FM13UF02G FMSH GB/T29768-2013 Smart Card IC Wafer

The FMSH FM13UF02G is a security ic supporting GB/T29768-2013, supplied in wafer.

Key Specifications

Design Notes

• Contactless parts need a tuned antenna. Read range and current draw both depend on the coil geometry and the Q of the matching network, so treat the datasheet distance figure as a reference design value, not a guarantee.
• Where the part supports both contact and contactless operation, the two interfaces share the same die and power domain. Plan the supply so a contact transaction does not brown out the RF field.
• Check the card-side standard before selecting: ISO 14443 A and B differ at the air interface, and a reader built for one will not talk to cards of the other.
• EEPROM endurance and retention are specified per the datasheet. If the application rewrites counters frequently, budget the write cycles against card lifetime.

Common Questions

What standard does this chip support?

GB/T29768-2013. Matching the card-side standard is the first selection step — a reader built for one variant will not interoperate with cards of the other.

How is it connected to a host controller?

Through the host interface listed in the specifications above. The bus runs at pad voltage, so level shifting is not needed when the MCU shares the same rail.

Does it include the security algorithm in hardware?

Yes — the algorithm engine is on-die, which is why the key never leaves the chip.

What package is it available in?

wafer. The datasheet mechanical drawing gives the land pattern and the clearance needed around the antenna pins.
