Functional Description
The Excelon-Auto CY15X102QN is an automotive grade, 2-Mbit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes similar to a RAM. It provides reliable data retention for 121 years while eliminating the plexities, overhead, and system-level reliability problems caused by serial flash, EEPROM, and other nonvolatile memories. Unlike serial flash and EEPROM, the CY15X102QN performs write operations at bus speed. No write delays are incurred. Data is written to the memory array immediately after each byte is...
