M95640-RMN6TP Integrated Circuits (ICs)

Memory

The M95640-RMN6TP is a type of non-volatile memory device that is commonly used in embedded applications and devices. It is a serial EEPROM memory chip, and is specifically designed to store and access parameter data in embedded applications, providing high speed, reliable non-volatile memory access.

The M95640 memory device has a 4-Wire SPI interface and can be operated in either read or write modes, making it suitable for wide range of applications, from consumer products to industrial automation. The device has a wide temperature range and can operate from -40°C to 85°C, making it suitable for use in some challenging environmental conditions.

The M95640-RMN6TP consists of 128kB of data storage in the EEPROM. A data register permits access of either 8-bit or 16-bit bytes, with 32K pages of 512 bytes each, allowing for further re-organization of data. Information stored within the memory device can be read or written with a single command and the device has multiple levels of error checking and correction, ensuring a high level of reliability and data integrity.

Application Fields

The M95640-RMN6TP memory device is most commonly used in embedded processors and systems. It is often used to store and access parameter data, including system settings, program data, and configuration and calibration data for devices. It is also used to store system statistics, as well as audio and video files.

The M95640 is used in a variety of applications, including digital televisions, set-top boxes and audio systems, automotive instrument clusters, gaming consoles, vending machines, and many other types of embedded applications.

Working Principle

The M95640-RMN6TP operates using a 4-wire SPI interface. The interface consists of a Master Clock (MIS). a Master Data (MDI) and two Slave Data (SDI) signals. The three lines are used to transmit data to and from the device using a serial bit-wise protocol.

The M95640-RMN6TP provides programmers with an 8-bit or 16-bit data word for both write and read operations. The device also supports byte and page write operations. A byte write operation requires the programmer to send a byte write command and the specific address of the byte to be written. The programming process consists of toggling the MASTER CLOCK line, writing a byte, and then toggling the appropriate Slave Data line to a High level.

The read operation is initiated by sending the read command, followed by either an 8-bit or a16-bit data word. After receiving the data, the programmer must read the Slave Data lines to ensure data integrity before continuing the programming operation.

The M95640-RMN6TP also supports an Auto-Increment mode. This allows the programmer to write or read multiple bytes without specifying an address each time. The device automatically increments the address after each write or read operation, eliminating the need for programmers to keep track of the address.

The device also features an Error Checking and Correction (ECC) algorithm which ensures the integrity of the written and read data. The device has a 100,000 write endurance and unlimited read endurance, providing reliable access to data in even the most challenging of environments.

Conclusion

The M95640-RMN6TP is a versatile non-volatile memory device that provides data storage solutions for embedded applications. It has a wide temperature range and offers a high level of reliability and data integrity, making it suitable for use in many different applications and environments. Its 4-Wire SPI interface and support for byte and page read and write operations, as well as its error checking and correction algorithm make it an ideal choice for embedded systems.
