Keyboard Encoder &

Power Management IC for H/PCs

HID & SYSTEM MANAGEMENT PRODUCTS, H/PC IC FAMILY

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 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.
