CY15B104QN Overview
Functional description The EXCELON™ Auto CY15X104QN is an automotive grade, 4Mb non-volatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is non-volatile and performs reads and writes similar to a RAM. It provides reliable data retention for 151 years while eliminating the plexities, overhead, and system-level reliability problems caused by serial flash, EEPROM,...
