MCRF451 - Microchip Technology

MCRF451 13.56 MHz Read/Write Passive RFID Device

OF DEVICE FEATURES The MCRF450 needs an external LC resonant circuit connected between antenna A, antenna B and VSS pads. See Figure 2-2 for the external circuit configuration. The MCRF452 needs a single external antenna coil only between antenna A and VSS pads, as shown in Figure 2-4. This external circuit, along with the internal resonant capacitor, must b.
