1 / 60 page  Freescale Semiconductor Data Sheet Document Number: MSC7119 Rev. 8, 4/2008 © Freescale Semiconductor, Inc., 2004, 2008. All rights reserved. MSC7119 MAP-BGA–400 17 mm × 17 mm •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. • System control unit performs software watchdog timer function; includes programmable bus time-out monitors on AHB-Lite slave buses; includes bus error detection and programmable time-out monitors on AHB-Lite master buses; and has address out-of-range detection on each crossbar switch buses. • Event port collects and counts important signal events including DMA and interrupt requests and trigger events such as interrupts, breakpoints, DMA transfers, or wake-up events; units operate independently, in sequence, or triggered externally; can be used standalone or with the OCE10. • Multi-channel DMA controller with 32 time-multiplexed unidirectional channels, priority-based time-multiplexing between channels using 32 internal priority levels, fixed- or round-robin-priority operation, major-minor loop structure, and DONE or DRACK protocol from requesting units. • Two independent TDM modules with independent receive and transmit, programmable sharing of frame sync and clock, programmable word size (8 or 16-bit), hardware-base A-law/ μ-law conversion, up to 50 Mbps data rate per TDM, up to 128 channels, with glueless interface to E1/T1 frames and MVIP, SCAS, and H.110 buses. • Ethernet controller with support for 10/100 Mbps MII/RMII designed to comply with IEEE Std. 802.3™, 802.3u™, 802.3x™, and 802.3ac™; with internal receive and transmit FIFOs and a FIFO controller; direct access to internal memories via its own DMA controller; full and half duplex operation; programmable maximum frame length; virtual local area network (VLAN) tag and priority support; retransmission of transmit FIFO following collision; CRC generation and verification for inbound and outbound packets; and address recognition including promiscuous, broadcast, individual address. hash/exact match, and multicast hash match. • UART with full-duplex operation up to 5.0 Mbps. • Up to 41 general-purpose input/output (GPIO) ports. •I2C interface that allows booting from EEPROM devices up to 1 Mbyte. • Two quad timer modules, each with sixteen configurable 16-bit timers. • fieldBIST™ unit detects and provides visibility into unlikely field failures for systems with high availability to ensure structural integrity, that the device operates at the rated speed, is free from reliability defects, and reports diagnostics for partial or complete device inoperability. • Standard JTAG interface allows easy integration to system firmware and internal on-chip emulation (OCE10) module. • Optional booting external host via 8-bit or 16-bit access through the HDI16, I2C, or SPI using in the boot ROM to access serial SPI Flash/EEPROM devices; different clocking options during boot with the PLL on or off using a variety of input frequency ranges. Low-Cost 16-bit DSP with DDR Controller and 10/100 Mbps Ethernet MAC |
