GL3230
產品簡述

The GL3230 is an USB 3.1 GEN 1 Multi-LUN card reader controller, it provides 4 LUNs (Logic Unit Number) which can support various types of memory cards, such as CompactFlashTM, Micro Drive, Secure DigitalTM(SD), SDHC, miniSD, microSD (T-Flash), MultiMediaCardTM (MMC), RS-MMC, MMCmicro, MMCmobile, Memory StickTM (MS), Memory Stick DuoTM (MS Duo), High Speed Memory StickTM (HS MS), Memory Stick PROTM (MS PRO), Memory Stick PROTM Duo (MS PRO Duo), Memory Stick PRO-HGTM (MS PRO-HG) and MS PRO Micro. It also supports high density memory cards (Capacity up to 2TB), such as SDXC, ultra high speed memory cards, SD3.0 UHS-I and the latest high speed memory cards DDR200 micro SD card, SANDISK EXTREME® 160 MB/s microSD UHS-I CARD.

 

The GL3230 integrates a high speed 8051 microprocessor and a high efficiency hardware engine for the best data transfer performance between USB and various memory card interfaces. It supports Serial Peripheral Interface (SPI) for firmware upgrade to SPI Flash Memory via USB port. It integrates 5V to 3.3V and 3.3V to 1.2V regulators and power MOSFETs which can reduce system BOM cost. It also integrates 5V to 1.2V DC-DC as alternative to improve the power efficiency.
