Low-Cost 16-bit DSP with DDR Controller and 10/100 Mbps Ethernet MAC

• StarCore® SC1400 DSP extended core with one SC1400 DSP
   core, 256 Kbyte of internal SRAM M1 memory, 16 way 16 Kbyte
   instruction cache (ICache), four-entry write buffer, programmable
   interrupt controller (PIC), and low-power Wait and Stop
   processing modes.
• 192 Kbyte M2 memory for critical data and temporary data
   buffering.
• 8 Kbyte boot ROM.
• AHB-Lite crossbar switch that allows parallel data transfers
   between four master ports and six slave ports, where each port
   connects to an AHB-Lite bus; fixed or round robin priority
   programmable at each slave port; programmable bus parking at
   each slave port; low power mode.
• Internal PLL generates up to 300 MHz clock for the SC1400 core
   and up to 150 MHz for the crossbar switch, DMA channels, M2
   memory, and other peripherals.
• Clock synthesis module provides predivision of PLL input clock;
   independent clocking of the internal timers and DDR module;
   programmable operation in the SC1400 low power Stop mode;
   independent shutdown of different regions of the device.
• Enhanced 16-bit wide host interface (HDI16) provides a glueless
   connection to industry-standard microcomputers,
   microprocessors, and DSPs and can also operate with an 8-bit host
   data bus, making if fully compatible with the DSP56300 HI08
   from the external host side.
• DDR memory controller that supports byte enables for up to a
   32-bit data bus; glueless interface to 150 MHz 14-bit page mode
   DDR-RAM; 14-bit external address bus supporting up to 1 Gbyte;
   and 16-bit or 32-bit external data bus.
• Programmable memory interface with independent read buffers,
   programmable predictive read feature for each buffer, and a write
   buffer. (Continue ...)
