GL3232SX
USB 3.2 Gen1 to SD 4.0 and DDR275 Low Power Single-LUN Memory Card Reader Controller
GL3232SX is an USB 3.2 GEN1 to SD 4.0 Single LUN Memory Card Reader Controller.
GL3232SX supports various types of SD memory cards such as Secure DigitalTM (SD), microSD and miniSD. GL3232SX supports high density memory cards such as SDXC(capacity up to 2TB) and SDUC(capacity up to 128TB). GL3232SX supports UHS-II speed mode, 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 GL3232SX 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.
