The M27W201-80N6 is classifiable as a memory, typically used for storing binary static data. Developed by STMicroelectronics, the device is, among other specifications, characterized by a 1.8V voltage, a 6 ns maximum access time, 16 Mbit memory size, and 120-pin TQFP package. It is a common choice for applications requiring excellent performance, low power consumption, and small size.

The M27W201 is constructed with a non-volatile memory core and an integrated controller, allowing it to be programmed and safely erased once. Its 2,097,152-bit array is divided into 128 sectors and can hold up to 125 individual data blocks. This uniform structure makes the device attractive to many applications since the same programming algorithm can be used multiple times.

Mainly used as low-cost flash replacement in automotive applications and 2D/3D graphic cards, the M27W201 is highly reliable due to its signature promise of "no double or multi-bit failures". It is also used in automotive instrument clusters and body electronics because of its fast read speed, making it ideal for applications with very sensitive memory requirements. Additionally, the device can be used in automotive engine control systems and gear box control for fault code logging.

The M27W201 is designed with a variety of features to increase flexibility and overall system performance. This includes a configurable standby mode for power-saving, an industry-standard high speed SPI interface for communication and programming, a pin-configurable protection circuit for full adjudication, and a boot sector for improved memory protection.

The M27W201 works with a unique algorithm based on response time and accessibility. When triggered, it runs the initiation sequence, wherein the device will search for a low VDD signal and, in response, start the switch off process and cleanup sequence. The operating frequency of the device will start to decrease to the minimum, power-saving VDD level, while the protection circuit is activated to ensure the storage integrity of the stored codes in the other parts of the device. Once all that is complete, the programmed data is stored safely. Subsequently, whenever the device needs to be reset, the same process begins by searching for the same low VDD signal. The device will then return to the operational level and the program stored in memory will be resumed.

In addition to its features and functions, the M27W201 is characterized by a wide temperature range of -40°C to 85°C and is compliant to the Pb-free assembly process. It also meets the AEC-Q100 standard, making it suitable for automotive electronics applications.

The M27W201 is an efficient, reliable and low-cost memory device that is highly suitable for automotive and embedded applications. Its features and functions make it a great choice for a wide range of applications - especially those demanding fast read and write speeds, low power consumptions, and long-term reliability.
