Benefits
Delivers high performance and functionality for improved
system performance
Allows for use of a protected memory OS
Helps to protect sensitive data using DES and AES block
cipher engines and MD5, SHA-1 and HMAC hash accelerators
Provides hardware acceleration of multiply instructions
improving overall system performance
Allows for use in typical DSP type applications
Increases system performance
Security circuitry to prevent unauthorized access to RAM
contents and increase system performance for critical code,
fast stack operations and Ethernet buffers
Allows the enable/disable of the clocks to most peripherals,
lowering power consumption
Minimizes power consumption for use in “green” products
Popular, economical and fast memory access which allows for
a scalable solution to meet power and performance needs
Enables control of an external hard disk
Enables fast integration of any PCI-based peripheral (ex.
Firewire, Bluetooth, WiFi, Graphics and DAQ systems, etc.)
Configurable as Full-Speed device, host or OTG
High-Speed capable with off-chip ULPI PHY
Enables remote access, remote management, redundant
networking or gateway functions
Provides full duplex asynchronous/synchronous receiver and
transmitter deriving an operating frequency from the internal
bus clock or external clock using the timer pin
Audio CODEC interface using I²S mode within SSI module
Allows full-duplex, asynchronous, NRZ serial communication
between MPU and remote devices
DMA SPI provides messaging automation and the scheduling
of messages
Also used for Serial Boot to SPI-based flash devices
I2C ports enable external interfaces to an LCD display,
EEPROM, A/D controller, etc. I2C provides high bandwidth
and ease of connectivity
Adds time of day and calendar functionality to system even
while main power is removed from MPU
Four 32-bit timers used independently or for generating DMA
transactions
Enables fast transfers of data with minimal processor
interaction
Allows four programmable periodic interrupts to system,
enabling system applications to have their own timer while
scheduler or OS has its own
Results in a large number of flexible I/O pins that allow
vendors to easily interface the device into their own designs
as every peripheral pin is GPIO capable
A fundamental debug functionality that defines the dynamic
instruction execution path
This allows the developers to use the same interface for
multiple platforms
Allows six breakpoints (4 PC, 1 address and 1 data) that can
be configured into 1 or 2 level trigger
