Sam440, also known by Sam or its codename Samantha,[1][2] is a line of modular motherboards produced by the Italian company ACube Systems Srl.[3] 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.[4][5] 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 succeeded by the Sam460ex (AmigaOne 500) and AmigaOne X1000.

Sam440ep was the first modular motherboard produced by ACube Systems Srl.[4]

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 modules)

Sam440ep-flex

There is no graphics chip on the Sam440ep-flex, so you have to use a PCI-graphics board.[7]

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
  • Ethernet 10/100 ports
  • Serial ATA ports
  • Cirrus Logic CS4281 and Realtek ALC655 audio
  • GPIO expansion connector
  • FPGA Lattice XP with 80 pin I/O expansion connector
  • ZigBee module (optional)

Revision 1

The specifications[8] are the same as for the flex prototype, except for:

  • 2× DDR SDRAM, max 1 GB RAM

Revision 2

On 2 April 2009, ACube announced the availability of SAM440ep-flex revision 2, it has the same specifications as the flex prototype except for:[9]

  • 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
  • RAM clock running at 133 MHz (667 and 800 MHz models) or at 147 MHz (733 MHz models)[10]
