PL2536   USB 2.0 to eMMC Bridge Controller


The PL2536 is a Hi-Speed USB 2.0 Multi-Partition eMMC bridge controller that can partition the eMMC card into 3 drive areas: CD-ROM, Public and Security drive. The capacity for each partition can be easily configured using the PL2536 MP Tool software. The Security partition can be locked and unlocked with a user password setting. For CD-ROM only application, the Public partition can be removed during MP configuration. Similarly, for generic USB flash disk application, the CD-ROM partition can also be removed. Customers can also program their own company and product information (VID/PID, Manufacturer name, Product name, and Serial Number strings) into the hidden area of the eMMC memory.

The PL2536 has a built-in MOSFET for eMMC cards power supply and built-in 5V to 3.3V/1.2V regulators. The PL2536 is crystal-less design that saves the system BOM cost.

The PL2536 complies with the USB specification Rev. 2.0 and USB Mass Storage Class specification Rev.1.0. The PL2536 is plug-and-play and no driver installation needed. The standard USB mass storage drivers are already built inside Windows, Mac OS, and Linux (kernel 2.4 above) operating systems including Windows 10 and Mac OS X versions.
