uALFAT

uALFAT, pronounced micro ALFAT, is is a full FAT32 file system stack that is embedded in a powerful 32-bit processor. ALFAT saves files and directories on medias in the standard FAT32 file system format so that the media can be accessed from any other devices that supports FAT32 file system, example a PC, most digital cameras and MP3 players. Simply, send your data to the uALFAT chip using a serial port, SPI or I2C and ALFAT will save your files on MMC or SD.
Key Features
- FAT32 support.
- Runs with simple robust protocol on UART, SPI or I2C.
- 256-byte FIFO for UART, SPI and I2C.
- UART runs as high as 921.6 K-baud, SPI clock is up to 7Mhz and I2C clock up to 400Khz.
- Fast file Write, up to 200 KB/S, average is 35 KB/S. (KB = 1024 Bytes).
- Fast file read, up to 700 KB/S.
- Can be easily used with any microcontroller including PIC, AVR.
- Supports Multi Media Card (MMC) and Secure Digital (SD) memory cards.
- Supports directories and subdirectories.
- Can open up to 4 files at the same time using file handles.
- Field upgradeable firmware.
- Firmware can be updated from a file on the connected media!
- Built in 10-bit ADC.
- All I/O pins are 5 volt tolerant.
- Very few external components are needed.
- Small LQFP 48 package.
- 40 to 60 mA, power consumption with capability of a complete shut off.
- -40°C to +85°C temperature operating range.
- Saves time and money and adds a great feature to your product!
Applications
- Data Logger.
- Picture viewer.
- MP3 players.
- Digital cameras.
- Automated machines.
Note the uALFAT is due for release late in March 2006 and all the information is preliminary.
USBwiz

Thanks to USBwiz ("the USB Wizard"), you can now easily add an USB keyboard, mouse, joystick or even printer to your system. USBwiz also includes a FAT file system so that you can run USB thumb drives and external USB (FAT formatted) hard drives. No USB knowledge is necessary, it is as simple as Plug and Play! Using simple commands via the UART, SPI or I2C interface, you can read/write files from your thumb drive or SD/MMC card. Accessing USB Human Interface Devices (HID) and USB printers is also just as simple.
Key Features
- FAT32, FAT16 and FAT12 support.
- Multi Media Card (MMC) and Secure Digital (SD) memory cards.
- USB host stack and raw access to USB devices.
- HID USB class support.
- Printer USB class support.
- Mass storage USB class support. Connect external hard drives or thumb drives.
- Easily used with any microcontroller including PIC and AVR.
- Runs with simple robust protocol on UART, I2C or SPI.
- UART runs as high as 921.6 K-baud, SPI clock is up to 7Mhz and I2C clock up to 400Khz.
- Field upgradeable firmware.
- Firmware can be updated from a file on the SD card or a thumb drive.
- Small LQFP 64 package.
- 40 to 50 mA, power consumption with low power mode.
- Single supply 3.3V.
- 5V tolerant I/O pins.
- -40°C to +85°C temperature operating range.
Applications
- Data Logger.
- Picture viewer.
- USB thumb-drive MP3 player.
- Digital camera.
- Automated machine.
- Keyboard/Mouse/Joystick interface.
- RS232 to USB-printer server.
