STMicroelectronics 4Mbit EEPROM memory chip comes out

China, November 22, 2019-STMicroelectronics (ST; New York Stock Exchange code: STM), a leading global semiconductor supplier that spans multiple electronic applications, has launched a new generation of memory chips that integrate unprecedented storage Capacity is combined with read and write speed and reliability. The new product allows us to use the product equipment every day to do more things and enrich our lives and work.

ST's new memory capacity of 4Mbit EEPROM allows small devices to capture more data and store it in the memory via the serial SPI bus. With this memory, smart meters and other instrumentation equipment can increase the amount of data recorded, thereby more effectively managing the energy network, providing a more user-friendly billing method; portable medical equipment can record patient data more intensively and improve medical care Quality; consumer products such as smart wearable devices can support more user functions and higher accuracy; in these applications, the low power consumption of the memory also helps extend battery life. High-capacity memory can also bring benefits to various industrial control and communication infrastructure applications such as network switches.

Benoit Rodrigues, general manager of ST's memory division, said: "ST is the world's largest serial EEPROM chip manufacturer. Serial memory is widely used in consumer, industrial and automotive related equipment systems. We will continue to promote technological innovation. On the market The first 4Mbit EEPROM device is produced using our own CMOS technology, which is currently the most advanced 110nm EEPROM process in the industry. "

ST's M95M04 EEPROM memory has unprecedented storage capacity and excellent energy efficiency, suitable for budget-conscious applications with tight budgets, expanding ST's reputation in the market for its highly reliable and durable 1 billion full memory read and write cycles Memory product family. The new product can write 512 bytes in 5ms, enabling fast system operation with low latency.

Samples are now open for application.

Detailed technical information

M95M04 EEPROM has a high-capacity non-volatile storage function that can be used to store data that needs to be persisted, such as application codes, accuracy calibration tables and user parameters, and intensive data records.

The EEPROM memory with the highest storage capacity on the market is available in small 8-pin SO8N and TSSOP8 packages, which are more cost-effective than competing products, such as EEPROM emulation memory with integrated microcontroller and flash memory, ferroelectric FRAM, and magnetoresistive MRAM. Compared with CMOS EEPROM, these memories have high power consumption and a narrow supply voltage range.

The advantages of M95M04 EEPROM include a wide supply voltage of 1.8V to 5.5V and a data retention period of 40 years. In addition to SO8N and TSSOP8 packages, it also provides the most advanced 8 solder ball WLCSP chip scale package.
