1Mbit Serial EEPROM in SO8 Narrow Package from STMicroelectronics

STMicroelectronics has announced a new 1-Mbit serial EEPROM – the M24M01 – which is available in the tiny SO8N package with 150-mil (3.8mm) body width. This serial EEPROM is said to be the only device in the market to squeeze this high memory density into such a small package. Also offered in SO8W, the chip, with its I2C two-wire serial interface, is intended for applications such as consumer electronics products and medical equipment which needs to store large amounts of frequently changing parameter data. ST’s I2C EEPROM family now offers 1-Kbit to 1-Mbit devices -the broadest portfolio on the market.
The M24M01 supports 100 kHz and 400 kHz clock frequencies, in full compliance with the I2C specification, and operates over a wide 1.8V to 5.5V supply-voltage range. Organized as 128-Kbits x 8, it supports Byte and Page Write modes, with a fast Write time of 256 Bytes in less than 5ms. Improved input noise filtering protects against spurious Write operations in electrically noisy environments. Data retention is more than 40 years, with Write Endurance of more than 1 million Write cycles. The operating temperature range is -40 to +85 degrees C.

The compact device uses ST’s advanced 0.18-micron EEPROM process technology to achieve its high density. The very small size of the SO8N package will offer new opportunities for manufacturers of digital TV sets, DVD players, set-top boxes and medical technology to reduce the board space required in their applications, while increasing the memory available for setup parameters, tuning information, user preferences and other data.

The M24M01 is available now in sample quantities, in both SO8N and SO8W RoHS-compliant packages, with volume production planned for February 2007. ST is also planning to shortly introduce a ‘sister’ product: a 1-Mbit EEPROM with an SPI bus. Pricing for the M24M01 in volume is $1.40.
