W29N04GVSIAA TR

Memory IC Overview

The W29N04GVSIAA TR is a 4 Gbit Single-Level Cell (SLC) NAND flash memory from Winbond, organized as 512M x 8 bits. It operates on a single 2.7V to 3.6V power supply with active current consumption of 25mA at 3V and standby current of 10uA. The device supports a multiplexed 8-bit bus interface for data, addresses, and commands. Key performance metrics include a maximum random read time of 25μs, sequential read cycle of 25ns, page program time of 250μs, and block erase time of 2ms. It offers an endurance of 100,000 erase/program cycles and 10-year data retention. The component is housed in a 48-pin TSOP package and functions within an industrial temperature range of -40°C to 85°C.

Memory IC Procurement Notes

Verify the specific ordering suffix 'TR' indicates tape and reel packaging when sourcing this component. Confirm that the 'S' package code corresponds to the required 48-pin TSOP form factor for your design. Ensure compatibility with the ONFI interface standards if integrating with third-party controllers. Check for any recent Product Change Notifications regarding manufacturing location or material composition updates.

Memory IC Selection Notes

Select this part for designs requiring high endurance and reliable SLC performance in embedded systems with limited pin counts. The 8-bit parallel interface simplifies controller requirements compared to serial alternatives. Consider the 48-pin TSOP footprint constraints during PCB layout. Verify that the system power supply remains stable within the 2.7V to 3.6V operating range to ensure correct device functionality.

Memory IC Part Context

This component belongs to the W29N04GV series of 4 Gbit NAND flash memories. It is designed as a single-chip solution for embedded systems prioritizing low power consumption and compact physical dimensions. The series supports standard NAND interfaces, making it compatible with a wide range of existing memory controllers and host processors used in consumer electronics and industrial equipment.

Memory IC Replacement Considerations

Direct replacements must match the 4 Gbit density, 8-bit width, and 48-pin TSOP package. Verify that alternative parts support the same 2.7V-3.6V voltage range and industrial temperature specifications. Cross-reference command sets and timing parameters to ensure functional compatibility without firmware modifications.

Memory IC FAQ

What is the organization of the memory array?

The memory array is organized into 4,096 erasable blocks, with each block containing 64 programmable pages. Each page consists of 2,048 bytes for main data and 64 bytes for spare data.

How does the Ready/Busy pin function?

The RY/#BY pin is an open-drain output that indicates device status. It outputs low during program, erase, or read operations and returns high when those operations are completed.
