re: Six-axis sensor fuses accelerometer with magnetometer

I was wondering if anyone will be able to advise on which off-the-shelf magnetometer will be most sensitive.

ON the "Wiring up neuromorphic electronics" column, p27, the red text under the brain image has NEUROMOPHIC instead of neuromorphic......Ed

Freescale is on a catchup exercise here. Bosch and ST (and now InvenSense) have a bigger share of the market. The differentiations described in the comment above may help Freescale change some of that dynamic. MP Divakar

@R_Colin_Johnson: I think the differences you point out between Freescale and others (in 6-axis combo MEMS chips) are easy to catchup except for the TMR effect. Differentiations can also come from intelligent application of 3D IC packaging technologies which has potential to further reduce real estate requirements. MP Divakar

ST didn't have a magnetometer until recently. The LSM333D (announced in March) is a combo accelerometer, gyro, and magnetometer. I believe they worked with Honeywell on the magnetometer part. Also for magnetometers, don't forget AKM (Asahi Kasei Microdevices). Freescale still don't have a gyroscope, which is a pity.

ST might be leading with accelerometers but they don't have a magnetometer in their portfolio. Honeywell sensing were pioneers in the field of e-compasses followed by Philips/NXP with KMZ series about a decade ago. Now Freescale and Honeywell seem to be the only players in the field.

You're right -- we should eliminate or ignore competition. That would simplify component selection greatly.

Is anyone better than ST in this sector? I think they dominate the MEMS world by light years. Check their revenue. Freescale is largely also-ran.

Bosch and Invensense already had six-axis e-compass combo chips, but Freescale claims to have an edge with its in-package DSP functions for sensor fusion. Freescale also swears by its magnetometer which uses the tunnel magnetoresistance (TMR) effect, which is CMOS friendly and being developed for MRAM too (spun-off as Everspin in 2008), has built-in tamper resistance capabilities plus a FIFO stores the last 32 samples so the applicaiton processor can catch up on readings it might have missed.

To say that Andy Weir's The Martian is an exploration of math, Mars, and feces is a slight simplification. I doubt that the author would have any complaints, though.
