The C6743 device is a low-power digital signal processor based on C674x DSP core. The
device consumes significantly lower power than other members of the TMS320C6000™ platform of
DSPs.
The C6743 device enables original-equipment manufacturers (OEMs) and original-design
manufacturers (ODMs) to quickly bring to market devices featuring high processing
performance.
The C6743 DSP core uses a two-level cache-based architecture. The Level 1 program cache
(L1P) is a 32-KB direct mapped cache and the Level 1 data cache (L1D) is a 32-KB 2-way
set-associative cache. The Level 2 program cache (L2P) consists of a 128-KB of memory space that is
shared between program and data space. L2 memory can be configured as mapped memory, cache, or
combinations of the two.
The peripheral set includes: a 10/100 Mbps Ethernet MAC (EMAC) with a management data
input/output (MDIO) module; two I2C Bus interfaces; two multichannel
audio serial ports (McASPs) with 14/9 serializers and FIFO buffers; two 64-bit general-purpose
timers each configurable (one configurable as watchdog); up to 8 banks of 16 pins of
general-purpose input/output (GPIO) with programmable interrupt/event generation modes, multiplexed
with other peripherals; two 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 (EMIFs): an asynchronous
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
C6743 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 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.
