TEARDOWN - REVERSE COSTING
Yole Développement is pleased to publish the reverse costing report of the 3-Axis MEMS accelerometers LIS3DH and Apple A2L supplied by STMicroelectronics.
Available on STMicroelectronics portfolio, the LIS3DH is the first linear 3-axis accelerometer in the "nano" family. Packaged in a 3.0x3.0x1.0mm, the device features an ultra-low-power consumption that allows power saving functions in consumer applications.
Specifically made for Apple, the A2L 3-axis accelerometer shares the same silicon dies with the LIS3DH but is packaged in a smaller 2.0x2.0x1.0mm package. The A2L is featured in the Apple iPod Nano 6G.
Manufactured with the same THELMA process than the previous STM inertial sensors, the LIS3DH / A2L uses a new gold-gold thermocompression bonding process which allows the MEMS die area to be shrinked by a ratio of 2 compared to the previous linear 3-axis accelerometer (LIS331DLH). Cumulated with a shrinked ASIC die, the manufacturing cost of this new generation of "Nano" accelerometers has been seriously reduced to fit the price pressure of consumer applications.
