Note:

The subsections that follow give a brief overview of each feature. Refer to the

appropriate chapter in the

Intel

81341 and 81342 I/O Processors Developer’s Man ual

for full technical descriptions.

2.1.1 Host Interface

81341 and 81342 I/O Processors can be se t up as either a sing le or dual-function P CI

device, providing PCI-X or PCI Express* interface or both P C I-X and PCI E xpress *

interfaces. The PCI interface is selected as a reset option. Each function is

independently controlled and provides the TPMI interface.

Intel

81341 and 81342 I/O Processors are a single-fun ction PCI device tha t provides

either a PCI-X or PCI Express* host interface. The Address Translation Unit (ATU) and

the Messaging Unit (MU) provide the programming interface between the host

processor and the Intel

81341 and 81342 I/O Processors. When PCI-X 1.0b is

selected as the upstream (host) I/O in terface, PCI Ex press* is available as a private

(not visible to the host), downstream I/O interface. Likewise, w hen PCI Express* is

selected as the upstream I/O in terface, PCI-X 1.0b is available as a private,

downstream I/O interface. The sele ction of the upstream I/O in terface is a reset strap

option.

2.1.2 Internal Busse s

The 81341 and 81342 I/O Processors are built around two internal busses: north

internal bus and south internal bus. The two busses use the same bus protocol. The

north internal bus is 128 bits wide and operates at 400 MHz. The north bus connects

the two Int el XScale

processors, which have direct access to the DDR2 SDRAM and

SRAM. The north XSI bus is des igned to provide the two Inte l XSca le

processors with

low-latency access.

The south internal bus is 128 bits wide and operates at 400 MHz. The south XSI bus

provides the data paths for burst transac tions gene rate d by the DMAs. The south XSI

bus internal address and data busses are parity -protect ed on a byte-wise basis. Agents

on the south XSI bus can gen erate an d check address and data parity. The point-to-

point interfaces between the agents and the DDR2 and SRAM Memory Controllers are

also parity-protected on a byte-wise basis.

2.1.3 Application DMA Controllers

There are three Application DMA Con trollers. The Application DMA Controller is dual-

ported—with one of its ports connected to the south XSI bus and the other port to the

DDR2 SDRAM Memory Controller. This Application DMA Controller allows low-latency,

high-throughput data transfers between PCI bus agents and the DDR2 memory. The

DM A controller also allows data transfer between DDR2 Memory. The DMA Controller

supports chaining and unaligned data transfers. It is programmable throug h th e Intel

XScale

processor and the host processor.

In addition to simple data transfers, the ADMA performs XO R operatio ns w ith up to 16

sources.

2.1.4 Address Translation Unit

The Address Translation Unit (ATU) allows PCI transactions direct access to the 81341

and 81342 I/O Processors local memory. The ATU provides interface for the RAID

Controller PCI function. The ATU supports transactions between PCI address space and

the 81341 and 81342 I/O Processors addres s spa ce. Addres s translation i s co ntrolle d

through programmable registers accessible from both the PCI interface and the Intel

XScale

processor. Dual access to registers allows flexibility in mapping the two

address spaces. The ATU also supports the f ollow ing extende d capa bility config uration

headers:

1. Power Management header, as defined by

PCI Bus Power Management Interface

Specification

, Revision 1.1.

2. Message Signaled Interrupt capability structure, as specified in

PCI Local Bus

Specification

, Revision 2.3.

3. PCI-X Ca pabilities List Item, as specif ied in the

PCI-X Adde nd um to the Local Bu s

Specification,

Revision 1.0b.

2.1.5 Messaging Unit

The Messaging Unit (MU) prov ides da ta transfe r betwee n the P CI system and the

81341 and 81342 I/O Processors. It uses interrupts to notify e a ch system when new

data arrives. The MU has four messaging mechanisms: Message Registers, Doorbell

Registers, Circular Queues, and Inde x Re gisters. Each allows a host processor or

external PCI device and the 81341 and 81342 I/O Proce sso rs to co mmunicate th roug h

me ss ag e p as sing and in t e r rupt ge ne rati on . T he MU , in conj u nc tion wit h t h e ATU , ex i sts

2.1.6 DDR2 Memory Controller

The DDR2 Memory Controller allows direct control of the 400/533 MHz DDR2 SDRAM

memory subsystem. It features programmable chip selects and support for error-

correction codes (ECC). The DDR2 Memory Controller is multi-port ed with the following

interfaces: south internal bus, ADMA controllers, north internal bus. The memory

controller interface configuration support includes unbuffered DIMM s, registered

DIMMs, and discrete DDR2 SDRAM devices.

