Integrated Drive Electronics (IDE)
Interface Reduces BOM Costs
With the EP9312’s built-in IDE interface,
the processor can connect directly with
multiple hardware devices such as hard
drives, CD drives and DVD drives. This
saves designers money by minimizing
their BOM costs, reduces their product
size by shrinking board space and gets
their products to market faster by saving
design time. The IDE interface provides
an industry standard connection to two
AT Advanced Packet Interface (ATAPI)
compliant devices. A single IDE port
attaches to both master and slave
devices. The interface supports three
transfer modes corresponding to a range
of transfer rates. These modes are Polled
I/O, Multiword DMA and Ultra DMA.
High Quality Sound Delivered in
Multiple Audio Configurations
The EP9312 delivers SPI, I2S and
AC ’97 serial interface support. The
processor can be configured to provide
up to six-channel I2S 24-bit audio. The
AC ’97 port supports multiple CODECs
for cost-effective stereo audio output.
Cirrus Logic provides high-performance
audio decode and encode algorithms
for a number of popular formats
including MP3, WMA and AAC.
General-Purpose Memory Interface
(SDRAM, SRAM, ROM, & FLASH)
The EP9312 features a unified memory
address model in which all memory
devices are accessed over a common
address/data bus. A separate internal
port is dedicated to the read-only Raster/
Display refresh engine, while the rest
of the memory accesses are performed
via the high-speed processor bus. The
SRAM memory controller supports 8, 16
and 32-bit devices and accommodates
an internal boot ROM concurrently
with a 32-bit SDRAM memory.
16-Bit Analog-to-Digital Converter (ADC)
Provides an Integrated Touch-Screen Interface
or General ADC Functionality
The EP9312 includes a 16-bit ADC,
which can be utilized either as a 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 processor
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.
8x8 Keypad Interface Reduces BOM Costs
The keypad circuitry scans an 8x8 array
of 64 normally open, single pole switches.
Any one or two keys depressed will be
de-bounced and decoded. An interrupt
is generated whenever a stable set of
depressed keys is detected. If the keypad
is not utilized, the 16 column/row pins
may be used as general-purpose I/Os.
Multiple Booting Mechanisms
Increase Flexibility
The processor includes a 16 KB boot
ROM to set up standard configurations.
Optionally, the processor may be booted
from FLASH memory, over the SPI serial
interface or through the UART. This boot
flexibility makes it easy to design user-
controlled, field-upgradable systems.
Abundant General Purpose I/Os
Build Flexible Systems
The EP9312 includes both enhanced
and standard general- purpose I/O pins
(GPIOs). The 16 different enhanced
GPIOs may individually be configured as
inputs, outputs or interrupt-enabled inputs.
There are an additional 49 standard
GPIOs that may individually be used as
inputs, outputs or open-drain pins. The
standard GPIOs are multiplexed with
peripheral function pins, so the number
available depends on the utilization of
peripherals. Together, the enhanced
and standard GPIOs facilitate easy
system design with external peripherals
not integrated on the EP9312.
