Cypress High-Speed USB Peripheral Selection
Guide
The CY7C68013 is Cypress Semiconductor's first generation
high-speed USB peripheral device and is an integrated
USB 2.0 solution that fully utilizes the bandwidth capabilities
of USB 2.0. The FX2™ family offers higher performance and
a higher level of integration than the previous EZ-USB prod-
ucts, including a 40x jump to a 480 Mbits/sec signaling rate.
The FX2 builds on the EZ-USB FX device by providing USB
2.0 support with an integrated transceiver, smart SIE, en-
hanced 8051 microcontroller, and a memory and programma-
ble I/O interface. The CY7C68001 is Cypress Semiconduc-
tor's USB Serial Interface Engine for High Speed USB 2.0
peripheral designs. EZ-USB SX2™ is a high-performance,
yet extremely cost-effective solution that integrates a USB 2.0
transceiver, a “smart” SIE, a high-speed PLL, four highly con-
figurable endpoints sharing a 4KB FIFO space, and a very
simple local bus interface. EZ-USB FX2 and SX2 can both
operate at both high speed or full speed.
