GL3232X

USB 3.2 Gen1 to SD 3.0 DDR275 Low Power Single-LUN Memory Card Reader Controller
GL3232X is an USB 3.2 Gen 1 to SD 3.0 Single LUN Memory Card Reader Controller.
 
GL3232X supports various types of SD memory cards such as Secure DigitalTM (SD), microSD and miniSD. GL3232X supports high density memory cards such as SDXC(capacity up to 2TB) and SDUC(capacity up to 128TB). GL3232X supports legacy UHS-I speed mode and further supports up to DDR275 speed mode with UHS-I interface to enhance the performance of reading and writing.
 
The GL3232X integrates a high speed 8051 microprocessor and a high efficiency hardware engine for the best data transfer performance between USB and SD memory card interface. It supports ISP (In System Programming) for firmware upgrade from the external SPI Flash via USB port. It also integrates LDO, DC-DC and power MOSFETs which can reduce the system BOM cost and improve power efficiency.
