Introduction

1.1 About the AHB MC

The AHB MC is an Advanced Microcontroller Bus Architecture (AMBA) compliant

System-on-Chip (SoC) peripheral. It is developed, tested, and licensed by ARM

Limited.

The AHB MC takes advantage of the newly developed Static Memory Controller

(SMC). The AHB MC has an AHB port with access to the external memory. The AHB

port has a bridge interface to the memory controller. There is a separate AHB port to

configure the memory controller. Specific configurations of the SMC are instantiated to

target specific memory devices. Figure 1-1 shows the AHB MC (PL241) configuration.

This section describes:

• AHB interface on page 1-3

• AHB to APB bridge on page 1-3

• SMC on page 1-4

• Clock domains on page 1-4

• Low-power interfaces on page 1-4.
