SPICoder® SA01 UR5HCSPI-SA01  
Very Low-Power Keyboard Encoder and  
Power Management IC for H/PCs  
HID & SYSTEM MANAGEMENT PRODUCTS, KEYCODER® FAMILY  
PRELIMINARY  
DESCRIPTION  
FEATURES  
The SPICoder® SA01  
• SPI-compatible keyboard encoder  
and power management IC  
• Ideal for use with the Intel  
StrongARM™ processor  
• Patented technology for extremely  
low power consumption —  
typically less than 2 µA between  
3-5V  
• Offers overall system power  
management capabilities  
• Available in low-profile QFP  
package  
• Fully compatible with the  
Windows® CE keyboard  
specification  
UR5HCSPI-SA01, a member of  
Semtech’s KeyCoder® product  
family, is a keyboard encoder and  
power management IC designed  
specifically for handheld PCs  
(H/PCs), web phones and other  
systems that run Microsoft®  
Windows® CE and utilize the Intel  
StrongARM™processor.  
• Works in harmony with the power  
management modes of  
Windows® CE  
• Provides special modes of  
operation for H/PCs, including  
programmable “wake-up” keys  
• Scans an 8 x 14 matrix; controls  
discrete switches and LED  
indicators  
The SPICoder® SA01 offers several  
features necessary to H/PCs,  
including extremely low power  
consumption, real estate-saving  
size, and special keyboard modes.  
• Implements high-reliability two-  
way protocol  
• Compatible with “system-on  
silicon” CPUs for H/PCs  
APPLICATIONS  
The IC consumes an extremely  
small amount of power (less than  
2 µA at 3V) and provides the host  
system both power management  
and I/O flexibility, with minimal  
battery drainage.  
• Personal digital assistants (PDAs)  
• Wearable computers  
• Internet appliances  
• StrongARM™ handheld PCs  
• Windows® CE platforms  
• Web phones  
PIN ASSIGNMENTS  
Special keyboard modes and built-  
in power management features  
allow the SPICoder® SA01 to  
operate in harmony with the power  
management modes of  
Windows® CE, resulting in greater  
user flexibility, and longer battery  
life.

The IC scans, debounces and  
QFP  
encodes an 8 x 14 keyboard matrix.  
It communicates with the host over  
the SPI channel, implementing a  
high-reliability two-way protocol.  
The SPICoder® SA01 also offers  
programmable features for wake-up  
keys and general purpose I/O pins.
