DESCRIPTION
FEATURES
The SH1475 single-axis capacitive
touch sensor controller is a cost-
effective, single-dimension
capacitive position analyzer with a
full-duplex SPI® interface. The
SH1475 is ideal for handheld
devices such as MP3 players.
The SH1475 uses an advanced
algorithm for enhanced motion
control interfacing PCB-based
capacitive sensor. The SH1475
includes a signal conditioning
circuit for a low cost, simple and
real estate-saving implementation.
Just a few additional low-tolerance
external components are needed
for a complete solution.
• Full-duplex SPI Interface
• PCB-based capacitive sensor
• Five switches
• 2.7 V – 5.5 V
APPLICATIONS
• Portable media players
• Portable media centers
PIN ASSIGNMENTS
• Low power consumption: 1 µA in
standby state (typical)
• Royalty-free and cost-effective
• Customization available
• Small 6 mm x 6 mm 36-lead
MLPQ package
• Instruments
• Cell phones
Typically consuming about 1 µA in
the standby state, the SH1475 is
ideal for battery-operated systems.

Host is awake or sleeping, SH1475 has data to send
1. SH1475 asserts nWakeUp.
45
2. Host asserts nChipSelect. If nChipSelect is low already, it will stay low.
3. SH1475 drives the MOSI and SCLK lines and sends the packet. Host may send a complete command packet,
or Host must keep MISO line static (or at least NOT send command packet sync pattern in the first byte).
4. SH1475 floats the MOSI and SCLK lines and de-asserts nWakeUp.
5. Host may de-assert nChipSelect and go to sleep.
