GL3232S
USB 3.2 Gen1 to SD 4.0(DDR225) Single-LUN Low Power Memory Card Reader Controller
GL3232S is an USB 3.2 GEN1 to SD 4.0 Single LUN Memory Card Reader Controller.
GL3232S supports various types of SD memory cards, such as Secure DigitalTM (SD), SDHC, miniSD and microSD (T-Flash), MultiMediaCardTM (MMC), RS-MMC, MMCmicro and MMCmobile. It also supports high density memory cards (Capacity up to 128TB), such as SDXC and SDUC, ultra high speed memory cards, SD3.0 UHS-I and SD4.0 UHS-II card. GL3232 also supports SanDisk high-performance UHS-I SDXC up to 200MB/s of reading speed.
The GL3232S 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 ISP (In System Programming) for firmware upgrade from the external SPI Flash 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.
