GL892S
Overview

GL892S is an USB 2.0 OCCS Combo Card Reader Controller.

 

GL892S supports various types of 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 2TB), such as SDXC, ultra high speed memory cards, SD3.0 UHS-I.

 

GL892S support international standard ISO7816 for smart card/SIM card application, EMVCo for Contact Level 1 for Europay, MasterCard, and Visa and PC/SC 2.0 for computing environments.

 

GL892S support two configurations of LUN setting. Dual LUN configuration supports smart card and SD. Single LUN configuration supports smart card only.

 

The GL892S 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.
