S34ML02G100BHI003

S34ML02G100BHI003 is a parallel NAND flash memory device from Spansion (now Cypress/WD). It’s part of the S34ML family and provides non-volatile storage for embedded applications.
Key points:
- Capacity and format: approximately 2 Gbit of raw NAND flash, organized in pages/blocks for NAND operation.
- Interface and use: parallel NAND flash with the standard NAND command/address/data protocol; compatible with common ECC schemes and controller interfaces used in embedded systems.
- Electricals and packaging: typically 3.3V operation with an 8‑bit I/O data path; BHI003 is the package code (a surface-mount package suitable for board mounting).
- Purpose: used as a boot/storage medium in devices requiring high-density non-volatile memory.
For exact electrical specs, timing diagrams, endurance, ECC requirements, and packaging details, consult the official datasheet for S34ML02G100BHI003 from Spansion/Cypress (and note any updates from subsequent manufacturer rebranding). If you’re designing a board, verify current availability and package compatibility from the manufacturer or distributors.
