AMC Overview and Features

The following sections describe the features of the AMC.

Features

The EBIU AMC features include:
• I/O width 16-bit, I/O supply 2.5 or 3.3 V
• Maximum throughput of 133 M bytes/second
• Supports up to 4M byte of SRAM in four external banks
• AMC supports 8-bit data masking writes
• AMC has control of the EBIU while auto-refresh is performed to
SDRAM
• AMC supports asynchronous access extension (
• Supports instruction fetch
• Allows booting from bank 0 (

Asynchronous Memory Interface

The asynchronous memory interface allows a glueless interface to a variety
of memory and peripheral types. These include SRAM, ROM, EPROM,
flash memory, and FPGA/ASIC designs. Four asynchronous memory
regions are supported. Each has a unique memory select associated with it,
