GXSC GX85RS2MC (MB85RS2MT) in Public Transportation IC Card Application

IC card is a microelectronic chip embedded in the card base in line with ISO7816 standards, made in the form of cards, IC card chip has the ability to write data and store data, IC card memory content according to the need to be conditional for external reading, completed for internal information processing and determination of the use of the card, has been very widely used in many fields, including finance, transportation, social security and so on. Therefore, the IC card not only has a large storage capacity, but also has a strong security, which can ensure the safety of reading and writing the data stored on the card, and can carry out the authentication of the user‘s identity.

The use of GXSC ferroelectric memory GX85RS2MC in public transportation IC cards can utilize the ferroelectric effect of ferroelectric crystals to achieve data storage. Since the ferroelectric effect is the inherent polarization polarization characteristic of ferroelectric crystals and has nothing to do with electromagnetic action, the contents of the public transport IC card will not be affected by external magnetic fields and other factors, and the GX85RS2MC has non-volatile storage characteristics. GX85RS2MC has non-volatile storage characteristics, which makes it easier and safer to record the history of card usage and store the information used for it.

Data retention: Since the GX85RS2MC ferroelectric memory does not require a voltage to hold data and does not need to be refreshed periodically like DRAM, the durability of the GX85RS2MC (10 years @ 85°C; 200 years @ 25°C) makes it possible to keep the data in memory for a long period of time even when the public transportation IC card is not in use.

Low Power Consumption: GX85RS2MC ferroelectric memory has extremely low power consumption for reading and writing, it operates with a voltage range of 2.7V to 3.6V, and the minimum standby power consumption is only 9 microamps, which can instantly save the data under low current, which makes the use of public transportation IC card more energy-saving and environmentally friendly.
