A: If you are interested, you can contact us offline for communication.
178. After the subsequent NRAM technology matures, will it replace FRAM?
A: The storage capacity of NRAM will be relatively large and will not completely replace FRAM.
179. Can it be used in the aerospace and defense fields?
A: There are already applications in this area
. 180. What interface method does FRAM use, and what is the read and write speed?
A: FRAM currently has corresponding products for I2C SPI and parallel ports. The read and write speeds are very fast, which has great advantages over EEPROM and flash.
181. What are the requirements of FRAM for the operating environment
A: If the temperature is too high or too low, data may be lost. Please refer to the data sheet.
182. FRAM is said to be write-resistant. Are there any cases of write damage in current applications?
A: It mainly refers to the number of read and write times.
183. What are the requirements for working temperature and humidity
? A: Please refer to the data sheets of different chip products
. 184. There is a project at present. I don’t want to use the RTC plus battery method. Can FRAM be used to save the information before power failure ?
A: Yes
. 185. What kind of harsh environment or conditions are easy to damage FRAM?
A: If the temperature is too high or too low, data may be lost. Please refer to the data sheet.
186. FRAM has the power-off non-volatility of EEPROM, but does it have the storage speed of traditional RAM?
A: The storage speed of FRAM is the same as that of common RAM.
187. Is FRAM chip industrial grade? Does it support -40-85 degrees?
A: FRAM products are divided into industrial grade and automotive grade, which can support -40-85 degrees.
188. Can FRAM replace SPI NOR FLASH to store embedded boot programs?
A: FRAM can replace SPI NOR FLASH when the capacity is not very large.
189. What is the lowest operating temperature of FRAM (Ferroelectric Random Access Memory)? What is the read and write life under the lowest and highest temperature environments?
A: The current lowest operating temperature is -40 test degrees. The number of read and write times is not affected within the spec range.
190. Ask a sensitive question. Will this solution have entity list restrictions in the future?
A: It is currently speculated that it will not.
191. Is it possible for the code stored in the ferroelectric to be read and copied? Can it be used on the hardware of the copy board? How to prevent it from being stolen?
A: If FRAM is only used for storage, the data may be copied like other storage devices. A security mechanism can be used on the system to prevent plagiarism.
192. Can all memory be written at one time? That is to say, all storage space is written continuously after one instruction.
A: Chips without encryption algorithms only support one command to read and write 2Byte.
193. The instruction code of RFID is only one byte. Is there an extreme case where user data is mistaken for instruction code?
A: RFID instruction procedures are in accordance with international EPC standards. This situation will not occur if the correct process is followed.
