Freescale Semiconductor
3.2.1
A unique serial number is programmed into each device during manufacturing. The serial number is composed of the following
information.
Lot numbers begin at 1 for all devices produced and are sequentially assigned. Serial numbers begin at 1 for each lot, and are
sequentially assigned. No lot will contain more devices than can be uniquely identified by the 13-bit serial number. Not all allow-
able lot numbers and serial numbers will be assigned.
3.2.2
The Type Byte is programmed at final trim and test to indicate the axis of orientation of the g-cell and the calibrated range of the
device.
3.2.2.1
This bit denotes the low-pass filter characteristic.
0 - 400 Hz, 4-pole
1 - 180 Hz, 2-pole
3.2.2.2
Bit 6 is reserved. It will always be read as a logic ‘0’ value.
3.2.2.3
The AXIS bit indicates direction of sensitivity
0 - Z-axis
1 - X-axis
3.2.2.4
Bit 4 and Bit 3 are reserved. They will always be read as a logic ‘0’ value.
3.2.2.5
These three bits define the calibrated range of the device as follows:
