GL3239
產品簡述

GL3239 is an USB 3.1 Gen 1 Card Reader Controller.

 

GL3239 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.

 

GL3239 support international standard ISO7816 for smart card/SIM card application, EMVCo for Contact Level 1 for Europay, MasterCard, and Visa, PC/SC 2.0 for computing environments and meet FIPS 201 requirements.

 

GL3239 support SPI interface which connect to NFC transceiver for NFC application.

 

The GL3239 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.
