New Application Note Differences in FM24Cxx and FM24CxxA There are differences between “A” and “non-A” two-wire 4Kb and 16Kb FRAM devices. The FM24C04 and FM24C16 memory devices operate up to 400kHz, whereas the FM24C04A and FM24C16A operate at speeds up to 1MHz. There is also a functional difference between A and non-A parts, which involves the write protect pin WP. The original non-A parts protect the upper half of the memory array when WP is high. The new A parts protect the entire memory array when WP is high. Lastly, the A devices implement an internal pulldown on the WP pin. |
Just Posted Available NOW! Serial FRAM rivals existing parallel nonvolatile RAM solutions The FM25L256 is a 256-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or FRAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 10 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. |
