... The following is the recommend printed circuit board (PCB) footprint for the HMC6343. All dimensions are nominal and in millimeters. Stencil Design and Solder Paste A 4-6 mil stencil and 100% paste coverage is recommended for the electrical contact pads. The HMC6343 has been assembled successfully with no-clean solder paste. . ...

... Off+) open circuited, or ground one connection node. Operational Modes The HMC6343 has three operational modes; Sleep, Standby, and R un. Sleep mode is defined as having the analog circuitry powered off, and has the lowest power consumption while power is applied to the VDD pins. Standby mode has the HMC6343 fully powered, but with no measurements performed and the processor is waiting for commands to perform ...

... The figure below shows pictorially the orientations. To permanently change orientation, poke EEPROM Operational Mode Register 1 (0x04) with the appropriate binary bits set for Level, Upright Edge (UE), or Upright Front (UF). The HMC6343 will operate in the selected orientation after a power-up or reset command. More on the EEPROM registers in the following sections. ...

... LSB in 0x0A. Variation Angle Correction The v ariation angle or declination angle of the HMC6343 is the number of degree that must be added to the internal compass heading to convert the magnetic north reference direction to the geographic (true) north reference direction. This angle information is provided to the HMC6343 from external latitude and longitude data processed through a World Magnetic Model equation to compute variation angle lookup table. Two EEPROM Bytes are used to store the variation angle, and the binary value is in tenths of a degree and in two’ ...

... The command protocol defines the content of the data (payload) bytes of I device (HMC6343). Note that angular outputs are in tenths of a degree (0-3600 heading, ±0-900 tilt). After the master device sends the 7-bit slave address, the 1-bit Read/Write, and gets the 1-bit slave device acknowledge bit returned ...

... HMC6343 Timing Upon power application to the HMC6343, wait nominally 500 milli-seconds before sending the first I2C command (typically a 0x32 byte followed by a 0x50 byte for the usual heading/pitch/roll). Depending on the command sent, a delay time should be inserted before clocking out the response bytes (send 0x33, clock back response bytes). The following table indicates the response delay times for various commands. Table 3 – ...

... Not Assigned User Hard-Iron Calibration The HMC6343 provides a user calibration routine with the 0x71 command permitting entry into the calibration mode and the 0x7E command to exit the calibration mode. After entering the calibration mode, rotate the device reasonably steady for 360 degrees about the Y (Left - Right) axis and then 360 degrees about Z (Up - Down) axis ...
