Key Features
JM20336-LGAA4A is a highly integrated bridge controller built for storage interface conversion. It translates communication between USB 2.0 and SATA II 3.0G, so it works well in compact storage designs and interface adapter boards. In addition, the device supports dual-port SATA capability, which gives designers more flexibility in backup, cloning, and bridge-based storage systems. The integrated 15 MIPS 8051 core, 32K-byte mask ROM, and embedded 3.3V to 1.8V regulator also help reduce supporting component count. As a result, it is a practical choice for space-conscious designs that need stable USB-to-SATA communication.
Applications
External USB-to-SATA hard drive enclosures
Portable 2.5-inch SATA drive adapters
Drive docking stations
SATA storage backup devices
One-button disk copy systems
Embedded storage bridge boards
USB mass storage interface modules
Dual-LUN storage products
Industrial storage conversion hardware
Service and data recovery adapter tools
Product Overview
The JMicron JM20336-LGAA4A is designed for systems that need dependable bridging between USB and SATA storage interfaces. Because it supports USB 2.0 Hi-Speed operation and SATA II 3.0G communication, it fits many legacy and embedded storage platforms. Moreover, the controller supports SATA host or device configuration, which adds flexibility during hardware development. It also supports NCQ, hot plug capability, ATA and ATAPI packet commands, and USB Mass Storage Class Bulk-Only Transport operation.
This part is especially useful in products that connect SATA drives through USB without requiring a large controller design. Therefore, it works well in portable drive enclosures, cloning devices, and bridge modules used in support tools or industrial systems. The dual LUN capability further expands its usefulness in products that need more than one logical storage function over USB. In the same way, support for one-button copy and system backup functions makes it attractive for duplication and backup hardware.
Another advantage is its compact QFP64 package. That package helps engineers build smaller boards while still keeping the needed storage interface features. Likewise, the embedded regulator and onboard microprocessor simplify the surrounding design. For legacy storage products, repair tools, and specialized embedded hardware, JM20336-LGAA4A remains a practical bridge IC with a proven interface set.
