The GL830 is a highly-compatible, low cost USB 2.0 / PATA to SATA bridge controller, which integrates
Genesys Logic own design high speed UTMI (USB 2.0 Transceiver Macrocell Interface) transceiver/receiver and Serial ATA PHY. As a one-chip solution which complies with Universal Serial Bus specification rev. 2.0 and Serial ATA specification rev. 2.6. There are totally 4 endpoints in the GL830 controller, Control (0), Bulk In (1), Bulk Out (2), and Interrupt (3). By complies with the USB Storage Class specification ver.1.0 (Bulk only protocol), the GL830 can support not only plug and play but also Windows Vista/ XP/ 2000/ ME default driver. The GL830 uses 25MHz crystal and slew-rate controlled pads to reduce the EMI issue.
GL830 provides four package types LQFP 48pin (7x7mm), LQFN 46pin (4.5x6.5mm), LQFP 64-pin (7x7mm) & LQFP 128-pin (14x14mm) for different target applications.
1. LQFP 48pin package provides basic USB to SATA bridge function to fit standard USB 2.0 high speed
storage class applications such as SATA HDD and ODD enclosure. It provides the best cost / performance solution in industry. In terms of cost, GL830 features on-chip 5V to 3.3V regulator and low pin count package to minimize overall system cost. In terms of performance, GL830 provides industry-leading data read / write speed and latency that powered by internal turbo 8051 micro processor. In terms of power consumption, GL830 features low-power mixed signal design to reduce silicon operating current. It also provides various power management options for system designer to reduce system level power consumption.
2. LQFN 46pin package provides the same function / performance as LQFP 48pin. GL830 features smaller silicon foot print and lower silicon operating temperature, which is perfect for mechanical limited PCB design.
3. LQFP 64pin provides an additional SATA differential pair that enables USB / E-SATA (External SATA) to
SATA function for HDD enclosures with both USB and E-SATA port. GL830 features on-chip SATA switch that
provides both E-SATA to SATA and USB to SATA data path in one single chip.
4. LQFP 128pin integrates USB, PATA and SATA interface into one single chip. PATA interface can be
configured as host or device that meet system requirement of various applications. For example, when
PATA is in device mode, GL830 can be connected to embedded system's legacy IDE port to serve as a
multi-IO bridge for USB and SATA connection. When PATA is in host mode, GL830 is a USB to PATA
and SATA bridge that enable concurrent data transfer on both USB to PATA and USB to SATA path.
