ZA9L1
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. The ZA9L1 provides a rich set
of 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, and
security panels. The Zatara ZA9L1 includes the essential
security 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 an
ADC, DMAs, UARTs, GPIOs, and timers that add flexibili-
ty to control and differentiate the system design.
System security is enhanced by a number of physical
and 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 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 ZA9L1 provides extensive communication support
with three UARTs, two independent SPI™ ports, a USB
2.0 On-The-Go (OTG) interface, and ample GPIO pins
to implement any communication interface. The ZA9L1
also has a targeted set of peripherals to support PIN
pad applications, including an LCD interface; multiple
timers 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.
