2 Mbit EEPROM

20 July 2011 DSP, Micros & Memory

STMicroelectronics has unveiled a 2 Mbit serial EEPROM chip for write-intensive applications.

The M95M02 provides high-density storage in a common package outline and has the same connections and an industry-standard SPI serial interface, allowing use as a direct replacement or upgrade in established system designs. It can be operated at voltages as low as 1,8 V and has a standby mode drawing less than 5 μA, making it suitable for use in low-power or battery-operated equipment. Additionally, the SPI interface enables fast communication at up to 5 MHz at 2,5 V. A second device, the M24M02, communicates via an I²C interface operating up to 1 MHz.

Both devices are available in the SO8N package and offer an additional page, named the Identification Page (256 Bytes), which can be written and, later, permanently locked in read-only mode. This 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.
