Overview

Description

M29W400DB55N6E is a 4-Mbit NOR Flash memory device in the M29W family. It provides nonvolatile, byte-addressable storage for firmware and code, suitable as boot or program memory in embedded systems.
Key points:
- Capacity: 4 megabits (0.5 MB)
- Interface: parallel, 8-bit data bus (NOR flash style)
- Operations: random read; erase units (sector/blocks) and chip erase; program/verify via standard flash command set
- Voltage: typically 3.0–3.6 V (exact range depends on variant)
- Speed: indicated by 55 ns access time (verify in datasheet for exact timing)
- Usage: store firmware, boot sources, or code that rarely updates (requires erase before programming)
Note: precise electrical specs, timing, packaging, temperature range, and the meaning of the suffix (DB55N6E) are vendor-specific. Consult the official datasheet for this exact revision to confirm all detailed parameters.

Features

M29W400DB55N6E features (concise):
- 4-Mbit NOR flash memory with dual-bank (DB) architecture
- Read access time: 55 ns
- Single-supply operation: 2.7 V to 3.6 V
- In-system programmable via standard flash command set (read/program, sector/block erase, chip erase)
- Ready/Busy status signaling
- Dual-bank enables simultaneous read in one bank and erase/program in the other
- Endurance: typically 100,000 program/erase cycles per sector
- Data retention: ~20 years
- Temperature range: -40 °C to +85 °C (industrial)
- Package: 8-pin package (e.g., SOIC)

Package

8-pin SOP (SOIC) – a small-outline 8‑pin surface-mount package.

Pinout

- Pin count: 48 pins
- Function: 4-Mbit dual-bank NOR flash memory (non-volatile program memory) with 55 ns access time, typically 2.7–3.6 V operation.

Manufacturer

Manufacturer: Spansion Inc. Spansion was a semiconductor company that designs and manufactures flash memory (NOR/NAND non-volatile memory) for embedded and consumer applications; it has since been acquired and is now part of Cypress Semiconductor (and later Infineon).

Application

- Embedded MCU/SoC code storage and execution (firmware/boot ROM)
- Firmware updates and calibration data in consumer electronics (set-top boxes, printers, routers, digital cameras)
- Automotive and industrial control devices for non-volatile program and data storage
- Replacement for EEPROM in systems requiring higher density, faster reads and sector/block erase capabilities

Equivalent

Equivalent NOR flash (4Mbit, parallel, 5V, ~55ns):
- STMicroelectronics: M29W400CB/DB
- Winbond: W29C040 (and W29C040A)
- SST: SST39SF040
- Macronix: MX29F040B
- Spansion: M29W400DB (same family)
Note: check exact voltage, speed grade, and package for your design.
