Introduction
EP93xx User’s Guide

bits wide, the SMC supports 8-bit, 16-bit, and 32-bit devices, and the SDRAM, SyncROM,
and SyncFLASH synchronous memory controller supports 16-bit and 32-bit devices. In the
EP9307, EP9312, and EP9315 processors, a separate internal bus to the dynamic memory
controller is dedicated to the read-only Raster/Display refresh engine.
1.4.10 12-Bit Analog-to-Digital Converter (ADC) Provides an Integrated
Touch-Screen Interface or General ADC Functionality
The EP9301 and EP9302 processors include a 5-channel ADC. The EP9307, EP9212, and
EP9315 processors include a 12-bit ADC, which can be utilized either as an 8-wire touch-
screen interface or for general ADC functionality. The touch-screen interface performs all
sampling, averaging, ADC range checking, and control for a wide variety of analog-resistive
touch screens. To improve system performance, the controller only interrupts the ARM Core
when a meaningful change occurs. The touch screen hardware may be disabled, and the
switch matrix and ADC controlled directly for general ADC usage if desired.
1.4.11 Raster Analog / LCD Controller
The EP9307, EP9312, and EP9315 processors include a raster/LCD controller that features
fully programmable video interface timing for either non-interlaced or dual scan color and
grayscale flat panel displays. Resolutions up to 1024x768 pixels are supported from a unified
SDRAM-based frame buffer with pixel depths of 4, 8, 16, or 18 bits. A 256x18 color lookup
table, a hardware blinking cursor with up to 64x64 pixels, and an interface to smart panel
displays is also included.
1.4.12 Graphics Accelerator
The EP9307 and EP9315 processors include a hardware graphics acceleration engine that
improves graphic performance by handling block copy, block fill and hardware line draw
operations. The graphics accelerator is used to off load graphics operations from the ARM
Core.
1.4.13 PCMCIA Interface
The EP9315 processor (only) provides a PCMCIA interface that supports 8-bit or 16-bit
PCMCIA PC Cards. These PCMCIA cards are credit card sized peripherals that add memory,
mass storage and I/O capabilities to computer systems, and can be used to further broaden
the options of a designer’s platform.
