General Description
The Zatara^® ZA9L0 is a highly integrated system-on-
chip (SoC) microcontroller based on the ARM922T™
32-bit/16-bit core and tailored to the specific require-
ments of point-of-sale (POS) terminal design and meet
the strict security requirements of the Payment Card
Industry (PCI) Security Standards Council 2.0 specifica-
tion. 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 dif-
ferentiate 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 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 periph-
erals to support PIN pad applications, including an
LCD interface, multiple timers with PWM, watchdog,
and a 6-channel, 10-bit ADC.
