If the USB data rate is 480MHz , how on hell will a 50MHz 80c51 process data at this bandwidth? But, look at it the other way around. A 50MHz mcu could easily choke the 12Mbit/s that full speed has to offer. Unfortunately the USB engine in the Silabs C8051F34x can not even sustain 12Mbit/s as Tsuneo already found out quite some time ago. And personally I've always wondered why they didn't add USB to the C8051F06x which can generate 4MByte of adc data per second (2x 16bit @ 1MS/s). Maarten |

| it is a common misconception... | 01/01/70 00:00 | |

| Maybe, maybe not. | 01/01/70 00:00 | |
| Yes, things gets complicated at higher speeds | 01/01/70 00:00 | |
| you are fortunate | 01/01/70 00:00 | |
| Not lucky. Errata came much too late | 01/01/70 00:00 | |
| What do you expect to do with data? | 01/01/70 00:00 | |
