Functional Overview
USB Signaling Speed
FX2 operates at two of the three rates defined in the Universal Serial Bus Specification Revision 2.0, dated April 27, 2000:
• Full speed, with a signaling bit rate of 12 Mbps
• High speed, with a signaling bit rate of 480 Mbps
FX2 does not support the low-speed signaling mode of 1.5 Mbps.
3.2
8051 Microprocessor
The 8051 microprocessor embedded in the FX2 family has 256 bytes of register RAM, an expanded interrupt system, three
timer/counters, and two USARTs.
