ST8034CQR

ST8034CQR is a 16-pin smartcard interface. This device is a complete low-cost analogue interface for asynchronous and synchronous smartcards operating at a supply voltage of 5V or 3V. It can be placed between the card and the microcontroller to provide all supply, protection, detection, and control functions, with just a few external components. It is used in applications such as set-top boxes, pay TV, identification, banking, and tachographs.

• Complete smartcard interface, ISO 7816 and EMV™ 4.3 payment systems compatible
• One protected half-duplex bidirectional buffered I/O line to the smartcard
• Card clock generation by integrated crystal oscillator or from external clock source
• Automatic card activation and deactivation sequences initiated by the microcontroller
• Non-inverted card reset pin RST driven by the RSTIN input
• Thermal and short-circuit protection of all card contacts
• Card presence detection contacts debounced, enhanced card side ESD protection of 8kV
• Supply current, logic (active mode) is 2mA maximum
• Input/output frequency is 1MHz maximum, delay time is 200ns maximum
• Operating temperature range from -25°C to +85°C, QFN16 package
