Automotive NFC Key Drivers 13

A NFC Keycard with cryptography costs <<1$

A Keyfob replacement costs 120~800$

=> considerable cost reduction also for initial

production costs on both car & key side.

Key cost reduction

Automotive Requirements 22

Large operating volumeST25R3914/15 offers highest output power combined with automatic antenna tuning.

Low power consumption

ST25R3914/15 offers low power wakeup functionality combining inductive sensors.

Wide Interoperability

ST25R3914/15 offers excellent P2P compatibility with NFC devices

EMC performance

Benefits in Automotive

• No external Booster required for required performance

• ST25R3914/15 offers by far the highest output power of all readers on the market. No additional

booster circuitry is required. This is critical with small antennas and metal environment

• Programmable Low power wakeup

• Optimized for operation in battery mode

• Automatic antenna tuning

• Reader is independent on placement. Influence of multiple objects (tags or others) is minimized

• Higher efficiency / less power consumption

• Fastest time to market (Dynamic Power adjustment, Automatic Gain Control, Squelch Feature)

• ST25R3914/15 reduced time to market at our customers significantly vs. competitor solutions
