CY7C68013
EZ-USB FX2™ USB Microcontroller
1.0 EZ-USB FX2 Features
• Supports bus-powered applications by using renumer-
ation
• Single-chip integrated USB 2.0 Transceiver, SIE, and
Enhanced 8051 Microprocessor
• Software: 8051 code runs from:
— Internal RAM, which is downloaded via USB
— Internal RAM, which is loaded from EEPROM
— External memory device (128 pin package
• Four programmable BULK/INTERRUPT/
ISOCHRONOUS endpoints
— Buffering options: double, triple and quad
• 8- or 16-bit external data interface
• GPIF
— Allows direct connection to most parallel interface
— Programmable waveform descriptors and configu-
ration registers to define waveforms
— Supports multiple Ready (RDY) inputs and Control
(CTL) outputs
• Integrated, industry standard enhanced 8051:
• 3.3V operation
• Smart Serial Interface Engine
• Vectored USB interrupts
• Separate data buffers for the SETUP and DATA portions
of a CONTROL transfer
• Integrated I²C-compatible controller, runs at 100 or 400
kHz
• 48-MHz, 24-MHz, or 12-MHz 8051 operation
• Four integrated FIFOs
— Brings glue and FIFOs inside for lower system cost
— Automatic conversion to and from 16-bit buses
— Master or slave operation
— FIFOs can use externally supplied clock or asyn-
chronous strobes
— Easy interface to ASIC and DSP ICs
• Special autovectors for FIFO and GPIF interrupts
• Up to 40 general-purpose I/Os
— Up to 48-MHz clock rate
— Four clocks per instruction cycle
— Two USARTS
— Three counter/timers
• Four package options—128-pin TQFP, 100-pin TQFP,
56-pin QFN and 56-pin SSOP
• Four packages are defined for the family: 56 SSOP, 56
QFN, 100 TQFP, and 128 TQFP
— Expanded interrupt system
— Two data pointers
