• Memory Integrated controllers for DDR and DDR2 SDRAM to support system memory requirements.
• High-speed Ethernet One three-speed UCC Ethernet controller supporting 10/100/1000 Mbps operation and MII management as described in the family documentation.
• USB Integrated USB 1.x interface (1) for peripheral connectivity.
• Security On-chip cryptography support and a hardware random number generator to assist secure communications and key generation.
• Peripheral and I/O Subsystem Comprehensive embedded peripheral set shown in the family datasheet including PCI, I2C, SPI, JTAG, DUART, timers, GPIO, HDLC and TDM/SI interfaces.
• Package and Mounting 668-PBGA-PGE (29×29) supplier package in tray format, surface-mount mounting for compact board integration.
• Operating Range Specified operating temperature range from 0 °C to 105 °C for consumer-class applications.

Typical Applications

• DSLAMs and Access Equipment Use the MPC8358E family’s integrated communications peripherals and DDR/DDR2 support for aggregation and line-card control functions.
• 3G Base Station Network Interface Cards (Node B) Single-core processing and high-speed Ethernet enable control-plane tasks and packet interfacing in wireless infrastructure cards.
• Routers and Media Gateways On-chip Ethernet, PCI, and protocol-oriented peripherals support data-plane and control-plane roles in routing and media gateway designs.
• High-end IADs Integrated interfaces and security features help implement voice/data aggregation and secure communications in integrated access devices.

Unique Advantages

• Highly integrated communications processor: PowerQUICC II Pro architecture combines core logic with an extensive set of networking and peripheral blocks to reduce external component count.
• Balanced performance and efficiency: A 266 MHz PowerPC e300 core provides deterministic 32-bit processing for control and data tasks without excessive power or complexity.
• Flexible memory support: DDR and DDR2 SDRAM controllers allow designers to select memory technology appropriate to system bandwidth and cost targets.
• Embedded security primitives: Hardware cryptography and an RNG provide building blocks for secure communication features required in telecom and networking equipment.
• Broad peripheral set for protocol handling: On-chip controllers listed in the family documentation (Ethernet, PCI, I2C, SPI, HDLC, TDM/SI and more) simplify protocol interfacing and accelerate system integration.
• Compact PBGA packaging: 668-PBGA-PGE (29×29) surface-mount format supports dense board layouts for space-constrained designs.
