ST intros first 2Mbit serial EEPROM

STMicroelectronics has introduced a 2Mbit serial EEPROM chip.

The M95M02 has an industry-standard SPI high-speed serial interface for fast communication at up to 5MHz at 2.5V.

It can be operated at voltages as low as 1.8V and has a standby mode drawing less than 5µA, for use in battery-operated equipment.

A second new 2Mbit device, the M24M02, communicates via an industry-standard I2C high-speed interface, operating up to 1MHz.

Both devices are available in a SO8N package. 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.

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

The 2-Mbit density M95M02 and M24M02 in the SO8N package are sampling
