The SmarTool NFC main board includes an NXP PN532 transceiver for contactless communication; an NXP LPC11U37 microcontroller that supports full speed USB 2.0; a step down DC-DC converter; ultra-low jitter clock; and an LCD. The microcontroller is based around a 50MHz ARM Cortex-M0 core and features 128KB Flash memory and 12KB RAM.
The reference design is supplied with a set of ready-made application software that demonstrates the implementation of NFC technology in usage scenarios including access control and micropayment. Under access control the system interacts with mobile phone or an NFC tag and registers the presence of an enabled device. In the micropayment scenario the system simulates a vending machine and allows the loading of money and the dispensing of products. The software is compatible with devices using NXP MIFARE smartcard ICs including Classic, Ultralight and DESFire.
