Description
The Atmel AT43USB351M is a USB AVR-based microcontroller that is configurable as
a low-speed or full-speed USB device. Its program memory is a 24-Kbyte mask pro-
grammable ROM and its data memory is 1-Kbyte SRAM. The on-chip peripherals
consists of 19 general-purpose I/O ports, two timer-counters, SPI serial interface, a
PWM and a 10-bit AD converter with 12 input channels.
The MCU of the AT43USB351M is a high performance 8-bit AVR RISC that operates
at a clock frequency of 1.5 MHz, 12 MHz or 24 MHz. The A-to-D converter has a min-
imum conversion time of 12 μs that together with the 12 input 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 19 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 function has one control endpoint and four additional programmable end-
points, each with their own FIFOs. Two of the endpoints have a 64-byte FIFO each,
while the other two have 8-byte FIFOs. The USB hardware supports the physical and
link layers of the USB protocol while the transaction layer function must be imple-
mented in the MCU's firmware. The AVR architecture was developed to be
programmed in C efficiently and without loss in performance.
The AT43USB351M is binary-compatible with the AT43USB355. Program develop-
ment and debugging for the AT43USB351M uses the AT43DK355 and all its tools and
libraries.
