OVERVIEW (cont.)
The EP7309 is designed for ultra-low-power operation. Its core
operates at only 2.5 V, while its I/O has an operation range of
2.5 V–3.3 V. The device has three basic power states:
operating, idle and standby.
The EP7309 integrates an interface to enable a direct
connection to many low cost, low power, high quality audio
converters. In particular, the DAI can directly interface with
the Crystal‚ CS43L41/42/43 low-power audio DACs and the
Crystal‚ CS53L32 low-power ADC. Some of these devices
feature digital bass and treble boost, digital volume control and
compressor-limiter functions.
MaverickKey unique hardware programmed IDs are a solution
to the growing concern over secure web content and
commerce. With Internet security playing an important role in
the delivery of digital media such as books or music,
traditional software methods are quickly becoming unreliable.
The MaverickKey unique IDs provide OEMs with a method of
utilizing specific hardware IDs such as those assigned for
SDMI (Secure Digital Music Initiative) or any other
authentication mechanism.
Simply by adding desired memory and peripherals to the
highly integrated EP7309 completes a low-power system
solution. All necessary interface logic is integrated on-chip.

EP7309
High-Performance, Low-Power System on Chip
Both a specific 32-bit ID as well as a 128-bit random ID is
programmed into the EP7309 through the use of laser probing
technology. These IDs can then be used to match secure
copyrighted content with the ID of the target device the
EP7309 is powering, and then deliver the copyrighted
information over a secure connection. In addition, secure
transactions can benefit by also matching device IDs to server
IDs. MaverickKey IDs provide a level of hardware security
required for today’s Internet appliances.
Processor Core - ARM720T
The EP7309 incorporates an ARM 32-bit RISC
microcontroller that controls a wide range of on-chip
peripherals. The processor utilizes a three-stage pipeline
consisting of fetch, decode and execute stages. Key features
include:
•
•
ARM (32-bit) and Thumb (16-bit compressed) instruction
sets
Memory Interfaces
Enhanced MMU for Microsoft Windows CE and other
operating systems
The EP7309 is equiped with a ROM/SRAM/FLASH-style
interface that has programmable wait-state timings and
includes burst-mode capability, with six chip selects decoding
six 256 MB sections of addressable space. For maximum
flexibility, each bank can be specified to be 8-, 16-, or 32-bits
wide. This allows the use of 8-bit-wide boot ROM options to
minimize overall system cost. The on-chip boot ROM can be
used in product manufacturing to serially download system
code into system FLASH memory. To further minimize system
memory requirements and cost, the ARM Thumb instruction
set is supported, providing for the use of high-speed 32-bit
operations in 16-bit op-codes and yielding industry-leading
code density.

Power Management
The EP7309 is designed for ultra-low-power operation. Its core
operates at only 2.5 V, while its I/O has an operation range of
2.5 V–3.3 V allowing the device to achieve a performance
level equivalent to 60 MIPS. The device has three basic power
states:
• Operating — This state is the full performance state.
All the clocks and peripheral logic are enabled.
• Idle — This state is the same as the Operating State,
except the CPU clock is halted while waiting for an
event such as a key press.

The EP7309 uses its powerful 32-bit RISC processing engine
to implement audio decompression algorithms in software. The
nature of the on-board RISC processor, and the availability of
efficient C-compilers and other software development tools,
ensures that a wide range of audio decompression algorithms
can easily be ported to and run on the EP7309

Interrupt Controller
LCD Controller
When unexpected events arise during the execution of a
program (i.e., interrupt or memory fault) an exception is
usually generated. When these exceptions occur at the same
time, a fixed priority system determines the order in which
they are handled. The EP7309 interrupt controller has two
interrupt types: interrupt request (IRQ) and fast interrupt
request (FIQ). The interrupt controller has the ability to control
interrupts from 22 different FIQ and IRQ sources.
A DMA address generator is provided that fetches video
display data for the LCD controller from memory. The display
frame buffer start address is programmable, allowing the LCD
frame buffer to be in SDRAM, internal SRAM or external
SRAM.

Real-Time Clock
Matrix keyboards and keypads can be easily read by the
EP7309. A dedicated 8-bit column driver output generates
strobes for each keyboard column signal. The pins of Port A,
when configured as inputs, can be selectively OR'ed together
to provide a keyboard interrupt that is capable of waking the
system from a STANDBY or IDLE state.
The EP7309 contains a 32-bit Real Time Clock (RTC) that can
be written to and read from in the same manner as the timer
counters. It also contains a 32-bit output match register which
can be programmed to generate an interrupt.

SYSCON2. The choice between the SSI2, CODEC, and the
DAI is controlled by the DAISEL bit in SYSCON3 (see the
EP7309 User’s Manual for more information).

Refer to the strength column in the pin assignment tables for all package types.
Assumes buffer has no pull-up or pull-down resistors.
The leakage value given assumes that the pin is configured as an input pin but is not currently being driven.
Note: 1) Total power consumption = IDDCORE x 2.5 V + IDDIO x 3.3 V
2) A typical design will provide 3.3 V to the I/O supply (i.e., VDDIO), and 2.5 V to the remaining logic. This is to allow the I/O to be
compatible with 3.3 V powered external logic (i.e., 3.3 V SDRAMs).
2) Pull-up current = 50 µA typical at VDD = 3.3 V.

18.432 MHz, and 77 ns at 13 MHz), by either driving EXPRDY low and/or by programming a number of wait states. EXPRDY is
sampled on the falling edge of EXPCLK before the data transfer. If low at this point, the transfer is delayed by one clock period
where EXPRDY is sampled again. EXPCLK need not be referenced when driving EXPRDY, but is shown for clarity.

Figure 5. Static Memory Burst Read Cycle Timing Measurement
Note: 1. Four cycles are shown in the above diagram (minimum wait states, 1-0-0-0). This is the maximum number of consecutive
cycles that can be driven. The number of consecutive cycles can be programmed from 2 to 4, inclusively.
2. The cycle time can be extended by integer multiples of the clock period (22 ns at 45 MHz, 27 ns at 36 MHz, 54 ns at
18.432 MHz, and 77 ns at 13 MHz), by either driving EXPRDY low and/or by programming a number of wait states. EXPRDY is
sampled on the falling edge of EXPCLK before the data transfer. If low at this point, the transfer is delayed by one clock period
where EXPRDY is sampled again. EXPCLK need not be referenced when driving EXPRDY, but is shown for clarity.
3. Consecutive reads with sequential access enabled are identical except that the sequential access wait state field is used to
determine the number of wait states, and no idle cycles are inserted between successive non-sequential ROM/expansion
cycles. This improves performance so the SQAEN bit should always be set where possible.
4. Address, Halfword, Word, and Write hold state until next cycle.

General Conventions
Pin Description Conventions
Hexadecimal numbers are presented with all letters in
uppercase and a lowercase “h” appended or with a 0x at the
beginning. For example, 0x14 and 03CAh are hexadecimal
numbers. Binary numbers are enclosed in single quotation
marks when in text (for example, ‘11’ designates a binary
number). Numbers not indicated by an “h”, 0x or quotation
marks are decimal.
Abbreviations used for signal directions are listed in Table 25.

Registers are referred to by acronym, with bits listed in
brackets separated by a colon (:) (for example, CODR[7:0]),
and are described in the EP7309 User’s Manual. The use of
“TBD” indicates values that are “to be determined,” “n/a”
designates “not available,” and “n/c” indicates a pin that is a
“no connect.”
