The flash memory IC is located in U26. 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 5C0: Default CPU speed and memory configuration: 80MHz DSP56303 CPU
(8Kx24 internal memory), 128Kx24 SRAM compiled/assembled program memory,
128Kx24 SRAM user data memory, 1Mx8 flash memory.
• Option 5C3: Default CPU speed and memory configuration: 80MHz DSP56303 CPU
(8Kx24 internal memory), expanded 512Kx24 SRAM compiled/assembled program
memory, expanded 512Kx24 SRAM user data memory, 4Mx8 flash memory.
• Option 5F3: 240MHz DSP56321 CPU (192Kx24 internal memory), expanded 512Kx24
SRAM compiled/assembled program memory, expanded 512Kx24 SRAM user data
memory, 4Mx8 flash memory.
Option 10: Firmware Version Specification
Normally the Turbo PMAC2 Eth Ultralite is provided with the newest released firmware version.
The response to the VERSION query command shows which firmware revision is presently
installed. Option 10 provides for a user-specified firmware version.
Option 12: Analog-to-Digital and Digital-to-Analog Converters
Option 12 permits the installation of 2 channels of on-board analog-to-digital converters and one
channel of on-board digital-to-analog converter.
The analog inputs are not optically isolated, and each can have a +/- 10V input range, or a +/-5V
input range if differential signal is used, individually selectable with a 12-bit resolution.
The analog output is a 12-bit DAC have +/-10V output range.
