S29JL032J70TFI220

S29JL032J70TFI220 is a 32‑Mbit serial SPI NOR flash memory from Spansion/Cypress. It’s designed for embedded firmware and data storage with a compact package and hardware protection features. Key points:
- Capacity: 32 Mbit (4 MB) of non-volatile flash.
- Interface: SPI serial interface (standard Read/Fast Read); many variants in this family also support Dual/Quad I/O for higher throughput; up to ~70 MHz clock.
- Memory organization: typical 256‑byte pages; sectors (often 4 KB) and larger blocks (64 KB/256 KB) for erase.
- Features: page program, sector/block erase, fast read, deep power-down, and write-protection options.
- Power/temperature: operates from roughly 2.7–3.6 V; industrial temperature variants may be available.
- Package: common 8‑pin SOP/other small packages.
- Applications: firmware boot code, code storage, and data logging in embedded systems.
Note: “TFI220” encodes temperature/packaging options; exact electricals and timings vary by revision—consult the official datasheet for precise specs.
