Description

The C6745/6747 is a Low-power applications processor based on C674x™ DSP core. It provides significantly lower power than other members of the TMS320C6000™ platform of DSPs.

The C6745/6747 enables OEMs and ODMs to quickly bring to market devices featuring high processing performance.

The C6745/6747 DSP core uses a two-level cache-based architecture. The Level 1 program cache (L1P) is a 32KB direct mapped cache and the Level 1 data cache (L1D) is a 32KB 2-way set-associative cache. The Level 2 program cache (L2P) consists of a 256KB memory space that is shared between program and data space. L2 also has a 1024KB ROM. L2 memory can be configured as mapped memory, cache, or combinations of the two. Although the DSP L2 is accessible by other hosts in the system, an additional 128KB RAM shared memory (C6747 only) is available for use by other hosts without affecting DSP performance.

The peripheral set includes: a 10/100 Mb/s Ethernet MAC (EMAC) with a Management Data Input/Output (MDIO) module; two inter-integrated circuit (I2C) Bus interfaces; 3 multichannel audio serial port (McASP) with 16/9 serializers and FIFO buffers; 2 64-bit general-purpose timers each configurable (one configurable as watchdog); a configurable 16-bit host port interface (HPI)[C6747 only]; up to 8 banks of 16 pins of general-purpose input/output (GPIO) with programmable interrupt/event generation modes, multiplexed with other peripherals; 3 UART interfaces (one with RTS and CTS); 3 enhanced high-resolution pulse width modulator (eHRPWM) peripherals; 3 32-bit enhanced capture (eCAP) module peripherals which can be configured as 3 capture inputs or 3 auxiliary pulse width modulator (APWM) outputs; 2 32-bit enhanced quadrature 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 C6745/6747 and the network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex mode. Additionally an Management Data Input/Output (MDIO) interface is available for PHY configuration.

The HPI, I2C, SPI, USB1.1 and USB2.0 ports allow the C6745/6747 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.
