CY7C68034-56BAXC

Overview

The CY7C68034-56BAXC 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 3.3 V with 5 V tolerant inputs, it supports Full Speed (12 Mbps) and High Speed (480 Mbps) signaling. The device features four programmable bulk/interrupt/isochronous endpoints with buffering options, a General Programmable Interface (GPIF), and integrated I2C. Designed for battery-powered applications, it achieves a typical suspend current of 100 µA.

Feature Summary

• Integrates USB 2.0 transceiver, Smart SIE, and enhanced 8051 core in a single chip
• Supports bus- or self-powered operation with ultra-low power consumption
• Includes SmartMedia standard hardware ECC generation for NAND Flash
• Features General Programmable Interface (GPIF) for direct parallel interface connection

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 that the part number suffix matches the required package and temperature specifications. Check for recent Product Discontinuance Notifications (PCN) as this series may have reached end-of-life status. Ensure firmware development tools are compatible with the specific silicon revision before procurement.

Selection Notes

Select the CY7C68034 over the CY7C68033 when designing battery-powered applications due to its lower typical suspend current of 100 µA compared to 300 µA. Choose this controller for designs requiring flexible firmware updates via NAND Flash boot logic rather than fixed-function operations. Consider the 56-pin QFN package constraints and thermal requirements for high-speed data transfer scenarios.

Part Context

This component belongs to the EZ-USB NX2LP-Flex family, which serves as a programmable alternative to the fixed-function EZ-USB NX2LP controllers. It shares architectural similarities with other FX2LP variants but adds specific NAND Flash boot capabilities and flexible endpoint configurations. The family is designed to reduce system cost by integrating glue logic and FIFOs directly onto the silicon die.
