SM333
Adheres to Universal Serial Bus Specification Revision 2.0
USB2.0 Multi-LUN Universal Flash Memory Card Reader Controller
Adheres to USB Mass Storage Class Bulk-only Transport
specification v1.0
Overview
Supports high-speed (480Mbps) and full-speed (12Mbps)
data transmissions
The SM333, a high performing USB2.0 Flash memory
card reader controller, is compatible with most up to
date CF4.0, SDHC (SD2.0), MMC4.2, MemoryStick
Pro, xD1.2 and SmartMedia. All Flash memory card
host interfaces utilize the maximum data transmission
rate. Furthermore, when working with external serial
EEPROM, the SM333 is firmware upgradeable using the
SMI In-System-Programming (ISP) tool. This ISP feature
markedly reduces external firmware upgrade costs, and
stores product vendor ID and product information in the
same EEPROM space.
Flash Memory card supports:
- CompactFlash™ (CF) Card
• CF v1.0/v2.0/v3.0/v4.0 specifications
• PIO mode 0-6 and Ultra DMA mode 0-6
• CF Type I and Type II
- MicroDrive (MD)
- Secure-Digital™ (SD) v1.0/ v1.1/ v2.0
• SDHC, SD, Mini SD™ and Micro SD™
- Multi-Media Card™ (MMC) specification
v3.x/v4.0/v4.1/v4.2
• MMC, High-Speed Multi Media Card™ (HS-MMC),
RS MMC, MMC Micro and MMC-mobile
Equipped with high-integration 0.16µm process
technology, the SM331 built-in PowerMost FETs for
memory card power and 3.3v/1.8v regulators for core
logic and memory card power to lower material costs. The
built-in Voltage Drop Detector (VDT) protects the SM333
if a damaged Flash memory card is inserted.
- Memory Stick™ (MS)
• Memory Stick Duo™ (MS DUO), Memory Stick Pro™
(MS PRO), High Speed Memory Stick™ (HS-MS),
Memory Stick Pro Duo™ (MS Pro Duo), MS Pro Micro
and Memory Stick ROM
• MSpro-HG
• Memory Stick 1-/4-bit modes
- xD-Picture™ card (xD) v1.0/v1.1/v1.2
• H-Type
The SM333 is driverless compatible with most common
operating systems, including Windows Vista, XP, 2000,
ME, WinCE5.0, MAC10x and Linux Redhat This Flash
memory card reader is supported by the SMI vendor driver
under Windows98 and 2000 SP1/SP2. The SM333 is
optimized for system communication with Flash memory
media, and is appropriate for either standalone card reader
stations or embedded systems such as desktop and laptop
PCs, game consoles, LCD TVs and photo printers.