2.1 . 7 SRA M Me mor y Con tr ol le r

The SRAM Mem o ry Con trolle r allow s dire ct con trol o f a 1.0 M Byte S RAM memory

subsystem. It supports error correction codes (E CC). The SRAM is used to store

firmware code, I/O exchange c ontexts and for general-purpose data storage.

2.1.8 Peripheral Bus Interface

The Peripheral Bus Interface Un it is a d ata co mmunication path to the flash memory

components or other peripherals of a 81341 and 81342 I/O Processors hardware

system. The PBI includes support for either 8- or 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.

2.1.9 I

C Bus Interface Units

There are three I

C (Inter-Integrated Circuit) Bus Interface Units that allow the Intel

XScale

processor to serve as a mas ter and slave device residing on the I

C bus. The

C0 allows the I/O processor to interface to a Storage Enclo sure Proce ssor (SEP). The

bus allows the 81341 and 81342 I/O Proce ssors to in terface to othe r I

C peripherals

and microcontrollers for system management functions. For more information, refer to

C Peripherals for Microcontrollers

(Philips Semiconductor)

2.1.10 UART Units

The 81341 and 81342 I/O Processors includes two UART units. The UART units allow

the two Intel XScale

proc e ss ors to serve a s a m as t e r and sl ave dev i ce residi ng on t he

UART bus. The UART units use a serial bus consisting of a two-pin interface. UART0

allows the 81341 and 81342 I/O Processors to interface to a console port for

debugging. Also refer to the National Se mico ndu ctor* 16550 device specificati on

2.1.11 Interrupt Controller Unit

Each Intel XScale

is ready to receiv e data. When the receiving UART deasserts

CTS#

high, the

transmitting UART must stop transmission to prevent overflow of the

receiving UART buffer. The

CTS#

signal is a modem-status input whose

condition can 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

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 th e transmitter. The user can program

the UART to interrupt the processor when DC TS changes state.

The programmer can then stall the outgoing data stream by

starving the transmit FIFO or disabling the UART with the IER

Note:

When UART transm ission is stalled by disabling the UART,

the user does not receive an MSR interrupt when CTS#

reasserts. This is because disabling th e UART also disables

interrupts. To work around this, the user can use Auto CTS

in Autoflow Mode, or program the CTS# pin to interrupt.

• Au toflow Mode:

In Autofl ow Mode, the UART transmi t ci rcuity checks the state of

CTS# before transmitting each byte. When CTS# is high, no

data is transmitted.

U0_RTS#

ActLow

Async

UART 0 Request to Sen d: This bit indicates to the remote device

whether the UART is ready to receive data. When this bi t is l o w , the

UART is ready to receive da ta. A reset operation se ts this signal to

its inactive (high) state. LOOP Mode operation holds this signal in

its inactive state.

• Non-Autoflow Mode:

The RTS# output signal can be asserted by setting bit[1] (RTS)

of the Modem Control Register to 1. The RTS bit is the

complement of the RTS# signal.

• Au toflow Mode:

RTS# is autom atically asserted by the autoflow circuitry when

the receive buffer exceeds its programmed threshold. It is

deasserted when enough by tes are removed from the buffer to

lower the da ta level back to the threshold.

U1_RXD

RTS# is automatically asserted by the autoflow circuitry when

the rec eive buffer exce eds it s programm ed thr esh old . It is

deasserted when enough bytes are rem oved from the buffer to

TCK

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.

TDI

Sync (T)

Test Data Input i s the JTAG serial i nput pi n. TDI is sampled on the

rising edge of TCK, during th e SHIFT-IR and SHIFT-DR states of

the Test Access Port. This signal has a weak internal pull-up to

ensure proper operation when this pin is not being driven.

TDO

Sync (T)

Rst (T)

Test Data Output is the serial output pin for the JT AG feature. TDO

is driv en on the falling edge of

TCK

during the SHIFT-IR and

SHIFT-D R states of the Test Access Port. At other times,

TDO

floats. The beh avior of

TDO

is independent of other resets.

TRST#

Async

ActLow

Test Re set asynchronou sly resets the Test Access Port controller

function of IEEE 1149 Boundary Scan Testing (JTAG). This pin has

a weak internal pull-u p.

