Description
oscillator/clock inputs:
crystal oscillator input to the oscillator’s inverting amplifier
externally generated clock input; f
clk(ext)
= 13.56 MHz
interrupt request: generates an output signaling an interrupt event
ISO/IEC 14443 A MIFARE serial data interface input
serial data ISO/IEC 14443 A output
transmitter 1 modulated carrier output; 13.56 MHz
transmitter power supply for the TX1 and TX2 output stages
transmitter 2 modulated carrier output; 13.56 MHz
transmitter ground for the TX1 and TX2 output stages
not chip select input is used to select and activate the MFRC500’s microprocessor
interface
not write input generates the strobe signal for writing data to the MFRC500
registers when applied to pins D0 to D7
read not write input is used to switch between read or write cycles
not write input selects the read or write cycle to be performed
not read input generates the strobe signal for reading data from the MFRC500
registers when applied to pins D0 to D7
not data strobe input generates the strobe signal for the read and write cycles
not data strobe input generates the strobe signal for the read and write cycles
