STMicroelectronics announced their A3G4250D gyroscope. ST’s A3G4250D IC meets the AEC-Q100 industry-standard qualification for automotive integrated circuits. The 3-axis digital-output gyroscope is ideal for a range of automotive applications, including in-dash navigation, telematics and vehicle tolling systems. Samples of the A3G4250D angular-rate sensor are available now. Volume production will start by the second quarter of this. The ST A3G4250D gyroscope is priced at $6 each (for 1000-unit volume).
ST’s A3G4250D gyroscope features angular rates of up to +/-250dps (degree per second). An on-chip IC interface converts the angular-motion data into a 16-bit digital bit stream that is transmitted with high reliability to a dedicated microcontroller chip through a standard SPI or I2C protocol. The device provides two output lines (interrupt and data ready) and four user-selectable output data rates.
The 3V single-supply sensor integrates power-down and sleep modes and an embedded FIFO (first-in first-out) memory block for smarter power management. The A3G4250D embeds an 8-bit temperature sensor and operates within an extended temperature range from -40 to 85 degrees C. The device is robust to electromagnetic interference and withstands shocks up to 10,000g.
