UR8HC007-001 Datasheet, PDF (12/18 Pages) Semtech Corporation – Input Device and Power Management Companion IC for Jupiter Devices

HID MANAGER
The UR8HC007 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
four functional blocks: the PS/2 Port
Manager; the Keyboard Manager;
the Pointing Device Manager; and
the Direct Port Manager.
The function of each Manager is
explained in full in the Juno^TM
Technical Reference Manual.
OTHER JUNO^TM SERIES MEMBERS
Other members of the Juno^TM series
of companion ICs offers advanced,
ergonomic control of an internal
pointing device. Enabled pointing
devices include touch pads, touch
screens or force sticks. If the
application requires an internal
pointing device, using a pointing-
enabled Juno^TM will eliminate the
need for a dedicated mouse
encoder IC.
KEYBOARD ENCODING
The UR8HC007-001 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 Juno^TM 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
UR8HC007-001.

GENERAL PURPOSE INPUT OUTPUT
The Juno^TM 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.
