2.3
Address Translation Unit
An Address Translation Unit (ATU) allows PCI transactions direct access to the 80333 local
memory. The ATU supports transactions between PCI address space and 80333 address space.
Address translation for the ATU is controlled through programmable registers accessible from both
the PCI interface and the Intel XScale® core. The PCI interface of the ATU is connected to the
80333 “A” Secondary PCI interface of the bridge. Upstream access to the PCI Express* interface is
controlled by inverse decode with the address windows of the bridge. Dual access to registers
allows flexibility in mapping the two address spaces. The ATU also supports the power
management extended capability configuration header that as defined by the PCI Bus Power
Management Interface Specification, Revision 1.1.
2.4
Memory Controller
The Memory Controller allows direct control of a DDR SDRAM memory subsystem. It features
programmable chip selects and support for error correction codes (ECC). The memory controller
may be configured for DDR SDRAM at 333 MHz (with 500 MHz and 667 MHz processors) or
DDR-II SDRAM at 400 MHz (with 500 MHz and 800 MHz processors). The memory controller is
dual-ported, with a dedicated interface for the Intel XScale® core Bus Interface Unit and a second
interface to the Internal Bus. The memory controller supports pipelined access and arbitration
control to maximize performance. The memory controller interface configuration support includes
Unbuffered DIMMs, Registered DIMMs, and discrete DDR SDRAM devices.
External memory may be configured as host addressable memory or private 80333 memory
utilizing the Address Translation Unit and Bridges.
2.5
2.6
Application Accelerator Unit
The Application Accelerator Unit (AA) provides low-latency, high-throughput data transfer
capability between the AA unit, the 80333 local memory and the PCI bus. It executes data transfers
from and to the 80333 local memory, from the PCI bus to the 80333 local memory, or from the
80333 local memory to the PCI bus. The AA unit performs XOR operations, computes parity,
generates and verifies an eight byte data integrity field, performs memory block fills, and provides
the necessary programming interface. The AA unit in the 80333 has been enhanced to support
RAID 6 functionality.
Peripheral Bus Interface
The Peripheral Bus Interface Unit is a data communication path to the flash memory components
or other peripherals of an 80333 hardware system. The PBI includes support for either 8/16 bit
devices. To perform these tasks at high bandwidth, the bus features a burst transfer capability
which allows successive 8/16-bit data transfers.

DMA Controller
The DMA Controller allows low-latency, high-throughput data transfers between PCI bus agents
and the local memory. Two separate DMA channels accommodate data transfers to the PCI bus.
Both channels include a local memory to local memory transfer mode. The DMA Controller
supports chaining and unaligned data transfers. It is programmable through the Intel XScale® core
only.
I2C Bus Interface Unit
The I2C (Inter-Integrated Circuit) Bus Interface Unit allows the Intel XScale® core to serve as a
master and slave device residing on the I2C bus. The I2C unit uses a serial bus developed by Philips
Semiconductor*, consisting of a two-pin interface. The bus allows the 80333 to interface to other
I2C peripherals and microcontrollers for system management functions. It requires a minimum of
hardware components for an economical system to relay status and reliability information on the
I/O subsystem to an external device. Also refer to I2C Peripherals for Microcontrollers (Philips
Semiconductor).
The 80333 includes two I2C bus interface units.
2.9
Messaging Unit
The Messaging Unit (MU) provides data transfer between the PCI system and the 80333. It uses
interrupts to notify each system when new data arrives. The MU has four messaging mechanisms:
• Message Registers
• Doorbell Registers
• Circular Queues
• Index Registers
Each messaging mechanism allows a host processor or external PCI device and the 80333 to
communicate through message passing and interrupt generation.
2.10
2.11
Internal Bus
The Internal Bus is a high-speed interconnect between internal units and Intel XScale® core
processor. The Internal Bus operates at 333 MHz and is 64 bits wide.
UART Units
The 80333 includes two UART unit. The UART units allow the Intel XScale® core to serve as a
master and slave device residing on the UART bus. The UART units use a serial bus consisting of a
four-pin interface. The bus allows the 80333 to interface to other peripherals and microcontrollers.
Also refer to 16550 Device Specification (National Semiconductor*).

