Turbo PMAC2 PCI Hardware Reference Manual

2 Introduction

Option 5: CPU and Memory Configurations

The various versions of Option 5 provide different CPU speeds and main memory sizes on the piggyback

CPU board. Only one Option 5xx may be selected for the board.

The CPU is a DSP5630x IC as component U1. It is currently available only as an 80 MHz device (with

computational power equivalent to a 120 MHz non-Turbo PMAC), but higher speed versions will be

available shortly.

The compiled/assembled-program memory SRAM ICs are located in U14, U15, and U16. These ICs

form the active memory for the firmware, compiled PLCs, and user-written phase/servo algorithms.

These can be 128k x 8 ICs (for a 128k x 24 bank), fitting in the smaller footprint, or they can be the larger

512k x 8 ICs (for a 512k x 24 bank), fitting in the full footprint.

The user-data memory SRAM ICs are located in U11, U12, and U13. These ICs form the active memory

for user motion programs, uncompiled PLC programs, and user tables and buffers. These can be 128k x 8

ICs (for a 128k x 24 bank), fitting in the smaller footprint, or they can be the larger 512k x 8 ICs (for a

512k x 24 bank), fitting in the full footprint.

The flash memory IC is located in U10. This IC forms the non-volatile memory for the board’s firmware,

the user setup variables, and for user programs, tables, and buffers. It can be 1M x 8, 2M x 8, or 4M x 8

in capacity.

Option 4C provides an 80 MHz DSP56309 CPU with expanded internal memory to improve

performance for large number of commutated axes.

• Option 5C0 is the standard CPU and memory configuration. It is provided automatically if no Option

5xx is specified. It provides an 80 MHz CPU (120 MHz PMAC equivalent), 128k x24 of

compiled/assembled program memory, 128k x 24 of user data memory; and a 1M x 8 flash memory.

• Option 5C1 provides an 80 MHz CPU (120 MHz PMAC equivalent), 128k x 24 of

compiled/assembled program memory, an expanded 512k x 24 of user data memory, and a 2M x 8

flash memory.

• Option 5C2 provides an 80 MHz CPU (120 MHz PMAC equivalent), an expanded 512k x 24 of

compiled/assembled program memory, 128k x 24 of user data memory, and a 2M x 8 flash memory.

• Option 5C3 provides an 80 MHz CPU (120 MHz PMAC equivalent), an expanded 512k x 24 of

compiled/assembled program memory, an expanded 512k x 24 of user data memory, and a 4M x 8

flash memory.

• Option 5D0 provides a 100 MHz CPU (120 MHz PMAC equivalent), 128k x24 of

compiled/assembled program memory, 128k x 24 of user data memory; and a 1M x 8 flash memory.

It is not compatible with Option-4C.

• Option 5D1 provides a 100 MHz CPU (120 MHz PMAC equivalent), 128k x 24 of

compiled/assembled program memory, an expanded 512k x 24 of user data memory, and a 2M x 8

flash memory. Check with the factory for availability.

• Option 5D2 provides a 100 MHz CPU (120 MHz PMAC equivalent), an expanded 512k x 24 of

compiled/assembled program memory, 128k x 24 of user data memory, and a 2M x 8 flash memory.

Check with the factory for availability.

• Option 5D3 provides a 100 MHz CPU (120 MHz PMAC equivalent), an expanded 512k x 24 of

compiled/assembled program memory, an expanded 512k x 24 of user data memory, and a 4M x 8

flash memory. Check with the factory for availability.

Option 7: Plate Mounting

Option 7 provides a mounting plate connected to the Turbo PMAC2 PCI with standoffs. It is used to

install the Turbo PMAC2 PCI in standalone applications.
