DESCRIPTION
GL835T is a crystal-less USB 2.0 to Single LUN SD3.0 (UHS-I/SDR-50) Memory Card Reader controller and targets for the application which require operating temperature -40°C to 85°C.
It supports USB 2.0 high-speed transmission to Secure DigitalTM (SD), SDHC, miniSD, microSD (T-Flash) on one chip. It also supports huge density memory cards (up to 2TB), such as SDXC and Memory Stick XC. As a single chip solution for USB 2.0 flash card reader, the GL835T complies with Universal Serial Bus specification rev. 2.0, USB Storage Class specification ver.1.0, and SD card interface specification.
The GL835T integrates a high speed 8051 microprocessor and a high efficiency hardware engine for the best data transfer performance between USB and flash card interfaces. Its’ pin assignment design fits to card sockets to provide easier PCB layout. Inside the chip, it integrates 3.3V to 1.8V regulators and power MOSFETs and it enables the function of on-chip clock source (OCCS) which means no external 12MHz XTAL is needed and that effectively reduces the total BOM cost.
