ST21NFCC数据手册ST中文资料规格书

描述 Description

The ST21NFCC is a single chip designed for supporting 13.56 MHz contactless communication, including Near Field Communication (NFC) functions in Card Emulation mode.
This product is based on an advanced Smartcard ST21 microcontroller with 36 Kbytes of EEPROM.
The ST21NFCC is a serial access circuit based on a 8/16-bit CPU core. Operations are synchronized with an internally generated clock issued by the Clock Generator module.
Thanks to an enhanced power switch system, the ST21NFCC manages the power management of the device and its associated Secure Elements.
