Product Overview
The JMD330-LGAA1D is JMicron’s single-chip SATA Gen1 to PATA/IDE storage bridge IC. It uses pure hardware logic to translate SATA host signals for legacy IDE HDDs, SSDs and ATAPI optical drives, with plug-and-play operation without extra drivers. Supporting full PIO/DMA/Ultra DMA 133 modes, it integrates an 8KB bidirectional FIFO buffer and stable SATA PHY. Packaged in compact TQFP-64 with low-power design, this commercial-grade chip serves legacy storage upgrades, external optical drive enclosures and industrial embedded interface conversion.
Core Advantages
Pure Hardware SATA-to-PATA Transparent Conversion
All protocol conversion is completed by on-chip hardware logic without any driver or firmware setup, realizing fully transparent SATA Gen1 to PATA/IDE signal bridging with broad cross-system compatibility.
Full ATAPI Peripheral Compatibility
Supports standard ATA hard disks, SSDs and complete ATAPI packet command sets, perfectly compatible with CD-ROM, DVD-ROM, DVD-RW and tape storage devices.
Low Power & Stable Continuous Operation
Optimized clock gating and low-voltage circuit design effectively reduce power consumption and heat output, suitable for long-term stable operation in compact embedded equipment.
Complete PATA High-Speed Transfer Support
Covers all mainstream transmission standards including PIO mode 0-4, Multi-Word DMA 0-2 and Ultra DMA 33/66/100/133, realizing stable maximum transmission bandwidth of 150MB/s.

Frequently Asked Questions
Q1: Is your currently available stock of the JMD330-LGAA1D bridge controller 100% genuine and original?
A: Yes, we guarantee that all JMD330-LGAA1D integrated circuits in our warehouse are 100% brand-new, factory-original components directly from JMicron Technology Corporation. Every batch passes internal tracking audits and is shipped inside secure anti-static protective packaging to keep the QFP leads pristine.
Q2: Does the JMD330-LGAA1D require custom firmware or a special software driver to connect IDE drives to SATA motherboards?
A: No, it does not. The JMD330-LGAA1D features automatic hardware conversion on the silicon die. It converts SATA host signals to PATA/IDE signals natively; legacy IDE/PATA or ATAPI drives are recognized as standard SATA devices by the system. No custom drivers, software utilities, or code installations are needed.
Q3: Can the JMD330-LGAA1D support ATAPI devices like optical DVD recorders or is it limited to hard drives?
A: This chip fully supports both standard ATA hard drives, SSDs and ATAPI optical peripherals. It completely parses and converts ATAPI packet commands, supporting normal reading and writing of CD/DVD optical drives and tape storage equipment.
Q4: How can our technical engineering division request a comprehensive component data sheet or bulk volume quotes?
A: Please complete the Quick Inquiry web form found directly on this webpage. Our technical support representatives will review your project requirements and respond with complete data packages and custom commercial pricing within 24 hours.
