ZA9L1000300ZEMG - Maxim Integrated

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 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.
