EZ-USB FX1™ USB Microcontroller

Full-speed USB Peripheral Controller

—Supports multiple Ready (RDY) inputs and Control

(CTL) outputs

• Integrated, industry standard 8051 with enhanced

features

1.0

Features

• Single-chip integrated USB transceiver, SIE, and

enhanced 8051 microprocessor

• Fit, form and function upgradable to the FX2LP

(CY7C68013A)

—Up to 48-MHz clock rate

—Four clocks per instruction cycle

—Two USARTS

—Three counter/timers

—Expanded interrupt system

—Two data pointers

— Pin-compatible

— Object-code-compatible

— Functionally-compatible (FX1 functionality is a

Subset of the FX2LP)

• Draws no morethan65 mA in any mode making theFX1

suitable for bus powered applications

• 3.3V operation with 5V tolerant inputs

• Smart SIE

• Software: 8051 runs from internal RAM, which is:

— Downloaded via USB

— Loaded from EEPROM

— Externalmemorydevice(128-pinconfigurationonly)

• 16 KBytes of on-chip Code/Data RAM

• 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

• Four programmable BULK/INTERRUPT/ISOCH-

RONOUS endpoints

—Brings glue and FIFOs inside for lower system cost

—Automatic conversion to and from 16-bit buses

—Master or slave operation

— 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

—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

— Allowsdirect connection to most parallel interfaces;

8- and 16-bit

• Three package options—128-pin TQFP, 100-pin TQFP,

and 56-pin QFN Lead-free

— Programmable waveform descriptors and configu-

ration registers to define waveforms
