROM family, STMicroelectronics has announced four devices that are fully compatible with the industry-standard 4-ball Wafer Level Chip Scale Package (WLCSP) footprint. The additions enable, for the first time, two or more 4-pin EEPROMs to be connected to the same I2C bus with an individual I2C address hard-wired internally. This allows dedicated devices for specific purposes, such as front/rear camera modules, on the same bus.
The devices meet customers' needs for multiple sourcing by offering the same pitch, die orientation, and pin assignment as competitive products while allowing a choice of I2C slave addresses. The M24 serial EEPROMs maintain the unrivalled high-performance features of the existing devices, such as 4m erase/write cycles and 200 year data retention.
According to independent market analysts IHS, ST has been the world's number one EEPROM supplier for the past ten years, with a market share consistently above 25%. The M24 family, like all ST's EEPROM products, benefit from the Company's rigorous ‘automotive-grade’ approach in terms of robustness, quality and product longevity.
Samples of the 32- and 64kb M24C32-FCU6TP/TF, M24C32M-FCU6T/TF, M24C64-FCU6TP/TF and M24C64M-FCU6T/TF are available with prices starting from $0.14 in 1,000 unit quantities.
