USB2.0 SD/MMC/MS Card Reader Controller

SM370

Overview

The SM370 is a single chip image controller for USB 2.0 PC camera solution. It supports a CMOS image sensor with up to 2.0 megapixel resolution. The SM370 integrates the color process engine, JPEG compression, AC-Link/IIS audio interface, and high-speed USB 2.0 device controller. Featuring a built-in USB transceiver, Serial Interface Engine (SIE), and command decoder with full USB 2.0/1.1 support, the SM370 backs all systems equipped with legacy USB 1.1 host interface.

Diverse and flexible in function, the SM370 comes with an internal high-speed micro-processor, another set of built-in multi-function GPIO pins, and serial bus interface-in-chip. The SM370 also supports UVC (USB Video Class) under Windows® XP (Service Pack 2) and Windows® Vista environments, making it a convenient plug and play USB PC camera just like a USB disk. The SM370 is available in three package types: SM370M, 48-pin QFN package (6x6x0.8mm), SM370R, 48-pin LQFP package (9x9x1.6mm) and SM370Q, 64-pin LQFP package (9x9x1.6mm).
