CY7C68013A-56LTXC

USB Signaling Speed FX2LP operates at two of the three rates defined in the USB 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 FX2LP does not support the Low Speed signaling mode of 1.5 Mbps. 8051 Microprocessor The 8051 microprocessor embedded in the FX2LP family has 256 bytes of register RAM, an expanded interrupt system, three timer/counters, and two USARTs. 8051 Clock Frequency FX2LP has an on-chip oscillator circuit that uses an external 24-MHz (±100 ppm) crystal with the following characteristics: ■ Parallel resonant ■ Fundamental mode ■ 500-W drive level ■ 12-pF (5% tolerance) load capacitors An on-chip PLL multiplies the 24-MHz oscillator up to 480 MHz, as required by the transceiver/PHY; internal counters divide it down for use as the 8051 clock. The default 8051 clock frequency is 12 MHz. The clock frequency of the 8051 can be changed by the 8051 through the CPUCS register, dynamically.
