Description

M29W640GB70ZA6E is a Macronix (MXIC) 64‑Mbit NOR flash memory device. It provides non‑volatile storage with a parallel (8‑bit) data bus, typically organized as 8 MB of memory. Key specs often include 3.0–3.6 V operation, ~70 ns access time, and standard NOR flash command set (Read, Byte/Word program, Block erase, and protect/suspend features). Because it is NOR flash, it offers fast random‑address reads and predictable code storage behavior, making it suitable for firmware, boot code, and other executable data in embedded systems. It does not employ wear leveling like NAND memory and is typically packaged in a multi‑pin leaded package (with ZA6E indicating a specific package/date code). In short, it’s a high‑reliability, code‑storage memory used to keep firmware persistent in microcontroller or processor‑based designs. For exact electrical characteristics, timing, package, and protection features, refer to the official datasheet.

Features

Here are the typical features of M29W640GB70ZA6E (64-Mbit NOR Flash):
- Capacity: 64 Mbit NOR Flash (8 MB)
- Speed: 70 ns read access time
- Voltage: 2.7–3.6 V operation (I/O suffix matches supply)
- Architecture: Uniform erase blocks (sector/block erase)
- Programming: Byte/word programming and page programming (typical page size ~256 bytes)
- Protection: Block/security protection features and hardware write protection
- Endurance/Retention: Endurance up to about 100k erase/program cycles; data retention > ~20 years
- Power modes: Deep power-down and low-power standby options
- Reliability: Read/verify options and status registers for operation checking
Note: exact block sizes, page size, and voltage ranges can vary by package and revision; refer to the specific datasheet for final numbers.
