NCS1012CAEPR2

NCS1012CAEPR2 is the production tape-and-reel ordering code (type NCS1012C in the ST datasheet order table) for an STMicroelectronics inertial sensor module in an HQFN-24 6 × 6 mm package, combining an x-axis gyroscope — with selectable full scales of ±125, ±250 and ±350 dps — with a low-g accelerometer sensing the y and z axes. The axis map is what distinguishes this variant and must drive the purchase decision: the gyroscope measures rotation about the x axis, which suits boards mounted on edge or designs whose primary rotation of interest is pitch or roll about that axis, while acceleration coverage sits in the yz plane. Putting the gyro and accelerometer in one HQFN device removes a second sensor package, a second interface and the alignment error between discrete parts — a real simplification for compact motion, tilt and vibration sensing nodes. Selection advice: the NCS1012 family is a variant matrix, not a single part — the sibling NCS1012BAEPR2 (also listed) puts the gyroscope on the z axis with xy low-g sensing instead, and other family types cover medium-g ranges, so match the full NCS1012CAEPR2 code to the axis allocation your mechanical design and firmware were built around, and verify ranges and interface settings against datasheet DS15267. Parameters verified against STMicroelectronics documentation.
