W29N04KZBIBG

Memory IC Overview

The W29N04KZBIBG is a 4G-bit Single-Level Cell NAND flash memory manufactured by Winbond Electronics. It operates on a single 1.7V to 1.95V power supply and features an x8 data bus width. The device is housed in a 63-ball VFBGA package with SMD/SMT installation style. It supports industrial temperature ranges from -40°C to +85°C and includes hardware write protect capabilities via the #WP pin.

Memory IC Feature Summary

• Supports standard NAND flash interface with multiplexed 8-bit bus for data, address, and command transfer.
• Utilizes Single-Level Cell (SLC) technology for high endurance and long data retention.
• Includes dedicated Ready/Busy status monitoring and hardware write protection functions.

Memory IC Applications

• Code shadowing to RAM
• Solid state storage applications
• Embedded systems with limited space and pins

Memory IC Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific ordering suffix matches the required voltage, package, and temperature grade specifications. Ensure compliance with RoHS directives and check for any active product lifecycle notices before finalizing procurement plans.

Memory IC Selection Notes

Select this component for designs requiring low power consumption and high density in a compact footprint. The x8 interface configuration suits systems needing simpler bus architectures compared to x16 variants. Ensure the host controller supports the standard NAND command set and provides adequate power regulation within the 1.7V to 1.95V operating range.

Memory IC Part Context

This part belongs to the W29N04KW/ZxxBG family of 4G-bit NAND flash memories. It shares architectural similarities with other variants in the series but differs in specific electrical characteristics and packaging options. The ZxxBG designation indicates the specific combination of voltage, package type, and temperature rating defined by the manufacturer.

Memory IC Replacement Considerations

Direct substitutes include other W29N04KW/ZxxBG variants with compatible package codes and voltage levels. Verify pin compatibility and command set adherence when considering alternative manufacturers. Cross-reference datasheets to ensure equivalent endurance and retention specifications are met.
