GENERAL INTRODUCTION
1.2FEATURES
• | PowerPC™ Processor | An AMCC 440GX embedded processor based on the AMCC |
|
| PowerPC superscalar core. It operates at a maximum frequency of |
|
| 667 MHz internally. |
• | SDRAM | Up to 512 MByte of 333 MHz DDR SDRAM is supported via a 200 |
|
| pin SoDIMM module. |
• | Flash ROM | 8 Mbytes of |
|
| |
|
| Flash ROM is reserved for the storage of |
|
| system parameters. System calls for storing parameters in this |
|
| memory are included in the Breeze Development Environmentª |
• | Console Serial Port | An asynchronous serial port based on a 16C750 UART with an RS- |
|
| 232 interface is provided for a console terminal or workstation |
|
| connection. |
• | Ethernet Ports | Two 10/100/1Gb |
|
| supports up to 1Gbps and uses a RJ45 style modular phone jack. The |
|
| MAC contained within the 440GX interfaces with 2 Broadcom |
|
| BMC5461S PHY transceivers. |
|
| Two 10/100 |
|
| and also uses a RJ45 style modular phone jack. In this case the MAC |
|
| contained within the 440GX interfaces with a Broadcom BCM5248. |
|
| The BCM5248 is an eight port PHY, but we are only using the first 2 |
|
| ports. |
• | Temperature Sensors | Two LM75 type programmable temperature sensors with interrupt |
|
| signaling capability are provided for system monitoring purposes. |
• | I2O Messaging | The |
|
| communication. |
• | DMA Controller | The 440GX supports 4 separate DMA channels for high throughput |
|
| data transfers between PCI bus agents and the local SDRAM |
|
| memory. |
• | Breeze Development | |
| Environment™ | |
|
| More information on the Breeze Development Environment™ can |
|
| be found in Breeze Developer’s Manual. |
• | Blade Style Interface | The |
|
| geographic addressing from J1 and J2. Note that the fan detect and |
|
| power supply status signals are only available when a |
|
| installed in the system slot. |
• | Hot Swap | The |
|
| 2.1. |
