ST Microelectronics conquers the need for multiple EEPROMs with its announcement of its new 2-Mbit serial EEPROM memory chips

As a major supplier of EEPROM memories, ST Microelectronics has launched 2-Mbit serial EEPROM memory chips for write-intensive applications which allow designers to replace multiple EEPROMs with a single device and improve parameter management on printed-circuit-boards

These 2-Mbit serial EEPROM memory chips will help save build costs and board size for consumer and industrial applications, such as:

  • TVs
  • Monitors
  • Flat panels
  • Set-top boxes
  • Printers
  • Smart meters
  • Medical equipment
The M95M02 serial EEPROM memory chips provide ultra-high-density storage in the same package outline as lower density alternatives. They also allow use as a direct replacement or upgrade in established system designs as they have the same connections and an industry-standard SPI high-speed serial interface. Operating at voltages as low as 1.8V and a standby mode drawing less than 5uA, make these memory chips 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.

ST’s advanced proprietary EEPROM process technology makes both memory chips available in the cost-effective SO8N package, allowing full footprint compatibility with lower equivalent memory densities. Both devices also offer an additional page, named the Identification Page (256 bytes), 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.
