Its program memory is a 24-Kbyte mask programmable 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 www.

com 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 minimum 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...