Note:

This pin must be tied low when not used.

TMS

Sync (T)

Test Mode Select is samp led on the rising edge of

TCK

to select

the operation of the test logic for IEEE 1149 Boundary Scan

testing. This pin has a weak internal pull-up.

106 I/O No Connect: Pins have no usable function and must not be

connected to any signal, power, or ground.

P_RST#

Async

ActLow

Cold Reset is used to asynchronously reset the I/O processor

when it is low. This signal must be asserted whenever the power

supplies are outside of the specified ranges.

• Registers are reset to default values.

• Pins are driven to known states.

• Sticky configuration bits are reset.

WARM_RST#

Async

ActLow

Wa rm Reset is the sam e as a cold reset, exce pt sticky

configuratio n bits are not reset. Thi s pi n should onl y be used when

the sticky bit functionality is required. In this scenario, the

WARM_RST# pin must be tied to the syst em res et PC I_RST#

signal whi l e the P_RST# pin can be ti ed to the system po wer good

signal. If the sticky bit functionality is not required, the

WARM_RST# pin sh ould not be used and m u st be tied to Vcc.

When the PCI Express interface is used as an endpoint, the PCI

Express inband Hot Reset Mechanism can also be used to provide

the sticky bit functionality.

Note:

Driving WARM_RST# using any other methods than

suggested above may result in unpredictable behavior of

the device.

Notes:

1 = driven to V

0 = driven to V

X = drive n to unknown sta te

ID = The input is disabled.

H = pulled up to V

PD = pull-up disabled

L = pulled down to V

ODT = On Die Termination

GND = Tie to Ground.

EA = External Arbiter mode

IA = Interna l Arbiter mode

Z = output, pull-up/down disabled

VB = acts like a Valid Bidirectional pin

VO = a Valid Output level is driven.

VI = need to drive a Valid Input level.

AO = Analog Output level

AI = Analog Inpu t le vel

* = after power fail sequence completes

“-” = unaffected by this mode

a. MA[14] is only needed for 4GB memory support. When 4GB memory is not used this pin is NC.

Pin Requirements

To reduce clock jitter, the

CC1P2PLLD

CC1P2PLLP

, and

CC3P3PLLX

balls for the

phase-lock loop (PLL) circuits are isolated on the package. The low-pass filters, as

shown in the following figures, reduce noise-induced clock jitter and its effects on

timing relationships in system design.

This paragraph pertains to the

CC1P2PLLD

CC1P2PLLP

CC3P3PLLX

filters. The filter

components must be able to handle a DC current of 30 mA. Use a shielded type

inductor to minimize magnetic pic kup. The total series resistance from the board VCC

plane (before the filter) to the VCCPLL ball must be less than 1.5 ohm (including

component and trace resistance). The total series resist ance from the board VCC plane

(before the filter) to the top plate of the ca pac ito r mus t be greater than 0.35 o hm

(including component and trace resistance). The nodes connect ing VCCPLL and VSSPLL

to the capacitor must be as short a s pos sible (less than 0. 1 W ). VCC PLL and VSSPLL

must be routed close to each other to minimize loop area. The VSSPLL balls must be

connected to the filter only and not to any other ground, as shown in Figure 8 and

Figure 9. The inductor and capacitor must be placed close to each other. Any discrete

resistor must be placed between the VCC board plane and the inductor. I f the trace and

component resistance is high enough, a discrete resistor might not be required.

The bypass capacitor must be placed as close to the supply pins as possible. The series

impedances to both the supply pin and the PCB analog ground plane must be an order

of magnitude lower than the ESR and E SL specified for the capa citor.

the worst case data patterns and skew materi al at the fo l l owi ng worst case voltages: Vcc33 = 3.63 V,

Vcc18 = 1.89 V, Vcc12 = 1.24 V and ambient temperature = 55°C.

3. Icc Active (Thermal) value is provided for selecting the system thermal design power (TDP). This is

based on the following typical voltages: Vcc33 = 3.3 V, Vcc18 = 1.8 V, Vcc12 = 1.2 V and ambient

temperature = 55°C.

4. Th e Customer Reference Boards use a 1.2 V switching regulator for all the 1.2 V supplies (Vcc1p2,

Vcc1p2x, Vcc1p2e, Vcc1p2ae) and a 1.8 V switching regulator for all 1.8 V supplies: (Vcc1p8,

Vcc1p8e).
