JUNO FAMILY COMMUNICATIONS INTERFACE

The Juno™ family of controllers

implements two modes of serial

communications: The "Synchronous

Peripheral Interface" (SPI) mode

and the "Asynchronous Serial

Interface" (ASI).

The diagrams below describe the SPI and ASI communications interfaces,

respectively.

SPI Communications Interface

MOSI

MISO

The SPI is a synchronous bi-

directional, multi-slave interface that

supports bit rates up to 500 Kb/s.

Several Hosts and companion chips

implement the SPI protocol in order

to communicate with a wide range

of peripherals such as EEPROMs,

A/D converters, MCUs and other

system components. Alternatively,

the SPI may be implemented

through software on the Host side.

The Juno™ family implements the

_ATN as an additional hand-shake

signal in order to support low power

operation of the bus.

ASI Communications Interface

The ASI is an asynchronous

interface (UART type) that operates

at a fixed baud rate of 62.5 Kb/s.

Host

UR8HC007

Both interfaces are implemented

through the same set of four pins.

CTS

The IC determines the mode of

communication with the Host during

power-up by reading the value of

the SCLK/ISEL pin. If the pin is tied

low, the ASI mode is enabled. If it

is high, the SPI interface is enabled.

PROTOCOLS, COMMANDS AND REPORTS

Overview

General Message Structure

The Juno™ UR8HC007 implements

and supports four types of

transaction messages.

Communications between the Juno™ UR8HC007 and the Host processor

are implemented using a set of packet protocols and commands. The

general structure of a message is shown in the following diagram:

Message Body

to the Host system

(if applicable)

2. Commands from the Host system

3. Human Input Device (HID)

General Message Format

The Protocol Header identifies the type of transaction. The following table

lists the available protocols.

4. Event Alert messages to the

system

Protocol Headers

The protocol is fundamentally

implemented through a set of

general packet commands that

allow handling and reporting of

each individual controller register

and each bit within each register. In

this manner, the system achieves

maximum flexibility in manipulating

the operation of the UR8HC007

controller.

The Pointing Device Data Reports

support for MouseWheel-type of

For protocols used by either the host or the UR8HC007, a set of simple

commands is implemented. These support the basic communication

protocol and handle reset and errors in transmission.

A simple command would have the following structure:

The LRC is calculated for the

calculated by first taking the

bitwise exclusive OR of all bytes

from the message. If the most

significant bit (MSB) of the LRC is

set, the LRC is modified by

clearing the MSB and changing the

state of the next most significant

bit. Thus, the Packet Check Byte

will never consist of a valid LRC

with the most significant bit set.

POWER MANAGEMENT MODES OF OPERATION

POWER MANAGEMENT

The UR8HC007 has three modes of

operation relating to its power

consumption.

The Juno™ UR8HC007 family of controllers implements two power

management methods: system-coordinated power management and Self

Power Management™ (SPM).

The "Stop" mode is the lowest

System-coordinated power management primarily determines the tasks

performed and the type of reports communicated to the Host. The Juno™

monitors the system states through the PWROK (Power OK), _LID (Lid

closed) and _HSUS (Host suspended) lines. In addition to these signal

inputs, the UR8HC007 family provides a set of registers, described in the

power consumption mode. In this

mode, the crystal is stopped and

the IC consumes only 1 µA of

leakage current. This is the default

mode to which the IC will revert any

time an event or a signal condition

does not force it to exit this mode.

TM

"Registers" chapter of the Juno Technical Reference Manual, that can be

used by the host to control the PM-related performance of the controller

through software. According to the status of these lines (or register

settings), the Juno™ will enable or disable specific tasks and reports suited

to the current power and system management state of the Host.

The "Wait" mode is entered each

time it is necessary for a timer to be

running in order to perform a

system function. Such functions

include the LED blinking mode and

the use of one of the PWM

channels. Typical power

consumption in this mode is several

hundred µAs.

Self Power Management™ describes a method implemented by the Juno™

controller that, independently of any system intervention, results in the

lowest power consumption possible within the given parameters of its

operation. Through Self Power Management™, the Juno™ controllers are

capable of typically operating at only 1 µA, independent of the state of the

system. Self Power Management™ primarily determines the actual power

consumption of the controller IC.

The "Run" mode is entered briefly,

only to process an event or while an

interrupt-generating signal condition

persists. The controller IC will

remain in this mode only for as long

a signal prohibits it from reentering

a lower power consumption mode

or for as long as it is necessary to

process a Host-related transaction

(a few milliseconds).

The Juno™ implements the Semtech-patented Self Power Management™

method to achieve the minimum power consumption possible, independent

of the Host power management state.

Even when the Host is in the active state, the IC can still operate most of the

time at only 1 µA, even with external PS/2 devices attached to it.

ZERO-POWER OPERATION OF PS/2 PORTS

PS/2 PORTS

The Juno™ implements the

Semtech-patented "Message loss-

less wake-up™" method to operate

all three PS/2 ports. This method

enables the controller to interface

with devices attached to its PS/2

ports while still operating in the

"Stop" mode. Typical power

consumption of the PS/2 ports is

therefore 1 µA.

The UR8HC007-001 provides three PS/2 ports for the hot-plug connection of

an external keyboard, an external mouse and an internal mouse.

All of the internal and external devices are active at all times. Data from

both the external and internal keyboards and mice are merged and

seamlessly presented to the system.

5-Volt Tolerant PS/2 ports

The UR8HC007 controller can be powered by a power supply between 3

and 5 Volts (+/- 10%). Even when the USAR controller is powered by a 3-

Volt supply, the three PS/2 ports can directly interface with 5-Volt powered

devices — without the need of any external level-shifting circuitry. The Host

can enable or disable all the external PS/2 ports simultaneously, in sync with

the 5-Volt power plane that powers them. Alternatively, it can select any

PS/2 port selectively, through the "HID enable/disable control" register.

If a PS/2 device reports a data

packet, the controller will exit the

"Stop" mode for as long as it takes

to process the device message and

relay the information, if necessary,

to the Host system. This operation

is done transparently to the Host,

without any message loss or any

response delays from the input

devices.

PS/2 Mouse Handling

TM

The Juno provides a port for the connection of an internal PS/2 mouse.

This port supports MouseWheel functionality.

This unique technology allows

computers to operate at their

An internal mouse connected to a system’s PS/2 port consumes a significant

amount of power as it must always be “on.” A mouse connected to one of

Juno’s™ PS/2 ports consumes minimal power because the Juno™ will

power down even when the internal mouse is connected and active.

minimum power consumption state

even with PS/2 devices attached.

Systems that employ an internal

pointing device, such as a touch

pad or a force stick, can benefit the

most from this feature, since the

pointing device will force the

controller to exit its "Stop" mode only

when there is data to be reported.

POWER CONSUMPTION WHILE OPERATING THE PWM CHANNELS

Users should consider the built-in PWM channels for generating slowly changing DC control voltages. Since

continuous clocking is necessary for the PWM operations, the only penalty for using the built-in PWM channels is the

requirement for the chip to operate at least in the Reduced Power Mode, with typical Current Consumption of 750 µA.

D/A output of 0V, the Analog
