(Product: Electronic Compass)
[Title] 3-axis Electronic Compass IC
[Applications] Smartphones, Tablets, Wearable Devices, Games, Devices fo Augmented Reality or Virtual Reality
Description
Since the processing performance of portable appliances such as smartphones and tablets has been increasing, the market demand for power consumption to decrease is a critical point that has to be addressed. Asahi Kasei Microdevices Corporation (AKM) has launched the AK09915C to fulfill the markets demand for low-power and high-performance.
The AK09915C is a higher performing solution that is similar to its predecessor, the AK09912C, reducing power consumption of the host processor by adding FIFO function while keeping the package size the same. In addition, a variation of the AK09915C known as the AK09915D, has an open drain output on the DRDY pin (Interrupt, Push/Pull output for AK09915C) is also lined up.
[Features]
● The Electronic Compass with FIFO Buffer
The AK09915C has a 32-step FIFO buffer, which minimizes the load on the host processor reducing the number of interrupts by the electronic compass with FIFO. For example, system power consumption can be reduced using FIFO when executing a data logging that does not need a real-time response.
● Support 200Hz Output Data Rate (ODR)
The maximum supported frequency was 100Hz ODR with the AK09912C. The AK09915C supports 200Hz ODR frequency at the maximum which is suitable for applications that demands quick response, such as gaming applications.
● Low-Power Consumption Mode / Low-Noise Mode
The AK09915C has two drive modes: low-power and low-noise drive modes. In low-power mode, the consumption current can be suppressed by 10% compared with the AK09912C. In low-noise mode, measured noise will be reduced to half of that compared to the previous AK09912C. Additional noise reduction is available with a Noise Suppression Filter (NSF).
● One-chip Electronic Compass Architecture with Wide Measurement Range
The AK09915C inherits advanced characteristics from AKM’s established hall elements technology, like a wide measurement range. This wider measurement range makes the compass less sensitive to magnetic interference from other parts within the portable device, providing greater freedom in circuit design by enabling more flexibility in the placement of the compass on the printed circuit board.
The AK09915C consists of AKM’s exceptional one-chip electronic compass architecture with a 3-axis magnetic sensor comprising Si monolithic Hall elements and a magnetic concentrator. This provides inherently superior performance than a traditional multi-chip module configuration in which even slight orthogonal errors during module assembly have a critical effect. With the Si monolithic architecture, the Hall elements are manufactured directly on a single silicon substrate. Together with the magnetic concentrator, this enables mapping and assembly of this production using conventional semiconductor manufacturing equipment to maintain a stable supply of inventory even as demand grows rapidly.