I/O
Serial Output: Composite serial data output to the communications
link-peripheral, modem, or data set. The TXD signal is set to the
MARKING (logic 1) state upon a Reset operation.
General Purpose I/O: These pins may be selected on a per pin
basis as general purpose inputs or outputs. The default mode is a
general purpose input.
Clear To Send: When low, this pin indicates that the receiving UART
is ready to receive data. When the receiving UART deasserts CTS#
high, the transmitting UART should stop transmission to prevent
overflow of the receiving UARTs buffer. The CTS# signal is a modem-
status input whose condition may be tested by the host processor or
by the UART when in Autoflow Mode as described below:
Non-Autoflow Mode:
When not in Autoflow Mode, bit 4 (CTS) of the Modem Status
register (MSR) indicates the state of CTS#. Bit 4 is the complement
of the CTS# signal. Bit 0 (DCTS) of the Modem Status register
indicates whether the CTS# input has changed state since the
previous reading of the Modem Status register. CTS# has no effect
on the transmitter. The user may program the UART to interrupt the
processor when DCTS changes state. The programmer may then
stall the outgoing data stream by starving the transmit FIFO or
disabling the UART with the IER register.
GPIO[2]/
U0_CTS#
1
I/O
Note: When UART transmission is stalled by disabling the UART,
the user may not receive an MSR interrupt when CTS#
reasserts. This occurs because disabling the UART also
disables interrupts. As a workaround, the user may use
Auto CTS in Autoflow Mode, or program the CTS# pin to
interrupt.
Autoflow Mode:
Note: In Autoflow Mode, the UART Transmit circuitry will check
the state of CTS# before transmitting each byte. When
CTS# is high, no data is transmitted.
General Purpose I/O: These pins may be selected on a per pin
basis as general purpose inputs or outputs. The default mode is a
general purpose input.
Request To Send: When low, this informs the remote device that
the UART is ready to receive data. A reset operation sets this signal
to its Inactive (high) state. LOOP mode operation holds this signal in
its Inactive state.
Non-Autoflow Mode:
GPIO[3]/
U0_RTS#
1
I/O
The RTS# output signal may be asserted by setting bit 1 (RTS) of
the Modem Control register to a 1. The RTS bit is the complement
of the RTS# signal.
Autoflow Mode:
RTS# is automatically asserted by the Autoflow circuitry when the
Receive buffer exceeds its programmed threshold. It is deasserted
when enough bytes are removed from the buffer to lower the data
level back to the threshold.

Description
Test Clock provides clock input for IEEE 1149.1 Boundary Scan
Testing (JTAG). State information and data are clocked into the
device on the rising clock edge and data is clocked out on the falling
clock edge.
TCK
1
I
Test Data Input is the JTAG serial input pin. TDI is sampled on the
rising edge of TCK, during the SHIFT-IR and SHIFT-DR states of
Sync(T) the Test Access Port. This signal has a weak internal pull-up to
ensure proper operation when this pin is not being driven.
I
TDI
1
Test Data Output is the serial output pin for the JTAG feature. TDO
is driven on the falling edge of TCK during the SHIFT-IR and SHIFT-
DR states of the Test Access Port. At other times, TDO floats. The
behavior of TDO is independent of RSTIN# or PWRGD.

Test Reset asynchronously resets the Test Access Port controller
function of IEEE 1149 Boundary Scan Testing (JTAG). This pin has
a weak internal pull-up.

No Connect. Do not connect to any signal, power or ground.
Power Fail Delay is used to delay the reset of the memory
controller in a power-fail condition. This allows the self-refresh
command to be sent to the DDR SDRAM array.
I
PWRDELAY
Async
Power Supply Good: Signal that specifies that the motherboard
power supply has stabilized. This signal is used to asynchronously
reset the 80333 when it is low. The low period of this signal must be
long enough for the system power supply to stabilize and for the
base PLLs to lock.
I
PWRGD

Async
Note: This is the same signal as PERST# which is described in
the PCI Express* Card Electromechanical Specification,
Revision 1.0a.
Reset Input brings PCI-specific registers, sequencers, and signals
to a consistent state. When RSTIN# is asserted:
•
•
•
PCI output signals are driven to a known consistent state.
PCI bus interface output signals are three-stated.
Open drain signals such as B_SERR# are floated.
I
RSTIN#
1
Async
RSTIN# may be asynchronous to B_CLKIN when asserted or
deasserted. Although asynchronous, deassertion must be ensured
to be a clean, bounce-free edge.

Notes:
1.
Spread spectrum clocking is allowed with the following three requirements;
a. All device timings must be met including jitter, skew, min./max. clock period. Output rise/fall timing MUST meet
the existing non-spread spectrum specifications.
b. All non-spread Host and PCI functionality must be maintained in the spread-spectrum mode (includes all power
management functions).
c. The minimum clock period cannot be violated. The preferred method is to adjust the spread technique to allow
for modulation above the nominal frequency. This technique is often called “down-spreading”.
Measured at crossing point.

See Figure 16, “PCI/PCI-X TOV(max) Rising Edge AC Test Load” on page 73, Figure 17, “PCI/PCI-X
TOV(max) Falling Edge AC Test Load” on page 74, and Figure 18, “PCI/PCI-X TOV(min) AC Test
Load” on page 74.
3.
4.
Setup time for point-to-point signals applies to REQ# and GNT# only. All other signals are bused.
See the timing measurement conditions in Figure 8, “Input Timing Measurement Waveforms” on
page 70.
5.
6.
7.
RST# is asserted and deasserted asynchronously with respect to CLK.
All output drivers must be floated when RST# is active.
For purposes of Active/Float timing measurements, the HI-Z or ‘off’ state is defined to be when the
total current delivered through the component pin is less than or equal to the leakage current
specification.
8.
Setup time applies only when the device is not driving the pin. Devices cannot drive and receive
signals at the same time.
