The USB hub has 3 downstream ports, one of which is permanently attached to the USB function. The USB function controller has its own device address and endpoints. In game controller applications, the two external downstream USB ports can be used to connect other devices such as headphones sets for voice commands of games, Flash memory modules, or any other USB device. The A-to-D converters have a minimum conversion time of 12 µs that together with the 12input channel should cover even the most demanding game controllers such as gamepads, joysticks and racing wheels. The two PWM outputs can be programmed for 8-, 9- or 10-bit resolution for applications requiring force feedback. The 27 general-purpose programmable I/O pins provide generous inputs for the various buttons and switches and LED indicators that are being used in increasing numbers in today’s game controllers. The USB hardware block consists of a USB transceiver, SIE, hub repeater, endpoint controllers, and an interface to the microcontroller. The USB hardware of the AT43USB355 supports the physical and link layers of the USB protocol while the transaction layer and hub controller functions must be implemented in the microcontroller’s firmware. If the application does not require a hub, it can be disabled. The AVR architecture was developed to be programmed in C efficiently and without loss in performance. There are two versions of the chip. The AT43USB355E has a SRAM program memory that is automatically loaded from an external serial Flash/EEPROM during power on reset.

The AT43USB355 uses the same program and development tools as the Atmel AVR microcontrollers including C compilers, macro assemblers, program debuggers/simulators, incircuit emulators. A development kit is also available including firmware source code for the most common USB applications. 2 AT43USB355 Packaging Information 64AA LQFP Dimensions in Millimeters and Inches Controlling Dimensions Millimeters JEDEC STANDARD MS-026 ACB AT43USB355 PIN 1 ID PIN 1 1121..2755 00..449623 SQ 190..9100 00..338997 SQ MAX TITLE 2325 Orchard Parkway 64AA, 64-lead, Low-profile mm Plastic Quad Flat R San Jose, CA 95131 Package LQFP 64AA Atmel Headquarters Corporate Headquarters 2325 Orchard Parkway San Jose, CA 95131 TEL 1 408 441-0311 FAX 1 408 487-2600 Europe Atmel SarL Route des Arsenaux 41 Casa Postale 80 CH-1705 Fribourg Switzerland TEL 41 26-426-5555 FAX 41 26-426-5500 Asia Atmel Asia, Ltd.
