Key Features of the ASM1061 SATA III to PCIe Bridge

Der ASM1061 is a reliable and efficient SATA III to PCIe bridge chip that enables high-speed data transfer between SATA devices and PCIe-based systems. It supports SATA III (6Gbps) and PCIe 2.0, making it ideal for applications like storage expansions, add-in cards, or connecting SSDs to PCIe slots. With its low power consumption and compact design, the ASM1061 ensures smooth and fast data handling while minimizing energy usage. It also supports hot-plugging, making it convenient for users to connect and disconnect devices without powering down the system. Whether you’re looking to expand storage or add SATA devices to your PCIe-enabled system, the ASM1061 offers a solid solution.

ASM1061 Pinout

Using the ASM1061 Pinout

Der ASM1061 is designed to connect a SATA device to a PCIe bus. The PCIe_TX+ Und PCIe_TX- pins (Pins 3 and 4) handle outgoing data transmission, while PCIe_RX+ Und PCIe_RX- (Pins 5 and 6) are responsible for receiving data. Similarly, the SATA_TX+ Und SATA_TX- pins (Pins 7 and 8) transmit data to the SATA device, while SATA_RX+ Und SATA_RX- (Pins 9 and 10) receive data from the device. Ensure that the power supply (VDD) is connected properly to avoid malfunction, and the LED pin (Pin 11) is used to indicate the device’s operational status. Proper grounding and voltage levels are essential for optimal performance and preventing damage to the chip.

ASM1061 Equivalent Models

Here’s a comparison of equivalent SATA to PCIe bridge chips with similar packaging and features:

Substitution Tips

When replacing the ASM1061, make sure the SATA version Und PCIe version are compatible with your system. For example, the ASM1062 is a close alternative with similar features and is often used for similar low-power, hot-plug applications. If you need a faster PCIe connection, the JMB585 supports PCIe 3.0, providing higher throughput, but make sure your system supports PCIe 3.0. For more advanced RAID or storage system compatibility, consider the Marvell 88SE9215, which also supports RAID features but in a smaller package. Always verify the data rate Und package type to ensure they fit your design requirements.

ASM1061 Firmware

Der ASM1061 firmware plays a key role in managing the communication between the SATA devices and the PCIe bus. This firmware ensures that data is transferred efficiently by controlling the data flow and enabling features like hot-plugging. It’s crucial to ensure that the firmware is up to date to avoid compatibility issues with newer storage devices and ensure smooth operation. Firmware updates can be provided by the manufacturer, improving performance and adding new features to the chip.

ASM1061 SATA Controller

Der ASM1061 SATA controller is a highly efficient bridge that converts the SATA interface to PCIe, allowing devices like SSDs and hard drives to connect to a PCIe slot. It supports SATA III (6Gbps), ensuring fast data transfer speeds for modern storage solutions. The controller provides reliable performance for applications such as data storage, RAID configurations, and expansion cards. With its compact design and low power consumption, the ASM1061 is a great choice for integrating SATA devices into PCIe systems.
