Atmel AT43USB324 is the First USB Multimedia Keyboard Controller to Receive USB-IF Certification.Business Editors/High-Tech Writers SAN JOSE, Calif.--(BUSINESS WIRE)--Feb. 8, 2001 Atmel(R) Corporation (Nasdaq:ATML ATML Automatic Test Markup Language ATML Automated Test Markup Language ) announced today that it has received certification from the Universal Serial Bus See USB. (hardware, standard) Universal Serial Bus - (USB) An external peripheral interface standard for communication between a computer and external peripherals over an inexpensive cable using biserial transmission. Implementers Forum, Inc. for its AT43USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. 324, keyboard controller. The AT43USB324 is the first USB Multimedia keyboard controller to receive such certification and thus can use the new USB logo. "With computers and their peripherals rapidly implementing the USB protocol, the keyboard is the most natural place to connect most commonly used peripherals such as the mouse, joystick, etc.," said Mahmoud Etemadi, marketing director for USB Products at Atmel Corporation. "We are convicted that our AT43USB324 is a product that can respond to this requirement. Because of its microcontroller based architecture, keyboard manufacturers and designers can easily change the features on their keyboards without resorting to hardware changes. Moreover, the AT43USB324 has been approved as a USB 1.1 compliant device by USB-IF and is presently listed on their Integrators List. Consequently, multimedia keyboards built using our AT43USB324 are guaranteed to be 100% USB 1.1 compliant. An Evaluation Kit, AT43DK324, is available to allow customers to evaluate this part." Internally, the AT43USB324 consists of a USB hub and function interface, a hub repeater, and an AVR (Automatic Voltage Regulation) See voltage regulator. RISE microcontroller. To the USB host, the embedded function appears as an attached port of the hub with its own device address and three endpoints. The third function endpoint makes the AT43USB324 extremely suitable for keyboards supporting the Consumer Page as described in the USB HID Usage tables. The AT43USB324 USB hub provides one attached and two external ports. Additionally, the AT43USB324 boasts of 16K of program memory, 512 bytes of SRAM See static RAM. SRAM - static random-access memory , 34 programmable I/O port pins, and 32 X 8 general working registers. It is very important to note also that AT43USB324 uses a 6 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. crystal to achieve a very low level of EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. emissions. The AT43USB324 comes in 48-pin LQFP See QFP. package and is currently in full production. In high volume, AT43USB324 is priced at $2.00. The price for the Evaluation Kit, AT43DK324 is $189.00.
