Introduction 1
INTRODUCTION
The Flex CPU piggyback board (Part # 300-603605-10x) for the PMAC/PMAC2 and Turbo
PMAC/PMAC2 families of boards provides new high-end capabilities for these controllers and uses
newer components with longer product lifetimes. It can be manufactured in a wide variety of
configurations, and can be used in the following products:
• PMAC(1)-PC
• PMAC(1)-PCI
• PMAC(1)-VME
• PMAC2-PC
• PMAC2-PCI
• PMAC2-VME
• Turbo PMAC(1)-PC
• Turbo PMAC(1)-PCI
• Turbo PMAC(1)-VME
• Turbo PMAC2-PC
• Turbo PMAC2-PCI
• Turbo PMAC2-VME
On the regular (non-Turbo) PMAC(1) and PMAC2 boards, the Flex CPU is provided automatically when
any of the following CPU options are ordered:
• Option 5AF: 40 MHz CPU with 128k x 24 internal SRAM
• Option 5CF: 80 MHz CPU with 128k x 24 internal SRAM
• Option 5EF: 160 MHz CPU with 128k x 24 internal SRAM
The Flex CPU board is not provided if Option 4x or 5x is not ordered, or if Option 4A, 5A, 5B, or 5C is
ordered.
On Turbo PMAC(1) and Turbo PMAC2 boards, the Flex CPU may be provided when any of the
following CPU options is ordered:
• Option 5C0: 80 MHz DSP56303 CPU with 8k x 24 internal SRAM, 256k x 24 external SRAM
• Option 5C3: 80 MHz DSP56303 CPU with 8k x 24 internal SRAM, 1M x 24 external SRAM
• Option 5D0: 100 MHz DSP56309 CPU with 34k x 24 internal SRAM, 256k x 24 external SRAM
• Option 5D3: 100 MHz DSP56309 CPU with 34k x 24 internal SRAM, 1M x 24 external SRAM
In these cases, however, the older Turbo only CPU piggyback board may also be provided.
On Turbo PMAC(1) and Turbo PMAC2 boards, the Flex CPU will be provided automatically when either
of the following CPU options is ordered:
• Option 5E0: 160 MHz DSP56309 CPU with 128k x 24 internal SRAM, 256k x 24 external SRAM
• Option 5E3: 160 MHz DSP56309 CPU with 128k x 24 internal SRAM, 1M x 24 external SRAM
