Overview
Preliminary PowerPC 440GX Embedded Processor Data Sheet Features • PowerPC® 440 processor core operating up to 800MHz with 32KB I- and D-caches (with parity checking) • On-chip 256KB SRAM configurable as L2 Code store or Ethernet Packet store memory • Selectable processor:bus clock ratios (Refer to the Clocking chapter in the PPC440GX Embedded Processor User’s Manual for details) • Double Data Rate (DDR) Synchronous DRAM (SDRAM) interface operating up to 166MHz • External Peripheral Bus (32 bits) for up to eight devices with external mastering • DMA support for external peripherals, internal UART and memory • PCI-X V1.
0a interface (32 or 64 bits, up to 133MHz) with support for conventional PCI V2.
3 • Two Ethernet 10/100/1000Mbps half- or fullduplex interfaces.
Operational modes supported are SMII, GMII, RGMII, TBI and RTBI.
• TCP/IP Acceleration Hardware (TAH) provided for 10/100/1000 Mbps ports that performs checksum processing, TCP segmentation, and includes support for jumbo frames • Two Ethernet 10/100Mbps half- or full-duplex interfaces.
Operational modes supported are MII, RMII, and SMII.
• Programmable Interrupt Controller supports interrupts from a variety of sources.
• I2O Messaging unit for message transfer between the CPU and PCI-X • Programmable General Purpose Timers (GPT) • Two serial ports (16750 compatible UART) • Two IIC interfaces • General Purpose I/O (GPIO) interface available • JTAG interface for board level testing • Processor can boot from PCI memory Description Designed specifically to address high-end embedded applications, the PowerPC 440GX (PPC440GX) provides a high-performance, low power solution that interfaces to a wide range of peripherals by incorporating on-chip power management features and lower power dissipation.
This chip contains a high-performance RISC processor core, DDR SDRAM controller, configurable 256KB SRAM to be used as L2 cache or software-controlled on-chip memory, PCI-X bus interface, Gigabit Ethernet interfaces, TC...
