JUNOTM FAMILY COMMUNICATIONS INTERFACE
The Juno™ family of controllers
implements two modes of serial
communications: The "Synchronous
Peripheral Interface (SPI) mode and
the asynchronous serial mode.
The diagrams below describe the SPI and asynchronous communications
interfaces, respectively.
SPI Communications Interface
The SPI is a synchronous bidirectional, 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.

Asynchronous Serial Communications Interface
The asynchronous serial mode
interface (UART type) operates at a
fixed baud rate of 62.5 Kb/s.
Both interfaces are implemented
through the same set of four pins.
Host
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 asynchronous serial mode
is enabled. If it is high, the SPI
mode is enabled.
Please refer to the JunoTM Technical
Reference Manual for a description
of handshake and critical timing
parameters for each interface.

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:
1. Commands from the UR8HC007
to the host system
Protocol Header
Command/Report Identifier
Message Body
(if applicable)
2. Commands from the host system
to the UR8HC007
LRC
3. Human Input Device (HID)
reports to the system
4. Event Alert messages to the
system
General Message Format
The protocol header identifies the type of transaction. The following table
lists the available protocols.
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.

General Commands Format
The pointing device data reports
format covers both absolute (where
applicable) and relative positioning
devices. In addition, it provides
support for MouseWheel-type of
input devices.
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.
Keyboard Data Report
The keyboard data reports return
changes on the keyboard matrix or
the external PS/2 keyboard device.
Keys are uniquely identified
according to the key number table
listed in Appendix A of the JunoTM
Technical Reference Manual. The
Key Up or Key Release number is
the result of a logical OR of the key
number with 80H.
LRC (Longitudinal
Redundancy Check)
A simple command would have the following structure:

The LRC is calculated for the
whole packet, including the
protocol header. The LRC is
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.

REGISTERS
The Juno™ implements a set of
internal registers that can be used
to control and monitor the
operation of the various functional
units of the controller IC. These
registers can be accessed through
the Read/Write register commands
described in the Commands
chapter of the Juno™ Technical
Reference Manual. The register
architecture of the Juno™ allows
for maximum flexibility and
expandability of the controller
operation. At the same time, by
using the default values for each
register, a system can utilize all the
basic functionality of the IC
controller with minimum host driver
intervention.

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
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.
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
"Registers" chapter of the JunoTM 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 µA.
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).
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 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.

SPM
ZERO-POWERTM OPERATION OF PS/2 PORTS
The Juno™ implements the
Semtech-patented "Message lossless 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.
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.
This unique technology allows
computers to operate at their
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.
Copyright ©1998-2001 Semtech Corporation
DOC8-007-001-DS-109
PS/2 PORTS
The UR8HC007-001 provides three PS/2 ports for the hot-plug connection of
external keyboards, external pointing devices, and an internal pointing
device.
All of the internal and external devices are active at all times. Data from
external and internal devices 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
Volts and 5 Volts (+/- 10%). Even when the 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.
PS/2 Mouse Handling
The JunoTM provides a port for the connection of an internal PS/2 pointing
device. This port supports MouseWheel functionality.
A pointing device connected to a host system’s PS/2 port consumes a
significant amount of power as it must always be “on.” A pointing device
connected to one of Juno’s™ PS/2 ports consumes minimal power because
the Juno™ will power down even when the pointing device is connected
and active.

HID MANAGER
The UR8HC007 Human Input
Device (HID) Manager is
responsible for the configuration
and handling of HID devices that
are embedded or attached to the
controller. The HID Manager has
the following responsibilities:
1. Enabling and disabling
embedded and attached input
devices through the "HID
enable/disable control" register
2. Formatting and relaying input
device reports to the host
3. Controlling the configuration and
operation of both embedded and
attached input devices
The HID Manager consists of four
functional blocks: the PS/2 Port
Manager; the Keyboard Manager;
the Pointing Device Manager; and
the Direct Port Manager.
The function of each Manager is
explained in full in the JunoTM
Technical Reference Manual.
OTHER JUNOTM SERIES MEMBERS
Other members of the JunoTM series
of companion ICs offers advanced,
ergonomic control of an internal
pointing device. Enabled pointing
devices include touch pads, touch
screens or force sticks. If the
application requires an internal
pointing device, using a pointingenabled JunoTM will eliminate the
need for a dedicated mouse
encoder IC.

DOC8-007-001-DS-109
KEYBOARD ENCODING
The UR8HC007-001 will encode an 8-row by 16-column keyboard matrix.
OEMs may reprogram the matrix by sending commands to the IC from the
system. The JunoTM supports English, Japanese and European keyboards.
In addition, the IC supports both sticky keys and notebook-style keyboards.
The keyboard below, the Fujitsu FKB7654, is the default keyboard for the
UR8HC007-001.

GENERAL PURPOSE INPUT OUTPUT
The JunoTM provides many GPIO pins which enable OEMs to differentiate
their products easily.
Four GPIO ports provide interrupt at both falling and rising edge of signals.
Two of these pins are dedicated for use as a lid indicator and digital power
monitor. The other two may be used for a ring indicator, docking signal, soft
power button, etc.
Three GPIO pins provide A/D input and are ideal for battery measurement.
Three GPIO pins provide two pulse width modulation (PWM) channels and
one D/A channel and may be used for analog control functions such as
LCD brightness/contrast or audio volume control.
Four GPIO pins with high drive ability are set aside as LED drivers or I/O.
Eight GPIO pins can be used as system control outputs or inputs, for
example, for switches.

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.
NOTES FOR ELECTRICALS
Note1:
Current Consumption values do not
include any loading on the Output
pins or Analog Reference Current
for the built-in A/D or D/A modules.
Note 2:
Since the built-in A/D module
consumes current only during short
periods of time (when A/D
conversion is actually requested),
the Analog Reference Current for
the built-in A/D module is not a
significant contributor to the overall
power consumption.
Note 3:
The Analog Reference Current for
the built-in D/A module correlates
linearly to the Output Voltage. For
D/A output of 0V, the Analog
Reference Current is null. For D/A
outputs approaching Full Scale
(AVREF), the maximum Analog
Reference Current is indicated in
this Table. This current is a
significant contributor to the overall
power consumption.
