Turbo PMAC2 VME Ultralite

Introduction 3

• Option 5D3: 100MHz DSP56309 CPU (34Kx24 internal memory), expanded 512Kx24 SRAM

compiled/assembled program memory, expanded 512Kx24 SRAM user data memory, 4Mx8 flash

memory.

• Option 5E0 160MHz DSP56311 CPU (128Kx24 internal memory), 128Kx24 SRAM

compiled/assembled program memory, 128Kx24 SRAM user data memory, 1Mx8 flash memory.

• Option 5E3: 160MHz DSP56311 CPU (128Kx24 internal memory), expanded 512Kx24 SRAM

compiled/assembled program memory, expanded 512Kx24 SRAM user data memory, 4Mx8 flash

memory.

Option 7: Plate Mounting

Option 7 provides a mounting plate connected to the PMAC with standoffs. It is used to install the

PMAC in standalone applications.

Option 8: High-Accuracy Clock Crystal

The Turbo PMAC2 VME Ultralite has a clock crystal (component Y5 of nominal frequency 19.6608

MHz (~20 MHz). The standard crystal’s accuracy specification is +/-100 ppm. Option 8A provides a

nominal 19.6608 MHz crystal with a +/-15 ppm accuracy specification.

Option 9: Auxiliary Serial Port

The Turbo PMAC2 VME Ultralite comes standard with a single serial port, configurable as RS-232 or

RS-422. Optionally a second serial port can be added. Option 9T adds an auxiliary RS-232 port in the

CPU section.

Option 10: Firmware Version Specification

Normally the Turbo PMAC2 VME Ultralite is provided with the newest released firmware version. A

label on the U45 flash memory IC shows the firmware version loaded at the factory. Option 10 provides

for a user-specified firmware version.

Option 16A: Battery-Backed Parameter Memory

The contents of the standard memory are not retained through a power-down or reset unless they have

been saved to flash memory first. Option 16A provides a 32k x 24 bank of battery-backed parameter

RAM in components U41, U44, and U48 for real-time parameter storage. This is ideal for holding

machine state parameters in case of an unexpected power-down. The battery is located at component

BT1.

Option 18A: Electronic Identification

Option 18A provides a module at location U67 that contains an electronic identification feature.
