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
Interface" (ASI).
The diagrams below describe the SPI and ASI 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.

ASI Communications Interface
The ASI is an asynchronous
interface (UART type) that operates
at a fixed baud rate of 62.5 Kb/s.

Both interfaces are implemented
through the same set of four pins.
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.
Please refer to the JunoTM 04
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™ UR8HC007-004
implements and supports four types
of transaction messages.
Communications between the Juno™ UR8HC007-004 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 IC to the
Host system
2. Commands from the Host system
to the IC
Protocol Header
Command/Report Identifier
Message Body
(if applicable)
LRC
3. Human Input Device (HID)
reports to the system
General Message Format
4. Event Alert messages to the
system
The Protocol Header identifies the type of transaction. The following table
lists the available protocols.
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 UR8HC007-004
controller.

General Commands Format
The Pointing Device Data Reports

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.

Simple Command Structure
Following is a summary of the simple commands used by both the Host
and the UR8HC007-004:
LRC (Longitudinal
Redundancy Check)
Simple Commands Summary
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™ 04 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 section
of the Juno™ 04 Technical
Reference Manual. The register
architecture of the Juno™ 04 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 Juno family 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™
04 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 04 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™ 04 will enable or disable specific tasks and reports
suited to the current power and system management state of the Host.
TM
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.
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™
family of controllers 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™ 04 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.

HID MANAGER
KEYBOARD ENCODING
The UR8HC007-004 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 UR8HC007-004 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 04 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
UR8HC007-004.

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 or force
sticks. If the application requires an
internal pointing device, using a
pointing-enabled JunoTM will
eliminate the need for a dedicated
mouse encoder IC.

GENERAL PURPOSE INPUT OUTPUT
The JunoTM 04 provides many GPIO pins which enable OEMs to easily
differentiate their products.
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.

can detect the configuration automatically at power-up and behave
properly for that configuration. The touch and motion qualities are exactly
the same for both configurations. For more details, see the analytical pin
descriptions for touchscreen in the "Pin information" chapter.
Touch detection
The Pointing Device Manager periodically checks whether there is touch on
touchscreen. If no touch is detected, the pointing device manager drives
the touchscreen into power saving mode. If a touch is detected,
touchscreen is forced into driving state and prepared for measurement.
Touch measurement
When the Pointing Device Manager detects a touch on touchscreen, it
drives the touchscreen into drive state and does measurement. If the
touch data is not good enough, the measured data are not used for the
algorithm. Only good touch data are used for the algorithm.
Touch algorithm
Due to hand shaking and electrical noise, the raw data can not be output
directly. The Pointing Device Manager uses a proprietary algorithm to
process the data.
Sampling rate
The sampling rate is 100 coordinate points per second.
Resolution
The maximum touchscreen resolution is approximately 1000 points per
direction. It varies with different touchscreens due to voltage drop on
connection wires.
Touchscreens from different manufacturers
Touchscreens from different manufacturers have different parameters. The
touchscreen parameters also depend on the size of touchscreen and
material from which it is made. Because the Pointing Device Manager
takes these properties into account, it can support almost any touchscreen.

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
Note 3:
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 4:
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 5:
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.
