Sam440ep

Sam440, also known by Sam or its codename Samantha, is a line of modular motherboards produced by the Italian company ACube Systems Srl. The Sam440ep version is a Power Architecture motherboard based on the PowerPC 440EP system-on-a-chip processor which includes a double-precision FPU. It is made by AMCC. Their primary targets are the industrial and embedded markets, running operating systems such as Linux and AmigaOS 4.

At the time of release in 2008, it was the only AmigaOS 4 compatible hardware since the AmigaOne machines ceased in 2006; as of April 2009 Sam440 was the only Amiga-compatible board in production and now is succedeed with Sam460ex and forthcoming AmigaOne X1000.

• 4× Serial ATA ports
• Cirrus Logic CS4281 and Realtek ALC655 audio
• ATI Radeon Mobility M9 graphics with 64 MB VRAM, s-video and DVI out.
• GPIO expansion connector
• Lattice XP expansion FPGA

Revision C

The specifications are the same as for the revisions before, except for:

• 1× DDR RAM slot supporting up to 512 MB RAM (in place of soldered RAM moduls)

Sam440ep-flex

Sam440ep-flex motherboard.

There is no graphics chip on the Sam440ep-flex, so you have to use a PCI-graphics board.

Prototype

• 400/533/667 MHz AMCC PowerPC 440EP SoC processor
• Cache L1/L2: 32KB/-
• 512 MB DDR SDRAM soldered to the motherboard
• 1× 32-bit, 66 MHz PCI slot
• 2× 32-bit, 33 MHz PCI slot
• USB 2.0 OHCI/EHCI NXP PCI controller
• 2× Ethernet 10/100 ports
• 4× Serial ATA ports

• GPIO expansion connector
• FPGA Lattice XP with 80 pin I/O expansion connector
• ZigBee module (optional)

Revision 1

Sam440ep-flex Revision 1.

The specifications are the same as for the flex prototype, except for:

• 2× DDR SDRAM, max 1 GB RAM

Revision 2

In 2 April 2009, ACube announced the availability of SAM440ep-flex revision 2, it has the same specifications as the flex prototype except for:

• 667/733/800 MHz AMCC PowerPC 440EP SoC processor (passive cooling, 733 and 800 MHz are achieved by overclocking)
• Cache L1/L2: 32KB/-
• 2× DDR SDRAM, max 1 GB RAM
