STMicroelectronics STEVAL-IPT002V1

Overview

STEVAL-IPT002V1 from STMicroelectronics is a smartcard interface demonstration board built around the ST8024 IC, designed for NDS conditional access systems in pay-TV set-top boxes. It supports 3 V or 5 V IC card supply (VDD/GND), integrates a DC-DC converter for VCC generation from 5 V ±20% input (VDDP/PGND), provides thermal and short-circuit protection on all card contacts, and meets ISO 7816, GSM11.11, and EMV standards.

For engineers reviewing the STEVAL-IPT002V1 datasheet, STEVAL-IPT002V1 pinout, STEVAL-IPT002V1 application, or STEVAL-IPT002V1 equivalent, this board enables rapid validation of smartcard power sequencing, contact protection, ESD robustness (>6 kV on card side), and NDS-compliant activation/deactivation protocols in secure embedded payment and conditional access hardware.

Technical Context

The board implements the full ST8024 smartcard interface controller, which handles clock generation, reset control, voltage regulation, and protocol-level card activation per ISO/IEC 7816-3. It decouples card power (VCC) from system supply via an integrated DC-DC converter, enabling independent 5 V input (VDDP) and isolated card-side ground (PGND).

All eight card contacts (C1–C8) feature dedicated thermal foldback and short-circuit current limiting, while card-side I/O lines include enhanced ESD protection exceeding 6 kV HBM. The board supports both 3 V and 5 V smartcards through configurable VDD selection and automatic voltage detection logic.

FAQ

What is the primary function of the STEVAL-IPT002V1 board?

The STEVAL-IPT002V1 is a demonstration board for the ST8024 smartcard interface IC, enabling hardware validation of ISO 7816-compliant smartcard power control, reset sequencing, contact protection, and NDS conditional access activation protocols in set-top box and payment terminal designs.

Does the board support both 3 V and 5 V smartcards?

Yes - the board provides jumper-selectable VDD configuration for either 3 V or 5 V smartcard operation, with automatic voltage detection and corresponding clock frequency scaling per ISO 7816-3 requirements.

How is card-side power isolation achieved?

Card-side VCC is generated by an onboard DC-DC converter powered separately from a 5 V ±20% input (VDDP/PGND), ensuring galvanic isolation between host system rails and the smartcard power domain.

What protection mechanisms are implemented on the card contacts?

All eight card contacts (C1–C8) incorporate real-time thermal foldback and short-circuit current limiting, plus >6 kV HBM ESD protection on card-side I/O lines - verified per IEC 61000-4-2 for reliability in field-deployed readers.
