RTS5116数据手册Realtek中文资料规格书

描述 Description

The RTS5116 is a high-performance USB 2.0 card reader controller that integrates a USB 2.0 PHY, an SIE (Serial Interface Engine), an 8051 MCU, a ROM, a RAM, and a memory card controller onto a single chip. It supports access to Memory Stick™, Memory Stick PRO™, Secure Digital™ and MultiMediaCard™. The built-in high-speed USB 2.0 device controller provides a 480Mbps transfer rate and offers backward compatibility with the 12Mbps USB 1.1 specification.
Designed with an enhanced power control circuit, the RTS5116 fully complies with USB power specifications for bus-powered devices. Confirming to the USB Mass Storage Class Specification, the RTS5116 provides \"plug and play\" convenience without any driver installation.
The external serial EEPROM interface provides flexibility in storing a USB Vender ID, a Product ID, and also other vender content such as product information, a revision level, a serial number, etc. The four-bit EEPROM interface can be programmed to function as general-purpose I/Os.
To reduce the BOM, the RTS5116 integrates 5V to 3.3V and 3.3V to 1.8V regulators. The RTS5116 also provides 2 built-in PMOS for power control of memory cards. With limited external components required, the 48-pin LQFP packaged RTS5116 provides an ideal cost/performance ratio for high-performance USB2.0 flash memory card reader/writer applications.
