STMicroelectronics Develops 2Mb Serial EEPROM

STMicroelectronics has launched M95M02, a 2Mb serial EEPROM chip for write-intensive applications. The IC allows designers to replace multiple EEPROMs with a single device and improve parameter management on printed circuit boards (PCBs). This breakthrough will help save build costs and board size for consumer and industrial applications, such as TVs and monitors, flat panels, set-top boxes, printers, smart meters, and also equipment used in medical applications.

The M95M02 provides ultra-high-density storage in the same package outline as lower density alternatives. It also has the same connections and an industry-standard SPI high-speed serial interface, allowing use as a direct replacement or upgrade in established system designs. It can be operated at voltages as low as 1.8V and has a standby mode drawing less than 5µA, making it ideal for use in low-power or battery-operated equipment. Additionally, the SPI interface enables fast communication at up to 5MHz at 2.5V. A second new 2-Mbit device, the M24M02, communicates via an industry-standard I2C high-speed interface, operating up to 1MHz.

Both devices are manufactured on ST’s advanced proprietary EEPROM process technology and are available in the SO8N package, allowing full footprint compatibility with lower equivalent memory densities. Both devices also offer an additional page, named the Identification Page (256B), which can be written and, later, permanently locked in read-only mode. This Identification Page offers flexibility in the application board production line, as it can be used to store unique identification parameters, and/or parameters specific to the production process.

These two new serial ICs join ST’s established EEPROM portfolio, which includes the M95 series (SPI) and M24 series (I2C) offering densities from 1kb to 1Mb.
