CY7C68033-56LFXC

Overview

The CY7C68033-56LFXC is a firmware-based, programmable USB 2.0 NAND Flash controller from the EZ-USB NX2LP-Flex family. It integrates a USB 2.0 transceiver, serial interface engine (SIE), enhanced 8051 microcontroller, and programmable peripheral interface (GPIF) in a single chip. Operating at 3.3 V with 5 V tolerant inputs, it supports Full-Speed (12 Mbps) and High-Speed (480 Mbps) modes. The device features 15 KBytes of on-chip code/data RAM, four programmable endpoints with buffering options, and hardware ECC generation. It utilizes an internal 24 MHz crystal oscillator and includes an integrated I2C controller.

Feature Summary

• Integrates USB 2.0 transceiver, SIE, enhanced 8051 core, and GPIF for flexible NAND Flash control
• Supports firmware execution from internal RAM downloaded from NAND Flash at startup without external EEPROM
• Provides SmartMedia standard hardware ECC generation with 1-bit correction and 2-bit detection
• Features General Programmable Interface (GPIF) for direct connection to parallel interfaces and multiple ready/control signals

Applications

• NAND Flash-based GPS devices
• NAND Flash-based DVB video capture devices
• Wireless pointer/presenter tools with NAND Flash storage
• NAND Flash-based MPEG/TV conversion devices
• Legacy conversion devices with NAND Flash storage

Procurement Notes

Verify component authenticity through authorized distributors or Cypress Semiconductor Corporation channels. Confirm RoHS compliance status as specified in official documentation. Check for obsolescence notices or lifecycle status updates prior to procurement. Ensure packaging specifications match design requirements. Validate part number suffixes against manufacturer ordering guides.

Selection Notes

Select CY7C68033-56LFXC for non-battery powered applications requiring lower suspend current tolerance compared to the CY7C68034 variant. Choose this controller when firmware flexibility is needed for custom NAND Flash management algorithms. Consider the 56-pin QFN package constraints for PCB layout. Evaluate the 15 KBytes RAM availability for complex firmware implementations versus default firmware usage.

Part Context

The CY7C68033-56LFXC belongs to the EZ-USB NX2LP-Flex series, which serves as a programmable alternative to fixed-function controllers like the CY7C68023/CY7C68024. This family enables cost-effective, feature-rich NAND Flash applications by combining USB connectivity with embedded processing capabilities in a compact form factor suitable for mass storage and multimedia devices.

Replacement Considerations

CY7C68034-56LFXC is the battery-powered counterpart within the same family.
