Introduction

AI Translation

GL3231 is a USB 3.1 GEN1 to dual SD 3.0 LUN memory card reader controller. It supports multiple types of SD memory cards, such as Secure Digital cards, SDHC, miniSD and microSD, MultiMediaCard, RS-MMC, MMCmicro, and MMCmobile. It also supports high-density memory cards (capacity up to 2TB), such as SDXC, Ultra High Speed cards, and SD3.0 UHS-I. GL3231 also supports SANDISK EXTREME 160 MB/s microSD UHS-I cards. GL3231 integrates a high-speed 8051 microprocessor and an efficient hardware engine to achieve data transfer performance between USB and various memory card interfaces. It supports ISP (In-System Programming) for firmware upgrades via the USB port from an external SPI flash. It integrates 5V to 3.3V and 3.3V to 1.2V regulators along with power MOSFETs to reduce system BOM cost. It also integrates a 5V to 1.2V DC-DC converter as an alternative to improve power efficiency.
