CY7C64713/14
EZ-USB FX1™ USB Microcontroller
Full-speed USB Peripheral Controller
1.0 Features
• Single-chip integrated USB transceiver, SIE, and
enhanced 8051 microprocessor
• Fit, form and function upgradable to the FX2LP
(CY7C68013A)
— Pin-compatible
— Object-code-compatible
— Functionally-compatible (FX1 functionality is a
Subset of the FX2LP)
• Draws no more than 65 mA in any mode making the FX1
suitable for bus powered applications
• Software: 8051 runs from internal RAM, which is:
— Downloaded via USB
— Loaded from EEPROM
— External memory device (128-pin configuration only)
• 16 KBytes of on-chip Code/Data RAM
• Four programmable BULK/INTERRUPT/ISOCH-
RONOUS endpoints
— Buffering options: double, triple, and quad
• Additional programmable (BULK/INTERRUPT) 64-byte
endpoint
• 8- or 16-bit external data interface
• Smart Media Standard ECC generation
• GPIF
— Allows direct connection to most parallel interfaces;
8- and 16-bit
— Programmable waveform descriptors and configu-
ration registers to define waveforms
— Supports multiple Ready (RDY) inputs and Control
(CTL) outputs
• Integrated, industry standard 8051 with enhanced
features
— Up to 48-MHz clock rate
— Four clocks per instruction cycle
— Two USARTS
— Three counter/timers
— Expanded interrupt system
— Two data pointers
• 3.3V operation with 5V tolerant inputs
• Smart SIE
• Vectored USB interrupts
• Separate data buffers for the Setup and DATA portions
of a CONTROL transfer
• Integrated I²C 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
asynchronous strobes
— Easy interface to ASIC and DSP ICs
• Vectored for FIFO and GPIF interrupts
• Up to 40 general purpose I/Os
• Three package options—128-pin TQFP, 100-pin TQFP,
and 56-pin QFN Lead-free
