Übersicht
Description
- Density and voltage: 128 Mbit (16 MB) with 3.3 V operation (P33).
- Interface and addressing: parallel NOR flash with an 8-bit data bus (x8) and 24-bit addressing (typical for NOR devices).
- Speed and access: read access around 70 ns (T70A) with random and sequential reads.
- Organization and operations: standard NOR-flash features—pages (often a few hundred bytes), 64 KB blocks (and sometimes larger erase regions), page program, block/chip erase, and WRITE ENABLE/DISABLE controls.
- Reliability features: status register, write/erase protection options, and typical endurance in the range of 10^4–10^5 erase cycles per block; long data retention.
- Package: commonly in standard NOR flash packages (e.g., 48-pin SOP/TSOP or similar).
Use cases: firmware/BIOS-like storage, boot code, or nonvolatile data in embedded systems.
For exact pinout, timings, block layout, and electrical specs, consult the official datasheet for JS28F128P33TF70A from the vendor.
