UR8HC007-001
Input Device and Power Management
Companion IC for Jupiter Devices
HID & SYSTEM MANAGEMENT PRODUCTS, H/PC IC FAMILY
DESCRIPTION
Juno
TM
01 is a member of a series of
multi-functional companion ICs for
Jupiter and other devices running
Microsoft
®
Windows
®
CE and
utilizing RISC-based processors.
The IC interfaces the system via
either asynchronous serial or the
Serial Peripheral Interface (SPI) and
provides keyboard scanning,
special general purpose I/O (GPIO)
and unique system power
management capabilities.
The Zero-Power
TM
Juno
TM
will power
down even between key presses.
Semtech’s proprietary circuitry
(patent pending) allows the IC to
power down even when PS/2
devices are connected and active.
Typical power consumption is less
than 1 µA, a first for embedded ICs.
The Juno
TM
provides continuous
operation between 3 and 5V and
scans a fully programmable 8 X 16
keyboard matrix. The IC is equipped
with three Zero-Power
TM
PS/2 ports
for the hot-plug connection of an
external PS/2 keyboard and mouse
as well as an internal PS/2 mouse,
including those with MouseWheels.
In addition, the Juno
TM
offers special
general purpose I/O (GPIO), ideal
for use for lid functions, power
switches, ring indicators, docking
signals, battery measurement, LEDs,
etc.
The integration of features, many of
them programmable, on one IC
increases flexibility and reduces
component count and cost.
FEATURES
• Typically consumes less than 1 µA
• Scans a fully programmable 8 X
16 matrix that supports Japanese,
English and European keyboards
• Operates continuously between 3
and 5 Volts
• Offers unique power management
capabilities that work in harmony
with Windows
®
CE’s power modes
• Always runs in “Stop” mode
without data or event loss
• Provides three Zero-Power
TM
PS/2
ports for the hot-plug connection
of external keyboards/mice &
internal mouse, including
MouseWheels
• Uses proprietary circuitry, so
“Stop” mode is entered even when
PS/2 devices are connected and
active
• Available in 1.7mm high package
to accommodate slim designs
PIN ASSIGNMENTS
• Jupiter devices/Professional PCs
• H/PCs, Web Phones, & G3
Terminals
• GPIO pins provide interrupt at
both falling and rising edge of
signals, ideal for lid functions,
power, ring indicators, docking
signals, battery measurement, etc.
• Has additional GPIO available for
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
• Cost-effective, reducing overall
system costs by integrating
features that would typically
require multiple additional
components
• Provides programmable features
that allow for maximum design
differentiation without
customization
• Other Juno
TM
versions offer control
of internal pointing device

In order to have a Negative Edge Interrupt capability for SW10 - SW17, the
corresponding Switch Inputs should also be connected to the extended resistive network
acting on the _WKUP pin. Switch closure must be tied to Ground; the IC will remain in high
power consumption mode until all the switches are released.
