JunoTM A4 UR8HC007-0A4
Zero-PowerTM Input Device and
Power Management IC
HID & SYSTEM MANAGEMENT PRODUCTS, H/PC IC FAMILY
DESCRIPTION
The JunoTM A4 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 A4 integrates
control of any 4-wire or 8-wire
resistive touch screen, keyboard
scanning, unique power
management capabilities, a direct
PS/2 port and plenty of General
Purpose Input / Output (GPIO).
The JunoTM A4 provides continuous
operation between 3V and 5V and
scans a fully programmable 8 X 16
keyboard matrix. The IC is
equipped with a direct Zero-PowerTM
PS/2 port for the hot-plug
connection of an external PS/2
keyboard or mouse.
The Zero-PowerTM JunoTM A4 will
power down even between key
presses. Proprietary circuitry
(patent pending) allows the IC to
power down even when the PS/2
device is connected and active.
Typical power consumption is less
than 1 µA, a first for embedded ICs.
FEATURES
• Typically consumes less than 1µA
• Scans an 8 x 16 keyboard matrix
that supports Japanese, English
and European keyboards
• Interfaces any four-wire 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
• Provides a direct Zero-PowerTM
PS/2 port for the hot-plug
connection of an external
keyboard or mouse
• Uses proprietary circuitry, so “Stop”
mode is entered even when PS/2
device is connected & active
• 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
• 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
APPLICATIONS
• Jupiter-class devices
• Professional H/PCs
• H/PCs
• Web Phones, G3 Terminals
PIN ASSIGNMENTS
The JunoTM A4 is equipped with a
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.
