M29W640GB70ZA6E

Introduction to M29W640GB70ZA6E
- Type: NOR flash memory, part of the M29W family, used for non-volatile code/storage in embedded devices.
- Capacity/organization: 64 Mbit (8 MB) total; typically 8 M x 8 organization.
- Interface: parallel NOR, asynchronous read/write with a command set for programming and erasing.
- Speed/voltage: operates around 2.7–3.6 V; “70” in the name suggests ~70 ns read access time.
- Features: sector/block erase, typical protection options, and low-power modes.
- Applications: firmware/boot code storage for microcontrollers and embedded processors.
- Packaging/availability: offered in common NOR flash packages (e.g., surface-mount 48-pin variants) and multiple densities/grades.
- Note: For exact electrical specs, timing charts, endurance/retention, and command set details, consult the vendor datasheet.
