The MPC8315E Communication Processor family supports a broad range of feature-rich applications that make the digital home experience easier, richer and more secure. The cost-effective MPC8315E processor meets the requirements of several small office/home office (SOHO) applications, including customer network attached storage (NAS), digital media servers, residential gateways, WLAN access points, printing, IP business and industrial control. It provides better CPU performance, additional features and faster interface speeds, while meeting important time-to-market, price, power consumption and board space requirements. Its integration of Serial ATA, PCI Express® Gigabit Ethernet, high-speed USB 2.0, TDM and low power management makes it unique in the marketplace. It is particularly suited to applications with extremely precise clock synchronization requirements, such as time-sensitive communication business, industrial network switches, powertrain networks and test/measurement devices.
The MPC8315E series is a communication‑oriented CPU built around Freescale's e300 core, offering up to 400 MHz processing speed, 16 KB L1 cache, and a range of high‑speed interfaces such as PCI Express, SATA, USB 2.0, and Gigabit Ethernet. It targets SOHO and embedded applications that require robust networking, storage, and multimedia capabilities.
Key features include dual‑channel DMA, hardware security accelerators for AES, DES, 3DES, MD5 and SHA‑1, and support for DDR1/DDR2 memory up to 266 MHz. The device is offered in a TEPBGAII package and includes optional security modules and development tools. This manual is written in Chinese.
