Chapter 18
Synchronous DRAM Controller Module
18.1
This chapter describes configuration and operation of the synchronous DRAM (SDRAM)
controller. It begins with a general description and brief glossary, and includes a description of
signals involved in DRAM operations. The remainder of the chapter describes the programming
model and signal timing, as well as the command set required for synchronous operations. It also
includes extensive examples that the designer can follow to better understand how to configure the
DRAM controller for synchronous operations.

Introduction
The timing diagrams within this chapter show 32 address lines,
A[31:0]. However, only the lowest 24 address signals are available
externally on the MCF5235 device, A[23:0].
