Freescale Semiconductor Technical Data Freescale reserves the right to change the detail specifications as may be required to permit improvements in the design of its products. This document provides an overview of the MPC8379E PowerQUICC II Pro processor features, including a block diagram showing the major functional components. This chip is a cost-effective, low-power, highly integrated host processor that addresses the requirements of several printing and imaging, consumer, and industrial applications, including main CPUs and I/O processors in printing systems, networking switches and line cards, wireless LANs (WLANs), network access servers (NAS), VPN routers, intelligent NIC, and industrial controllers. This chip extends the PowerQUICC family, adding higher CPU performance, additional functionality, and faster interfaces while addressing the requirements related to time-to-market, price, power consumption, and package size. 1Overview This chip incorporates the e300c4s core, which includes 32 KB of L1 instruction and data caches and on-chip memory management units (MMUs). The device offers two enhanced three-speed 10, 100, 1000 Mbps Ethernet interfaces, a DDR1/DDR2 SDRAM memory controller, a flexible, a 32-bit local bus controller, a 32-bit PCI controller, an optional dedicated security engine, a USB 2.0 dual-role controller, a programmable interrupt Document Number: MPC8379EEC Rev. 8, 05/2012 Contents 1.
