ISO/IEC 7816-3 Analog Front End

The ISO 7816-3 Analog Front End (AFE) is a mixed-signal IP including five fully integrated I/O pads intended for both interface device (reader) and Integrated Circuit Card (ICC).

特色

five fully-integrated I/O pads: CLK, RST, I/O, VCC and GND
fully compliant with the ISO/IEC 7816-3 standard (class A, B and C)
proven track record through mass production in 130 nm CMOS process
square pad with 80 µm x 80 µm opening
operating junction temperature range: -40°C to 125°C
CLK digital input pad: up to 50 MHz; internal pull-up; input noise rejection through optional filter and Schmitt trigger; standby mode; embedded level-shifters; power-up protection; silicon area smaller than 0.016 mm² in a 130 nm process
RST digital input pad: internal pull-up; input noise rejection through Schmitt trigger buffer; standby mode; embedded level-shifters; power-up protection; silicon area smaller than 0.016 mm² in a 130 nm process
I/O bidirectional digital pad: three output modes with optional slew-rate; internal pull-up; Schmitt triggers; standby mode; embedded level-shifters; power-up protection; independent control of Rx and Tx paths; silicon area smaller than 0.024 mm² in a 130 nm process
