• Two SERDES controllers: One Serial Rapid IO (4 lanes) and one PCI Express (4 or 8 lanes)
Memory
AMC131 memory is comprised of the following components:
• SDRAM
• Flash Memory
• Global Storage
• Serial EEPROM
SDRAM
Two 200-pin sockets for DDR2 SDRAM are provided. This memory comprises 64 bits of data
with 8 bits of ECC. Each socket on the module has 238M x 72 bits or 1GB for a total of 2 GB
RAM. The built-in error correction code (ECC) helps ensure data integrity for reliable high-
frequency operations. PT has qualified PC2-3200, 1GB, DDR2 SO-CDIMM for use with the
AMC131. For more information, see
“Memory Configuration,” on page 35 .
For additional SDRAM density options, please contact your PT sales representative.
Memory is not a field serviceable item. Return the module to PT for memory replacement. See
“Return Merchandise Authorization (RMA),” on page 19 for more information about returning
merchandise.
Flash Memory
Onboard, non-volatile, programmable, Flash memory (128 Mb x 8) is provided for startup code
and application storage. This memory is connected to the MPC8641D local bus and is
accessible using the console port (see
Figure 2-1, “AMC131 Front Panel,” on page 23 ).
Global Storage
A mini Secure Digital (miniSD) card is provided for additional non-volatile storage. This card
provides a minimum of 256 MB memory for user code images. For additional miniSD density
options, please contact your PT sales representative. See
“Working with the MiniSD Card,” on
page 35 for information about miniSD card installation and removal.
Serial EEPROM
Serial Electrically Erasable Programmable Read-only Memory (EEPROM, 256K x 1) is
provided for boot initialization values.
