ZA9L0000300ZABG - Zilog - Datasheet.Live

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.
