USAR SPICoder SA UR5HCSPI-SA

A Semtech Company

USAR H/PC ICs family

Zero-Power Keyboard Encoder

& Power Management IC for

Intel StrongARM-based H/PCs

product specifications

Description

Features

• SPI-compatible keyboard encoder

and power management IC with

other interfaces available

• Fully compatible to the Windows

CE keyboard specification

The USAR SPICoder UR5HCSPI-

SA, a member of USAR’s H/PC ICs

family, is a keyboard encoder and

power management IC designed

specifically for Handheld PCs

• Works in harmony with the power

• Ideal for use with the Intel

management modes of Win CE

StrongARM processor

• Provides special modes of

operation for H/PCs, including

programmable “wake-up” keys

• Scans an 8 x 14 matrix and

controls discrete switches and LED

indicators

• Operates at patented Zero-Power

— typically consuming less than

2µA, between 3-5V

(H/PCs), Web Phones and other

systems that run Microsoft

Windows CE and utilize the Intel

StrongARM processor.

• Offers overall system power

management capabilities

• Implements high-reliability two-way • Compatible with “system-on silicon”

The UR5HCSPI-SA offers several

features necessary to H/PCs,

including low power consumption,

real estate-saving size, and special

keyboard modes.

protocol

CPUs for H/PCs

• Available in small 10mm by 10mm,

44-pin QFP package

Applications

The IC operates at Zero-Power

• Personal Digital Assistants (PDAs)

• Wearable Computers

• Internet Appliance

• StrongARM Handheld PCs

(less than 2µA @ 3V), providing the

the host system both power

management and I/O flexibility, with

minimal battery drainage.

• Windows CE Platforms

• Web Phones

Pin Assignments

Special keyboard modes and built-

in power management features

allow the USAR SPICoder SA to

operate in harmony with the power

management modes of Windows

CE , resulting in greater user

flexibility, and longer battery life.

The IC will scan, debounce and

encode an 8 x 14 keyboard matrix.

It communicates with the Host over

the SPI channel, implementing a

high-reliability two-way protocol.

The UR5HCSPI-SA also offers

programmable features for wake-

up keys and general purpose I/O

pins. The UR5HCSPI-SA is utilized

in several Intel reference designs.
