MSC8252 Reference Manual - Dual Core Digital Signal Processor
Technical reference manual for the NXP MSC8252 Dual Core DSP, detailing the StarCore SC3850 architecture, high-speed interfaces, and integrated QUICC Engine subsystem.
Overview
This reference manual provides a comprehensive technical overview and functional description of the NXP MSC8252 Dual Core Digital Signal Processor. The device is built on the StarCore SC3850 DSP subsystem and includes L1/L2 cache structures, the Chip-Level Arbitration and Switching System (CLASS) for internal fabric management, and M2/M3 memory levels. The manual covers integrated peripherals including dual DDR-SDRAM controllers, DMA controllers, Serial RapidIO, PCI Express, and the QUICC Engine subsystem for Ethernet and SPI. It further details system-level features such as interrupt handling, TDM interfaces, memory mapping, and hardware semaphores for multi-core synchronization.
