STMicroelectronics STEVAL-IPA001V1

Overview

STEVAL-IPA001V1 from STMicroelectronics is an anti-tamper and security evaluation kit based on the STM1403/STM1404 intrusion detection supervisors and uPSD3422EV microcontroller, designed for high-security modules in point-of-sale (POS) systems. It provides full voltage input/output monitoring, digital output supervision, and PWM control at 10 kHz for tamper event validation.

For engineers reviewing the STEVAL-IPA001V1 datasheet, STEVAL-IPA001V1 pinout, STEVAL-IPA001V1 application, or STEVAL-IPA001V1 equivalent, this board supports FIPS-140, EMV Co, ISO, ZKA, and Visa PED compliance verification, breadboard-level STM140x testing via QFN16-to-header daughter board, and real-time PFI/PFO/SAL signal analysis in secure embedded environments.

Technical Context

The kit implements dual-layer security supervision: the STM1404 monitors VCC, VBAT, VOUT, and PFI inputs while asserting SAL (Security Alert) and PFO (Power Fail Output) signals upon tamper detection; the uPSD3422EV handles firmware-based response logic, USB interface, and configurable threshold management via its 8051 core and flash memory.

Hardware-level tamper sensing includes dedicated analog input channels (Ai0–Ai7), precision voltage comparators (TS1852 dual op-amps), and isolated test points (TP1–TP4) for simultaneous monitoring of power rails, battery backup, and supervisor outputs under dynamic load and fault injection conditions.

FAQ

Is STEVAL-IPA001V1 still in production?

No - STEVAL-IPA001V1 is marked "Obsolete" in ST's official documentation (Rev 1, Nov 2007). It remains available through authorized legacy distributors and Aetrix Electronics' long-life inventory program for certified POS system maintenance and requalification projects.

Can the STM1404 on this board be replaced with STM1403?

Yes - the board supports both STM1403 and STM1404 per its description and schematic labeling. Pin compatibility is confirmed: both are 16-pin QFN devices sharing identical pinout, SAL/PFO/RSTn signaling, and analog input mapping (Ai0–Ai7), enabling direct substitution without layout change.

What USB functionality does uPSD3422EV provide on this board?

The uPSD3422EV integrates a full-speed USB 2.0 device controller with on-chip transceiver, supporting HID-class enumeration and custom firmware upload. It enables host PC communication for real-time tamper log retrieval, threshold reconfiguration, and SAL event timestamping without external PHY components.

Does this kit include software or firmware?

Yes - ST provided reference firmware for uPSD3422EV (including USB HID drivers and tamper response handlers) and configuration utilities in the original STEVAL-IPA001V1 package. Source code and project files are archived on ST's legacy support portal under document number CD001792.
