FAQ

What is the primary security certification target for ZA9L1033NW2CSGA429?

The ZA9L1033NW2CSGA429 is explicitly designed to meet Payment Card Industry (PCI) Security Standards Council 2.0 requirements for secure transaction devices. Its integrated tamper sensors, secure boot ROM with customer-unique keys, battery-backed secure SRAM, and active zeroization circuitry directly support PCI PTS and PCI PED validation. The device enables full compliance without external security co-processors.

Does ZA9L1033NW2CSGA429 support real-time operating systems or full Linux distributions?

Yes, the ZA9L1033NW2CSGA429 supports both real-time operating systems and full Linux distributions due to its ARM922T core with MMU, 8KB/8KB instruction/data caches, and 64KB zero-wait-state SRAM. The MMU enables virtual memory management required by Linux® and Windows® Embedded CE, while the JTAG-ICE interface facilitates robust debugging across OS layers.

How many independent smart card interfaces does ZA9L1033NW2CSGA429 provide?

The ZA9L1033NW2CSGA429 provides two fully independent ISO/IEC 7816-3 compliant UARTs, designated ISO7816A and ISO7816B. Each supports T=0 and T=1 protocols, separate clock generation, and independent power control - enabling simultaneous operation with two contact smart cards or secure application modules (SAMs) without shared resource contention.

What is the function of the 4KB secure SRAM in ZA9L1033NW2CSGA429?

The 4KB secure SRAM in ZA9L1033NW2CSGA429 is battery-backed and electrically isolated from main memory. It stores cryptographic keys, session tokens, and sensitive credentials. Upon detection of tampering (via voltage, temperature, frequency, or physical sensor inputs), the security controller triggers immediate zeroization - overwriting all contents with random data within microseconds to prevent extraction.

Is ZA9L1033NW2CSGA429 pin-compatible with other ZA9L1 variants?

Yes, all ZA9L1 family members including ZA9L1033NW2CSGA429 use the same 256-pin LFBGA package with 1.0mm ball pitch and identical mechanical footprint. However, functional pin mapping may differ between variants (e.g., ZA9L1033 vs. ZA9L1034) due to configuration options like USB OTG vs. USB host-only mode or different ISO 7816 channel allocations.
