CY7C68033/CY7C68034
EZ-USB NX2LP-Flex™ Flexible USB NAND Flash Controller
CY7C68033/CY7C68034 Silicon Features
• Certified compliant for Bus- or Self-powered USB 2.0
operation (TID# 40490118)
• Single-chip, integrated USB 2.0 transceiver and smart SIE
• Ultra low power – 43 mA typical current draw in any mode
• Enhanced 8051 core
— Firmware runs from internal RAM, which is downloaded
from NAND flash at startup
— No external EEPROM required
• 15 KBytes of on-chip Code/Data RAM
— Default NAND firmware ~8 kB
— Default free space ~7 kB
• Four programmable BULK/INTERRUPT/ISOCHRONOUS
endpoints
— Buffering options: double, triple, and quad
• Additional programmable (BULK/INTERRUPT) 64-byte
endpoint
• SmartMedia Standard Hardware ECC generation with 1-bit
correction and 2-bit detection
• GPIF (General Programmable Interface)
— Allows direct connection to most parallel interfaces
— Programmable waveform descriptors and configuration
registers to define waveforms
— Supports multiple Ready (RDY) inputs and Control (CTL)
outputs
• 12 fully-programmable GPIO pins
• Integrated, industry-standard enhanced 8051
— 48-MHz, 24-MHz, or 12-MHz CPU operation
— Four clocks per instruction cycle
— Three counter/timers
— Expanded interrupt system
— Two data pointers
• 3.3V operation with 5V tolerant inputs
• Vectored USB interrupts and GPIF/FIFO interrupts
• Separate data buffers for the Set-up and Data portions of a
CONTROL transfer
• Integrated I2C™ controller, runs at 100 or 400 kHz
• Four integrated FIFOs
— Integrated glue logic and FIFOs lower system cost
— Automatic conversion to and from 16-bit buses
— Master or slave operation
— Uses external clock or asynchronous strobes
— Easy interface to ASIC and DSP ICs
• Available in space saving, 56-pin QFN package
