MS-3C
Magnetic field Sensor
„ Overview
YAS529 is the Triaxial Geomagnetic Sensor IC integrating buffer amplifier, A/D converter, clock generator,
and serial data interface circuit (supports I2C bus) on one chip package.
YAS529 allows you to make up a high sensitive, compact and low-power electronic compass in a portable
GPS system or a mobile phone.
„ Features
A manufacturing process that makes magnetic sensor on Si wafer with high precision realizes integration
with peripheral circuits on one chip.
High sensitive geomagnetic sensor IC is realized by integrating magnetic sensors and low noise
amplifiers.
High noise immunity is improved by digitizing output from geomagnetic sensor IC.
External interface supports I2C bus (100kbps/400kbps, slave mode).
Geomagnetic sensor with superior high board density and low-power consumption.
Automatic power-down control mode is available after geomagnetic measurements.
Three A/D input pins for an inclination sensor
Power-down control of an inclination sensor with a standby pin by the use of the General-Purpose Output
(GPO) Pin
Others.

Serial Data Interface
YAS529 serial data interface supports I2C bus serial interface and operates in the slave mode.
SCL (SCL)
: Serial clock input pin
SDA (SDA) : Serial data input/output pin
Communication is performed through the above pins.
General-Purpose Output (GPO) Pin
YAS529 has GPO as general-purpose output pin. This output pin can be used for
purposes such as power-down control of an inclination sensor with standby pin.
