USB224X
Ultra Fast USB 2.0 Multi-Format, SD/MMC, and MS Flash
Media Controllers
Highlights
The Microchip USB224x is a USB 2.0 compliant, Hi-
Speed bulk only1 mass storage class peripheral con-
troller intended for reading and writing to popular flash
media from the xD-Picture CardTM (xD)2, Memory
Stick® (MS), Secure Digital (SD), and MultiMedia-
CardTM (MMC) families.
The USB224x is a fully integrated, single chip solution
capable of ultra high performance operation. Average
sustained transfer rates exceeding 35 MB/s are possi-
ble if the media and host can support those rates. The
USB2244/44i includes provisions to read/write secure
media formats.

USB224X
1.0 INTRODUCTION
The Microchip USB224x is a flash media card reader solution fully compliant with the USB 2.0 specification. All required
resistors on the USB ports are integrated into the device. This includes all series termination resistors on D+ and D–
pins and all required pull-down and pull-up resistors. The over-current sense inputs for the downstream facing ports
have internal pull-up resistors.
1.1 Hardware Features
• Single chip flash media controller in low pin count 36-pin QFN, RoHS compliant package
• Commercial temperature products support 0°C to +70°C: USB2240/41 and USB2244
• Industrial temperature products support -40°C to +85°C: USB2240I/41I and USB2244I
• 8051 8-bit microprocessor
- 60 MHz - single cycle execution
- 64 KB ROM |14 KB RAM
• Supports a single external 3.3 V supply source; internal regulators provide 1.8 V internal core voltage for addi-
tional bill of materials and power savings
Compliance with the following flash media card specifications:
• Secure Digital 2.0
- HS-SD and SDHC
- TransFlash™ and reduced form factor media
• MultiMediaCard 4.2
- 1/4/8 bit MMC
• Memory Stick 1.43
• Memory Stick Pro Format 1.02
• Memory Stick Pro-HG Duo Format 1.01
- Memory Stick, MS Duo, HS-MS, MS Pro-HG, MS Pro
• Memory Stick Duo 1.10
• xD-Picture Card 1.2
1.2 Software Features
• If the OEM is using an external EEPROM, the following features are available:
- Customizable vendor, product, language, and device ID’s
- 12-hex digits maximum for the serial number string
- 28-character manufacturer ID and product strings for the flash media reader/writer
- LED blink interval or duration
