Overview
The TCA5013ZAHR, produced by Texas Instruments, is a feature-rich smartcard interface IC designed for use in Point of Sale (POS) terminals and other secure access systems. This device supports up to 1 user card and 3 Secure Access Module (SAM) cards, ensuring compliance with EMV 4.3, ISO7816-3, and ISO7816-10 standards. It operates from a single supply voltage range of 2.7 V to 5.5 V and generates all necessary card voltages through an integrated DC-DC boost converter. The TCA5013ZAHR is controlled via a standard I2C interface and features multiple power-saving modes, including a low power shutdown mode and automatic card deactivation in case of faults.
