ABRIDGED DATA SHEET Rev 0; 3/09 KIT ATION EVALU E L B A AVAIL Zatara High-Performance, Secure, 32-Bit ARM Microcontroller The Zatara® ZA9L0 is a highly integrated system-onchip (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 180MHz, the ZA9L0 is one of the fastest high-security microcontrollers available. The ZA9L0 provides a rich set of features on a single chip that reduces the manufacturing cost and time-to-market for secure transaction products such as POS terminals, vending machines, and security panels. The Zatara ZA9L0 includes the essential security features required of a POS terminal. It also provides seamless interfaces to LCD displays and keypads, and includes a wide array of peripherals such as an ADC, DMAs, UARTs, GPIOs, and timers that add flexibility to control and differentiate the system design. System security is enhanced by a number of physical and logical protection mechanisms including environmental sensors (temperature, voltage, and frequency), true hardware random-number generator (RNG), realtime clock (RTC), and 4KB of secure nonvolatile SRAM storage with fast erase capability upon tampering. On power-up, application code is first cryptographically verified for authenticity to ensure that attackers cannot insert their own application code. The ZA9L0 provides extensive communication support with three UARTs, two independent SPI™ ports, and ample GPIO pins to implement any communication interface. The ZA9L0 also has a targeted set of peripherals to support PIN pad applications, including an LCD interface, multiple timers with PWM, watchdog, and a 6-channel, 10-bit ADC.
