M29DW641F60ZE6E is a product within the family of NOR Flash memories by Numonyx. It is a parallel Flash memory device with a 8-pin package which provides good balance of performance and cost. This memory has standard features such as byte-programmable parts and high endurance. In its 8-pin micro-package, it has a limited current consumption and its power consumption is minimized due to its low-voltage operation.

M29DW641F60ZE6E is commonly used in applications such as code shadowing, executable-in-place and date storage in industrial, automotive and consumer end equipment.

M29DW641F60ZE6E Application Field:

M29DW641F60ZE6E is suitable for a wide range of embedded applications including:

• Embedded systems with code shadowing and executable-in-place requirements.
• Personal digital assistants and hand-held computers.
• Industrial and automotive control systems.
• Hand-held modems.
• Device programming.
• Data storage.

M29DW641F60ZE6E is also capable of data storage due to its high endurance and low voltage operation, making it suitable for embedded applications in automotive, industrial and consumer applications.

M29DW641F60ZE6E Working Principle:

M29DW641F60ZE6E is a parallel Flash memory device that employs four pins for data exchange (DATA0-DATA3). Addressing is provided on the remaining four pins (ADDR0-ADDR3). Two additional pins are used for chip enabling and write-protect.

The device operates by providing a memory address to a group of addresses within the memory, which is then latched into the internal address register. The data corresponding to the address is then read or written depending on the operation requested.

The device has a sector organization with 16 kB (10-bit) sectors and 4 kB (11-bit) blocks. It also supports a one-time programmable (OTP) sector (lock bit) that can be used to protect the code stored in the 16 kB sector against reprogramming.

The device is also equipped with an in-system programmable (ISP) feature that allow to reprogram or write-protect individual sectors. This feature is a unique and important functionality of the device as it allows for updating of only an application code space, thus reducing time and cost associated with the development and test cycles.

M29DW641F60ZE6E is an efficient, cost-effective and reliable memory solution for a number of embedded applications where code shadowing and executable-in-place capability is required.
