产品介绍 73S8024RNFEATURES
• Card Interface: Complies with ISO-7816-3, EMV 4.0 and NDS A LDO voltage regulator provides 3V / 5V to the card from an external power supply input Provides at least 90mA to the card ISO-7816-3 Activation / Deactivation sequencer with emergency automated deactivation on card removal or fault detected by the protection circuitry Protection includes 3 voltage supervisors that detect voltage drops on VCC (card), VDD (digital)**, and VPC (regulator) power supplies The VDD voltage supervisor threshold value can be externally adjusted** Over-current detection 150mA max Card clock stop high or low* 2 card detection inputs, 1 for each possible user polarity Auxiliary I/O lines, for C4 / C8 contact signals* Card CLK clock frequency up to 20MHz • System Controller Interface: 3 Digital inputs control the card activation / deactivation, card reset and card voltage 4 Digital inputs control the card clock (division rate and card clock stop modes) 1 Digital output, interrupt to the system controller, allows the system controller to monitor the card presence and faults. Crystal oscillator or host clock, up to 27MHz • Regulator Power Supply: 4.75V to 5.5V (EMV 4.0) 4.85V to 5.5V (NDS) • Digital Interfacing: 2.7V to 5.5V • 6kV ESD Protection on the card interface • Package: SO28, 20QFN or 32QFN |
