Security functions are enabled and accelerated by the following hardware:
•
ARM TrustZone including the TZ architecture (separation of interrupts, memory
mapping, etc.)
•
SJC--System JTAG Controller. Protecting JTAG from debug port attacks by
regulating or blocking the access to the system debug features.
•
CAAM--Cryptographic Acceleration and Assurance Module, containing
cryptographic and hash engines, 16 KB secure RAM and True and Pseudo
Random Number Generator (NIST certified)
•
SNVS--Secure Non-Volatile Storage, including Secure Real Time Clock
•
CSU--Central Security Unit. Enhancement for the IC Identification Module (IIM).
Will be configured during boot and by eFUSEs and will determine the security
level operation mode as well as the TZ policy.
•
A-HAB Advanced High Assurance Boot--Hv4 with the new embedded
enhancements:SHA-256, 2048-bit RSA key, version control mechanism, warm
boot, CSU, and TZ initialization.

Expanded Chip Introduction
2.2.1
MT41K256M16HA-125:E
The board has 1GB of SDRAM (2x512MB). Micron’s MT41K256M16 is a 512MB DDR3
Synchronous DRAM, ideally suited for the main memory applications which require
large memory density and high bandwidth.
2.2.2
MMPF0100NPAEP
The PF0100 Power Management Integrated Circuit (PMIC) provides a highly
programmable/ configurable architecture, with fully integrated power devices and
minimal external components. With up to six buck converters, six linear regulators, RTC
supply, and coin-cell charger, the PF0100 can provide power for a complete system,
including applications processors, memory, and system peripherals, in a wide range of
applications. With on-chip One Time Programmable (OTP) memory, the PF0100 is
available in pre-programmed standard versions, or non-programmed to support
custom programming. The PF0100 is defined to power the entire embedded MCU
platform solution similar to i.MX6 based eReader, IPTV, medical monitoring and
home/factory automation.
2.2.3
AR8035
AR8035 is a single port 10/100/1000 Mbps tri-speed Ethernet PHY feaured with low
power and low cost. AR8035 supports MAC.TM RGMII interface and IEEE 802.3az-2010,
Energy Efficient Ethernet (EEE) standard through proprietary SmartEEE technology,
improving energy efficiency in systems using legacy MAC devices without 802.3az
