M29W320DT70N6E

M29W320DT70N6E is a 32‑Mbit (4‑Mbyte) NAND flash memory device from the M29W family (Macronix/ST‑style naming). It provides non-volatile storage for firmware and data in embedded systems. The suffixes indicate grade details: “DT”/“N6E” reflect package, voltage, and temperature options, while “70” typically points to an approximate access time of 70 ns. It is designed for standard NAND flash operations—read, program (page write), and erase (block erase)—and is organized into pages and blocks (exact sizes depend on the device variant). Typical operation uses a single supply around 3.3 V (with an operating range that can cover related voltages, per the grade). It is suitable for applications requiring persistent storage in environments defined by its voltage and temperature specifications.
For precise specs (capacity, page/block sizes, timing, voltage range, temperature range, and packaging), consult the official M29W320DT70N6E datasheet from Macronix or the supplier’s catalog.

Manufacturer: Spansion.
Spansion is a semiconductor company that designs and produces non-volatile flash memory (NOR/NAND) for embedded systems. It originated as a joint venture between AMD and Fujitsu and was later acquired by Cypress Semiconductor.

Typical application areas for M29W320DT70N6E (32‑Mbit NOR flash) include:
- Boot code and firmware storage for embedded microcontrollers/MPUs
- In-system programming and firmware updates in automotive ECUs (and infotainment)
- Non-volatile storage for consumer electronics (set-top boxes, digital cameras, printers)
- Firmware/data storage in networking/telecom gear (routers, modems, switches)
- Industrial automation and control systems (PLCs, motor controllers)
- Any embedded system requiring fast random reads, sector erase and reliable long‑life memory
Note: Use cases center on nonvolatile code/data storage with fast access and resequenced erases.

It is in an 8-pin SOP (SOIC-8) package.
