Gyroscopic MEMs sensors for car navigation applications occupy 16 sq mm
Designed for car navigation systems, the XV4001 series of gyroscopic sensors can be ordered with either a 3-wire and 4-wire SPI digital interface or an I2C digital interface. Operating from 3.3V ±0.3V, the sensors combine small, stable, hammerhead-shaped QMEMS crystals with optimised Epson ICs. They also provide excellent temperature compensation, for better stability and accuracy over changes in temperature. In addition, Epson further increased reliability by providing these gyroscopes with a new self-test function that senses irregularities.
The XV4001 series consists of four models, with different interface and package tilt angle combinations for different integrations. The XV4001BD (SPI interface) and XV4001BC (I2C interface) have a package tilt angle of 0 degrees, they measure 5.0×3.2×1.3mm. The XV4001KD (SPI interface) and XV4001KC (I2C interface) have a package tilt angle of 20 degrees, their footprint is 6.0×4.8×3.3mm.
