Handheld mobile POS Machine or POS device

MK9221ECP3 POS Machine 1.CPU : ARM922T kernel processor 2.200MHz main frequency 3.support Linux system

Main feature:

Secure program loading mechanism ensure code real and effectiveDetective and tamper-proof mechanism protecting datas,such as  switches, protective nets,voltage,temperature,frequency etc.True random number generator4KB resettable NV SRAM is used to encrypt memory.10 channels against attack detect pin

Main component:

Model	Description
ZA9L1	256 pin,ARM922T kernel processor
CS8900	Ethernet controller
S29GL128N	16M bytes Nor Flash
MT48LC16M16A	32M bytes SDRAM

Description:

ZA9L1 is a highly integrated SoC micro-controller, base on ARM922T 32bit/16bit kernel.

This component strengthens system security through multi physical and logical protection mechanisms,which include environmental sensors(temperature,voltage,frequency),true hardware RNG,RTC,4KB safety of non-volatile SRAM memory, which is easily erased when tampered.

When connecting power, it is first to make authorization encrypted, then ensure attackers not to load the application program.
