记忆卡读卡器控制器-GL3224-QFN-32

GL3224 电子元器件 GENESYS/创惟科技 封装QFN-32 USB 3.0双/单LUN 记忆卡读卡器控制器

DESCRIPTION
The GL3224 is a crystal-less USB 3.0 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 SD3.0 UHS-I memory cards.
The GL3224 can be configured as single LUN to support e•MMC v4.5, 1/4/8bit data bus, High Speed SDR/ High Speed DDR/ HS200 mode, and it is compatible with e•MMC v5.0.
The GL3224 also provide small package QFN32 (5x5mm) to support single LUN: SD3.0 only for extreme small PCBA design
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.
