The TDA8020HL is a one-chip dual smart card interface. Controlled by the I2C-bus, it guarantees conformity to ISO 7816 or EMV2000 with very few external components.
The TDA8020HL is a single‑chip dual smart‑card interface that provides two independent 6‑contact smart‑card connections. It includes an integrated DC‑to‑DC converter, voltage supervisor, and I²C‑bus control, allowing operation with supply voltages from 2.7 V to 6.5 V and minimal external components.
The document details functional blocks, pin assignments, electrical specifications, and the I²C‑bus protocol used for configuration and status monitoring. It also lists ordering information and contact details for Philips Semiconductors.
