JunoTM 04 UR8HC007-004
Zero-PowerTM Input Device and
Power Management IC
HID & SYSTEM MANAGEMENT PRODUCTS, H/PC IC FAMILY
DESCRIPTION
The JunoTM 04 is a member of a
series of input device and power
management companion ICs for
RISC-based portable systems. On
a single IC, the JunoTM 04 integrates
control of any 4-wire or 8-wire
resistive touch screen, keyboard
scanning, unique power
management capabilities, and
plenty of General Purpose Input /
Output (GPIO).
The JunoTM 04 provides continuous
operation between 3 and 5V and
scans a fully programmable 8 X 16
keyboard matrix.The Zero-PowerTM
JunoTM 04 will power down even
between key presses. Typical
power consumption is less than 1
µA, a first for embedded ICs.
The JunoTM 04 is equipped with
Semtech’s proprietary protocol
developed specifically for RISC-
based handheld machines. It
interfaces the system via either
Asynchronous Serial (UART) or the
Serial Peripheral Interface (SPI).
The integration of features, many of
them programmable, on one IC
increases flexibility and reduces
component count and cost.

• Scans an 8 x 16 keyboard matrix
that supports Japanese, English
and European keyboards

LEDs, switches, etc.
• Offers internal control of LCD
brightness/contrast, audio, etc. as
well as four 10-bit A/D channels
for power management monitoring
• Provides programmable features
that allow for maximum design
differentiation without
customization
• Cost-effective, reducing overall
system costs by integrating
features that would typically
require multiple components
• Available in 80-pin 13 x 13 mm,
1.7mm high package to

HID MANAGER
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 HID Manager consists of the
two functional blocks: the Keyboard
Manager and the Pointing Device
Manager.
KEYBOARD ENCODING
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.

The function of each Manager is
explained in full in the JunoTM 04
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 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.
