MFRC52302HN1

MFRC523 is a highly integrated the read/write device, which can realize the contactless communication when the 13.56 MHz. MFRC523 card reader support ISO/IEC 14443 A/MIFARE mode.

MFRC523 internal emitter no additional active circuit which can drive designed for and ISO/IEC 14443 A/MIFARE card and launch transponder communications and read/write antenna design. The receiver module provides a powerful and efficient demodulation and decoding circuit, can be used in the ISO/IEC 14443 a transponder signal/compatible MIFARE card and launch. Digital module management complete ISO/IEC 14443 A into the frame and error detection (parity and CRC) function.

Support all the ISO/IEC 14443 and ISO/IEC 14443 B protocol layer communications standards:

Correct installation oscillator, power supply, coil and other additional components

Correct deployment of ISO/IEC 14443-4 and/or standardized protocols such as ISO/IEC 14443 B protocol

Use up to the standard of ISO/IEC 14443 B the boon wisdom pu semiconductor devices may be infringement of the patent right for a third party.

PN533 support two-way transmission rate is as high as 848 kBd MIFARE higher baud rate contactless communication.

Provide the following host interface:

Serial peripheral interface (SPI)

RS232 serial UART (similar, voltage supply voltage level depends on the stitching)

I squared C bus interface

Characteristics and advantages

A highly integrated analog demodulation and decoding the response

Output buffer drives, can use at least external components to connect antenna

Support ISO/IEC 14443 A/MIFARE standard

Support ISO/IEC 14443 B read/write mode

Read/write mode of typical working distance up to 50 mm, depending on the antenna size and tuning

Read/write mode support MIFARE Mini, MIFARE 1 k and MIFARE 4 k encryption

Supports 212 kBd, 424 kBd and 848 kBd under ISO/IEC 14443 A high transfer rate of communication

Support MFIN/MFOUT

Additional internal power through the MFIN/MFOUT connected to the smart card IC

In support of the host interface

The fastest 10 MBPS of SPI
