概要
Description
- Capacity: 4Gb (512MB) organized in 4096 blocks, each with 64 pages (2KB + 64B spare per page).
- Interface: 8-bit I/O with asynchronous operation, supporting standard NAND flash commands.
- Voltage: Operates at 2.7V–3.6V, suitable for embedded systems.
- Endurance: ~100K program/erase cycles per block.
- Applications: Used in consumer electronics, industrial devices, and legacy storage systems.
The PCB0 suffix indicates the package type (TSOP-48). It requires error correction (ECC) due to bit error rates typical of SLC NAND.
For modern designs, consider newer alternatives (e.g., eMMC/UFS) due to obsolescence risks.
