1.3 Description
The device is a low-power ARM microprocessor based on an ARM926EJ-S.
The device enables original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs)
to quickly bring to market devices featuring robust operating systems support, rich user interfaces, and
high processing performance life through the maximum flexibility of a fully integrated mixed processor
solution.
The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and
processes 32-bit, 16-bit, or 8-bit data. The core uses pipelining so that all parts of the processor and
memory system can operate continuously.
The ARM core has a coprocessor 15 (CP15), protection module, and data and program memory
management units (MMUs) with table look-aside buffers. The ARM core has separate 16KB of instruction
and 16-KB data caches. Both memory blocks are four-way associative with virtual index virtual tag (VIVT).
The ARM core also has 8KB of RAM (Vector Table) and 64KB of ROM.
The peripheral set includes: a 10/100 Mbps Ethernet MAC (EMAC) with a management data input/output
(MDIO) module; two I²C Bus interfaces; 3 multichannel audio serial port (McASP) with 16/12/4 serializers
and FIFO buffers; two 64-bit general-purpose timers each configurable (one configurable as watchdog); a
configurable 16-bit host-port interface (HPI); up to 8 banks of 16 pins of general-purpose input/output
(GPIO) with programmable interrupt/event generation modes, multiplexed with other peripherals; three
UART interfaces (one with both RTS and CTS); three enhanced high-resolution pulse width modulator
(eHRPWM) peripherals; three 32-bit enhanced capture (eCAP) module peripherals which can be
configured as 3 capture inputs or 3 auxiliary pulse width modulator (APWM) outputs; two 32-bit enhanced
quadrature encoded pulse (eQEP) peripherals; and 2 external memory interfaces: an asynchronous and
SDRAM external memory interface (EMIFA) for slower memories or peripherals, and a higher speed
memory interface (EMIFB) for SDRAM.
The Ethernet Media Access Controller (EMAC) provides an efficient interface between the device and the
network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbps and 100 Mbps in either half-
or full-duplex mode. Additionally, an MDIO interface is available for PHY configuration.
The HPI, I²C, SPI, USB1.1, and USB2.0 ports allow the device to easily control peripheral devices and/or
communicate with host processors.
The rich peripheral set provides the ability to control external peripheral devices and communicate with
external processors. For details on each of the peripherals, see the related sections later in this document
and the associated peripheral reference guides.
The device has a complete set of development tools for the ARM processor. These include C compilers
and a Windows® debugger interface for visibility into source code execution.
