MEMS Accelerometer Sets Size And Cost Benchmarks

 Roger Allan, Contributing Editor

Thanks to its patented thermal heated-gas principle of measuring acceleration and the use of novel ball-grid-array (BGA) and wafer-level packaging (WLP), the MEMSIC MXC626Xc breaks records in size and cost. The two-axis, ±2-g (X/Y) accelerometer produces an 8-bit digital output in a tiny package that measures 1.2 by 1.7 by 1.0 mm at a single-unit OEM price of just 35 cents ($0.35).
