Application note
CMOS F8H automotive EEPROM
cycling endurance and data retention
Introduction
The automotive applications require a very high level of reliability and robustness, each
single electronic device must therefore offer an ultra-high level of quality. In order to fulfill
these requirements, STMicroelectronics developed a new family of advanced automotive
EEPROM MXXxxx-A125/A145, based on a new improved architecture and produced with
the CMOS F8H automotive process.
This application note details the improved cycling and data retention performances of the
advanced automotive EEPROM MXXxxx-A125/A145 products, detailed in Table 1.
