12.1 Introduction
The Static Memory Controller (SMC) operates in little endian mode, and it supports up to six
independently configurable memory spaces or banks. Supported memory types are:
Each memory bank can be configured to support:
Note: In the EP9301 and 9302 processors, the common address/data bus is 16-bits wide
Note: In the EP9307, EP9312, and EP9315 processors, the common address/data bus is
Note: PCMCIA (PC Card) is supported in the EP9315 processor only.
Note: There are only two external DMA interfaces total on the EP93xx device to control data flow
• SRAM
• ROM
• NOR FLASH
• External Peripheral that has an SRAM-type interface
• Memory devices that have either 8-, 16-, or 32-bit data paths. For example:
• One external peripheral that uses the external DMA handshake signals, DREQ0/1,
• Non-burst read and write accesses
• Page Mode (burst-of-four) read and write accesses
• PCMCIA interfacing (EP9315 processor only)
DACK0/1, and optionally DEOT0/1. These signals are multiplexed with EPGIO[12:7]
pins.
• Two 16-bit devices can be used in parallel to make a 32-bit data path
• Two 8-bit devices can be used in parallel to make a 16-bit data path
• One 16-bit device can be used standalone to make an 16-bit data path
• One 8-bit device can be used standalone to make an 8-bit data path
and the Static Memory Controller (SMC) supports 8-bit and 16-bit devices.
programmable to either 16-bits or 32-bits wide, and the SMC supports 8-bit, 16-bit,
and 32-bit devices.
