1 General Description
PinPoint® is a single-axis MEMS angular rate sensor
(gyro) capable of measuring angular velocity up to a
maximum of ±1,000º/s which has two output modes;
an analogue voltage signal which is linearly
proportional to angular speed, and a digital signal in
SPI® protocol. The choice of output mode; analogue
or digital, is determined by the user when connecting
it to the user’s host PCBA; details of the electrical
interface between PinPoint® and the host PCBA are
given in Section 7.
PinPoint® is available in two basic configurations, one
which will measure angular velocity about an axis
perpendicular to the plane of the host PCBA, referred
to as ‘in-plane’ sensing (Part Number CRM102.1) and
one which measures angular velocity about an axis
which is parallel to the plane of the host PCBA, referred
to as ‘orthogonal’ sensing (Part Number CRM202.1).
This datasheet relates to part number CRM202.1.
With a combination of CRM102.1 and CRM202.1 it is
possible for the user to measure angular rate of
multiple axes (e.g. any combination of pitch, yaw and
roll) from a single host PCBA.
PinPoint® (CRM102.1 and CRM202.1) is supplied as
a PCBA surface mountable LCC ceramic packaged
device. It comprises five main components; silicon
MEMS ring Sensor, Pedestal, ASIC, Package Base
and Lid. More details of the construction are given in
Section 13.
There are eight actuators / transducers distributed
evenly around the perimeter of the silicon MEMS ring.
Located about its primary axes are a single pair of
‘primary drive’ actuators and a single pair of ‘primary
pick-off’ transducers. Located about its secondary
axes (at 45° to the primary) are two pairs of ‘secondary
pick-off’ transducers see Figure 1.1.
The ‘primary drive’ actuators and ‘primary pick-off’
transducers act together in a closed-loop system to
excite and control the ring primary operating vibration
amplitude and frequency.
Secondary ‘pick-off’ transducers detect radial movement
at the secondary axes, the magnitude of which is
proportional to the angular speed of rotation and from
which the gyro derives angular rate.
More information about the principles of operation are
given in Section 13.
