Giới thiệu Bảng Mạch Phát Triển Nfc / Pn532 / Rfid tại Lotte Market

Overview

Pn 532 is a highly integrated non-contact read-and-write chip that contains the 80c51 microcontroller kernel and integrates various active/passive non-contact communication methods and protocols under 13.56 mhz.

The pn532 transmission module supports 6 different working modes:
Read-and-write mode, supporting iso/iec 14443a/mifare?Mechanisms
Read-and-write mode, supporting the felica mechanism
Read-and-write mode, supporting iso/iec 14443b mechanism
Card operating mode, supporting iso 14443 a/mifare?Mechanisms
Card operating mode, felica mechanism
Iso/iec18092, ecm340 point-to-point
Characteristics of pn532
80c51 microcontroller kernel with 40 kb rom and 1 kb ram
Highly integrated analog circuits, demodulation and decoding responses
Output buffer drives connect antennas through the smallest number of external passive devices
Integrated rf field detector
Integrated data mode detector
Supporting iso/iec 14443 a/mifare?
Iso/iec 14443b supported only in the reader mode
Typical operating distance in the reader mode is more than 50 mm, specific distance determined by antenna size, tuning, and power supply
Operating distance of up to 50 mm in nfcip-1 mode, depending on the size of the antenna, tuning and power supply
Typical operating distance in card mode is about 100 mm, depending on antenna size, tuning and external field strength
In the reader mode, support mifare classic encryption, can support 212 kbit/s and 424 kbit/s two higher data transmission speeds
Felica model, communications wave rates in support of 106kbit/s, 212kbit/s and 424kbit/s
