The M93C66-WMN6TP is a type of integrated circuit (IC) memory framework. It is part of the wide range of serial EEPROM-based ICs from STMicroelectronics, which offer relatively low-cost, flexible memory solutions.

The M93C66-WMN6TP is a type of 2k-byte Serial EEPROM that uses an 8-pin SOITC package, making it suitable for a range of applications in a number of different industries. Specifically, the M93C66-WMN6TP is designed to be used in automotive, computing, consumer, and industrial applications, using various communication standards, such as I²C and SPI, to communicate with the controller.

This EEPROM achieves a high level of compatibility with devices, allowing designers to adopt a wide variety of memory types. Its design addresses operational challenges, with the added advantage of fast programming speeds, as well as improved endurance and reliability in all supported temperatures.

Application Field

The M93C66-WMN6TP is a versatile memory framework that is suitable for a range of applications. It can be used to store data in non-volatile memory, even when the power is switched off. This makes it ideal for automotive, consumer and industrial applications that might encounter sudden power failures, or need to retain data between runs. Additionally, it can be used to store and manage program code, to create a self-programmable micro-controller.

The M93C66-WMN6TP offers a data retention time of up to 20 years, enabling reliable data storage for a variety of purposes. It also has a low operating temperature and an operating temperature-range of -55 to +125 °C, and a high endurance rating, allowing for long-term reliability. As the device offers a wide range of compatibility with controllers and communication systems, it can be used to bridge interactions between different systems. It also offers higher security in the form of write-protection for important data, which can be enabled/disabled by certain commands.

Working Principle

The M93C66-WMN6TP uses several protocols and methods in order to communicate efficiently with its controllers. It supports the I²C protocol, which enables fast communication between the EEPROM and its controllers, usually with a maximum speed of 400 kHz. It also supports the serial peripheral interface (SPI) protocol, which is similar to I²C, but offers more flexibility, usually with speeds of up to 10MHz. Additionally, it also supports High-speed I²C, which is an extension of the I²C protocol, with transfer speeds of up to 3.4 MHz.

Furthermore, the M93C66-WMN6TP also supports write-erase modes, with two main methods: the write-erase All Memory mode and the erase Only mode. The write-erase All Memory mode erases the entire memory before writing data in the new location. This ensures that previously written data is completely wiped before any new data is written. The erase only mode can be used to erase a set range of memory without the need to write any new data. It is important to note that the write-erase All Memory mode is considered more secure, as it ensures that no data is left on the chip after erasure.

The M93C66-WMN6TP also has a memory status/protection register which stores the status/protection of each byte in its memory. This register can be used to set write-protection or write-erase protection for sections of the memory, ensuring that certain data is not modified or erased, even if another write-erase or write operation is attempted.

Overall, the M93C66-WMN6TP enables rapid, yet secure communication between controllers and memory, making it a suitable memory framework for many different applications. Its versatile design allows for a range of compatibility with controllers, and its write-erase modes and register make it a highly secure system for data storage.
