W83L518D
1. GENERAL DESCRIPTION
W83L518D is Winbond's innovative solution to a new class of storage devices for IA Noetebook,
Desktop PC and PC system-related products. It incorporates a security Application: Smart Card
Interface and two most promising compact storage interfaces: Memory Stick interface, and SD
Memory Card/Multimedia Card interface in IT era.
To cater boundless IT implementation possibilities, W83L518D can be configured to interface with
host through LPC bus. Base on the LPC interface, one Smart Card Interface port and two flash
memory interfaces - Memory Stick and SD Memory ports are provided. The kind of versatility allows
user to design very cost-effective products in a very flexible way.
The whole chip of W83L518D operates at voltage level of 3.3 V except Smart Card Interface port's I/O
pins that are at 5 V to be compatible with mainstream Smart Card implementations. Advanced power
management feature further optimizes power consumption whether in operation or in power down
mode.
W83L518D comes as a 48-pin LQFP streamline package. Combining with powerful functions,
effective power management, and versatile configurability, this integrated media reader offers a
perfect approach for design of storage device of IT products.
