Keyboard Encoder
and Power Management IC
Description
The UR5HCSPI-06 keyboard
encoder and power management
IC is designed specifically for
handheld PCs (H/PCs). The off-the-
shelf UR5HCSPI-06 will readily
work with CPUs designed for
Windows CE
廬
, saving OEMs
significant development time and
money as well as minimizing time-
to-market for the new generations
of handheld products.
Three main design features of the
UR5HCSPI-06 make it the ideal
companion for the new generation
of Windows CE
廬
-compatible,
single-chip computers: low-power
consumption; real estate-saving
size; and special keyboard modes.
鈥淨(jìng)uasi鈥?Zero-Power
TM
consumption
(less than 2碌A(chǔ) @ 3V), a must for
H/PCs, provides the host system
with both power management and
I/O flexibility, with almost no battery
drainage.
A unique package size of only
7mm x 7mm (the smallest 48-pin
package in the industry) fits the
tight space requirements of H/PCs.
Finally, special keyboard modes
and built-in power management
features allow the USAR
SPICoder
TM
06 to operate in
harmony with the power
management modes of Windows
CE
廬
, resulting in more user
flexibility and longer battery life.
The UR5HCSPI-06 also offers
programmable features for wake-
up keys and general purpose I/O
pins.
