ST8024CDR

Specialized Overview

The ST8024CDR is a complete analog interface for asynchronous 3 V and 5 V smart cards, manufactured by STMicroelectronics. It operates with an integrated 26 MHz crystal oscillator and generates clock frequencies up to 20 MHz via division ratios of 1, 2, 4, or 8. The device provides a regulated card supply voltage (VCC) of 3 V or 5 V ± 5%, supporting currents up to 80 mA at input voltages between 4 V and 6.5 V. It handles current spikes up to 20 MHz and includes filtered overload detection at approximately 120 mA. The IC features enhanced ESD protection exceeding 6 kV on the card side and three protected half-duplex bidirectional buffered I/O lines.
