ZA9L1043NW2CSGA427 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 requirementsof point-of-sale (POS) terminal design and meet the strictsecurity requirements of the Payment Card Industry (PCI)Security Standards Council 2.0 specification. Running at200MHz, the ZA9L1 is one of the fastest high-securitymicrocontrollers available. The ZA9L1 provides a rich setof features on a single chip that reduces the manufactur-ing cost and time-to-market for secure transaction prod-ucts such as POS terminals, vending machines, andsecurity panels. The Zatara ZA9L1 includes the essentialsecurity features required of a POS terminal. It also pro-vides seamless interfaces to LCD displays and keypads,and includes a wide array of peripherals such as anADC, DMAs, UARTs, GPIOs, and timers that add flexibili-ty to control and differentiate the system design.System security is enhanced by a number of physicaland logical protection mechanisms including environ-mental sensors (temperature, voltage, and frequency),true hardware random-number generator (RNG), real-time clock (RTC), and 4KB of secure nonvolatile SRAMstorage with fast erase capability upon tampering. Onpower-up, application code is first cryptographicallyverified for authenticity to ensure that attackers cannotinsert their own application code.The ZA9L1 provides extensive communication supportwith three UARTs, two independent SPI™ ports, a USB2.0 On-The-Go (OTG) interface, and ample GPIO pinsto implement any communication interface. The ZA9L1also has a targeted set of peripherals to support PINpad applications, including an LCD interface; multipletimers with PWM; a watchdog; a 4-channel, 10-bit ADC;two ISO 7816 smart card UARTs; and a 3-track mag-netic stripe reader interface.EFTPOSPIN PadsEPP
