GL3224
產品簡述

The GL3224 is an USB 3.1 Gen1 Dual/Single LUN card reader controller, it provides 2 LUNs (Logic Unit Number) which can support various types of memory cards, such as 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), MS PRO Micro in one chip. It also supports SDXC and Memory Stick XC high density memory cards (capacity up to 2TB) and high speed SD 3.0 UHS-I memory cards.

 

The GL3224 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 also integrates 5V to 3.3V and 3.3V to 1.2V regulators and power MOSFETs which can reduce system BOM cost.
