88SE9230A1-NAA2C000

The 88SE9230A1-NAA2C000 is a specific variant of the Marvell 88SE9230 SATA Host Controller. This device is part of Marvell’s line of high-performance storage controllers, designed to add multiple SATA ports to systems via a PCI Express interface. This controller is often used in storage applications like NAS (Network Attached Storage), RAID configurations, and other embedded systems requiring reliable and scalable SATA connectivity.

Features of 88SE9230A1-NAA2C000:

1. SATA III Support:
– Supports SATA III (6 Gb/s) interfaces, along with backward compatibility for SATA II (3 Gb/s) and SATA I (1.5 Gb/s), enabling high-speed data transfer rates for connected drives.

2. 4-Port SATA Connectivity:
– Provides 4 SATA ports, allowing connections for multiple hard drives, SSDs, or optical drives, expanding the storage capabilities of the host system.

3. PCI Express 2.0 Interface:
– Uses a PCI Express 2.0 x2 interface, ensuring fast and efficient data communication between the controller and the host system, which is crucial for maintaining high throughput in storage applications.

4. Hardware RAID Support:
– Supports hardware RAID levels 0, 1, 10, and Marvell’s HyperDuo technology. This feature allows for performance optimization, data redundancy, or a combination of SSD speed and HDD capacity.

5. HyperDuo Technology:
– This proprietary technology creates hybrid storage by combining SSDs and HDDs. Frequently accessed data is automatically stored on the SSD for speed, while less frequently accessed data resides on the HDD, optimizing both performance and storage capacity.

6. AHCI Compliance:
– Fully compliant with AHCI (Advanced Host Controller Interface), enabling native command queuing (NCQ) and hot-plug capabilities. This compliance ensures broad OS compatibility and robust performance.

7. Advanced Power Management:
– Includes power management features such as support for staggered spin-up, which reduces power draw during startup, and hot-swap capabilities, allowing drives to be connected or disconnected without shutting down the system.

8. Low Power Consumption:
– Designed for efficient operation with low power consumption, making it suitable for both desktop and energy-sensitive embedded applications.

9. Embedded Processing:
– Integrates a microcontroller that handles RAID operations and other advanced features, reducing the processing load on the host CPU and enhancing overall system performance.

10. Package:
– Packaged in a lead-free, RoHS-compliant QFN package, suitable for high-density PCB layouts and minimizing the space required on add-in cards or integrated systems.
