Fujitsu MB85RC256V
The MB85RC256V is an FRAM (Ferroelectric Random Access Memory) chip in a configuration of 32,768 words × 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile memory cells. The read/write endurance of the nonvolatile memory cells used for the MB85RC256V has improved to be at least 1010 cycles, significantly outperforming other nonvolatile memory products in the number. The MB85RC256V does not need a polling sequence after writing to the memory such as the case of Flash memory or E2PROM.- Min Voltage : 2.7V
- Max Voltage : 5.5V
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C
