General Description

The Zatara? ZA9L1 is a highly integrated system-on-chip (SoC) microcontroller based on the ARM922T? 32-bit/16-bit core and tailored to the specific requirements of point-of-sale (POS) terminal design and meet the strict security requirements of the Payment Card Industry (PCI) Security Standards Council 2.0 specification. Running at 200MHz, the ZA9L1 is one of the fastest high-security microcontrollers available.
