Zero-Power
TM
Input Device and
Power Management IC
HID & SYSTEM MANAGEMENT PRODUCTS, H/PC IC FAMILY
DESCRIPTION
The Juno
TM
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 Juno
TM
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 Juno
TM
04 provides continuous
operation between 3 and 5V and
scans a fully programmable 8 X 16
keyboard matrix.The Zero-Power
TM
Juno
TM
04 will power down even
between key presses. Typical
power consumption is less than 1
µA, a first for embedded ICs.
The Juno
TM
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.
FEATURES
• Typically consumes less than 1µA
• Scans an 8 x 16 keyboard matrix
that supports Japanese, English
and European keyboards
• Interfaces any four- or eight-wire
resistive touch screen
• Operates continuously between 3
Volts and 5 Volts
• Offers unique power management
capabilities that work in harmony
with Windows® CE power modes
• Always runs in "Stop" mode without
data or event loss
• GPIO pins provide interrupt at both
falling and rising edge of signals,
ideal for lid functions, power, ring
indicators, docking signals, battery
measurement, etc.
APPLICATIONS
• Jupiter-class devices
• Professional H/PCs

• 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
• 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
accommodate slim designs
• H/PCs
• Web Phones, G3 Terminals
