CY7C68033-56BAXC

Overview

The CY7C68033-56BAXC 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, Smart SIE, and an enhanced 8051 microcontroller with 15 KBytes of on-chip RAM. Operating at High Speed (480 Mbps) or Full Speed (12 Mbps), it supports bus- or self-powered designs with typical current draw of 43 mA. The device features four programmable endpoints, a General Programmable Interface (GPIF), and integrated I2C controller. It operates on a 3.3 V supply with 5 V tolerant inputs and is housed in a 56-pin QFN package.

Feature Summary

• Integrates USB 2.0 transceiver, Smart SIE, and enhanced 8051 core for cost-effective NAND Flash mass storage solutions
• Supports firmware execution from internal RAM downloaded from NAND Flash, eliminating external EEPROM requirements
• Features General Programmable Interface (GPIF) for direct connection to parallel interfaces and DSP processors
• Includes hardware ECC generation with 1-bit correction and 2-bit detection compliant with SmartMedia standards

Applications

• NAND Flash-based GPS devices
• NAND Flash-based DVB video capture devices
• Wireless pointer/presenter tools with NAND Flash storage
• NAND Flash-based MP3 players
• Biometric security devices with NAND Flash storage

Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm RoHS compliance status and check for End-of-Life (EOL) notifications prior to procurement. Ensure design compatibility with the 56-pin QFN package dimensions and thermal requirements. Validate that the specific suffix matches the required electrical characteristics and packaging specifications.

Selection Notes

Select this component for applications requiring flexible firmware customization for USB mass storage. It is suitable for designs needing low power consumption and high data throughput via High-Speed USB. Consider the 15 KBytes RAM limit for complex firmware implementations. Evaluate the GPIF capabilities if interfacing with non-standard parallel peripherals or ASICs is required.

Part Context

The CY7C68033 belongs to the EZ-USB NX2LP-Flex family, which provides a programmable alternative to fixed-function controllers like the CY7C68024. It shares architectural similarities with the FX2LP but includes dedicated NAND boot logic and ECC hardware. This family enables rapid development of USB storage devices by allowing firmware updates without changing silicon.

Replacement Considerations

CY7C68034-56BAXC: Offers identical functionality with lower suspend current for battery-powered applications.
