Cost-Efficient 16-Bit DSP with DDR Controller and 10/100 Mbps Ethernet MAC

The MSC7119 device is a member of the NXP^® MSC711x family, a high-performance, cost-effective family of DSPs based on the StarCore^® ™ SC1400 core that offers system solutions, flexibility with peripherals and performance, and overall system cost savings. Devices in the MSC711x family target high-bandwidth highly computational DSP applications and are optimized for packet telephony applications, providing a competitive price per channel for voice over packet systems. The MSC7119 is a highly integrated DSP that contains the SC1400 core, on-chip emulation logic, 448 KB of SRAM memory, 16 KB ICache, 8 KB boot ROM, an 8 KB trace buffer, a 32-channel DMA controller, a 4-layer crossbar switch, a DDR memory controller, two 128-channel time-division multiplexing (TDM) interfaces with hardware support for m/A-law decoding/encoding, a UART, a 16-bit host interface (HDI16) to support an external host processor, a programmable interrupt controller (PIC), a 10/10Base-T MII/RMII, an I2C interface, eight timers, GPIOs, and a JTAG port. The SC1400 core has four ALUs and performs at 1200 DSP million multiply-accumulates per second (MMACS) with an internal 300 MHz clock at 1.2 V.
