For engineers reviewing the ZA9L10D1NW2CSGA499 datasheet, ZA9L10D1NW2CSGA499 pinout, ZA9L10D1NW2CSGA499 application, or ZA9L10D1NW2CSGA499 equivalent, key selection criteria include PCI-compliant tamper detection, ISO 7816 smart card UART support, 3-track magnetic stripe reader interface, USB 2.0 OTG capability, and dual external bus architecture for SDRAM/Flash expansion.

Technical Context

The ZA9L10D1NW2CSGA499 implements an ARM922T core with MMU, enabling Linux® and Windows® Embedded CE OS support, and integrates dedicated security logic including voltage/temperature/frequency glitch monitors, active zeroization on tamper, and cryptographically verified boot via customer-unique keys stored in secure ROM.

It features a dual-bus external interface (primary + secondary) supporting synchronous Flash and SDRAM up to 512MB, alongside nine timer/counters with PWM, eight DMA channels, three UARTs (including two ISO 7816-compliant), and a 4-channel 10-bit ADC sampling at 45ksps - all optimized for PIN pad and EFTPOS system integration.

FAQ

What security certifications does the ZA9L10D1NW2CSGA499 support?

The ZA9L10D1NW2CSGA499 is designed to meet PCI Security Standards Council Payment Terminal Security (PTS) v2.0 requirements. It incorporates tamper-detection circuitry, secure boot with customer-unique keys, NIST 800-22–compliant RNG, and FIPS 180-2 SHA-1 - all essential for achieving PCI PTS certification. The ZA9L10D1NW2CSGA499 itself is not pre-certified; final validation occurs at the system level during terminal qualification.

Does the ZA9L10D1NW2CSGA499 include an integrated LCD controller?

Yes, the ZA9L10D1NW2CSGA499 includes a dedicated display controller interface supporting segment and dot-matrix LCDs common in POS terminals and PIN pads. It provides programmable bias, frame rate, and COM/SEG drive configuration - eliminating need for external LCD driver ICs in many designs.

Can the ZA9L10D1NW2CSGA499 operate without external SDRAM?

Yes, the ZA9L10D1NW2CSGA499 contains 64KB of embedded zero-wait-state SRAM sufficient for boot code and small RTOS applications. External SDRAM (up to 512MB) is optional and enabled only when running full Linux or complex payment stacks requiring larger memory footprint.

What is the purpose of the customer-unique key in the ZA9L10D1NW2CSGA499 secure boot ROM?

The ZA9L10D1NW2CSGA499 secure boot ROM uses a customer-unique cryptographic key to verify digital signatures on application firmware before loading. This ensures only authorized, unmodified code executes - preventing malware injection or counterfeit firmware. Keys are provisioned during manufacturing; each customer receives a distinct part number variant like ZA9L10D1NW2CSGA499.

How many independent ISO 7816 interfaces does the ZA9L10D1NW2CSGA499 support?

The ZA9L10D1NW2CSGA499 supports two fully independent ISO 7816 UARTs, each capable of T=0 and T=1 protocol operation. These are physically separate interfaces with dedicated clock, reset, and I/O pins - enabling concurrent use with two smart cards or SAM modules in multi-application terminals.

Is the ZA9L10D1NW2CSGA499 pin-compatible with other Zatara ZA9L1 variants?

Yes, all ZA9L1 family members including ZA9L10D1NW2CSGA499 share identical 256-ball LFBGA packaging and pinout. Differences between variants (e.g., ZA9L10D1NW2CSGA499 vs. ZA9L10D1NW2CSGA500) relate solely to programmed security keys and minor configuration fuses - not electrical or mechanical compatibility.
