Epson S4E5A0A0 Inertial Measurement Unit
At recent international trade shows Epson debuted the S4E5A0A0 Inertial Measurement Unit (IMU). An inertial measurement unit senses inertial motion consisting of angular rate sensors on three axes and accelerometers in three directions. IMUs are primarily used to measure and control the behavior of mobile objects.
The IMU includes triple gyroscopes and a tri-axis accelerometer, for six degrees of freedom. The gyroscope provides high accuracy and stability (±300 deg/s), while the accelerometer offers a dynamic range of ±3 G. It offers excellent angular rate measurement performance (angle random walk: 0.24deg/√hr) and stability (gyro bias instability: 6 deg/h). The device is also equipped with industry-standard SPI and UART interfaces.
This Epson component is suited to industrial applications in areas such as inertial motion analysis and control, motional analysis and control, moving object control, vibration control and stabilization, and navigation systems.
Now, the bad news. At $2,500 per chip, the S4E5A0A0 is targeted toward industrial applications. It will reportedly begin shipping in July.

No free samples? :P
Thankfully it’s not a FBGA package … I wouldn’t like to be the guy responsible for soldering that :) As a matter of curiosity what’s the record price of a solderable part? I never realized it could get so high until I saw the earlier post about the $600+ ADI IMU.
I’m assuming you mean commercially available- I don’t know but some unique research, aerospace, and military parts are probably in the millions
It’s like Analog Device’s ADIS1640x, but more stable expensive and has reduced temperature calibration range, and accelerometer dinamic range only +-3g against ADIS’s 18g. Even low profile ADIS16334 gives +-5g with cost about 450$.
But i’m interesting in detailed DataSheet on Epson’s device. If someone finds it PLEASE send it to me!!!
Pavel, I can arrange for the data sheet, please send me your contact information.

How do these top-of-the-range MEMS IMUs compare with the traditional mechanical/gyros ones? I read a book recently called ‘Digital Apollo’… many pages were spent discussing the Apollo IMU and it’s quirky limitations (the gimbal lock)… could these $$$ chips have replaced the Apollo IMU or are they still some way off?
