MSC7116

Freescale Semiconductor Data Sheet Document Number: MSC7116 Rev. 11, 7/2007 MSC7116 Low-Cost 16-bit DSP with DDR Controller and 10/100 Mbps Ethernet MAC StarCore® SC1400 DSP extended core with one SC1400 DSP core, 192 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 www.DataSheet4U.com 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 266 MHz clock for the SC1400 core and up to 133 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 supp...
