First 1-Mbit Serial EEPROM with SPI interface in SO8 narrow package
(Technology News, 31 Jul 2007 )
STMicroelectronics, a world leader in serial non-volatile memory ICs, has announced a new 1-Mbit serial EEPROM with SPI bus (serial peripheral interface) in the tiny SO8N package with 150-mil (3.8mm) body width – the first SPI serial EEPROM in the market to squeeze this high memory density into such a small package. Also offered in the wider SO8W, the new M95M01 is intended for the storage of fast-changing parameter data in consumer electronics products such as digital TVs (DTV) DVD players and gaming, as well as in medical equipment, industrial, car infotainment and computer peripherals. ST’s SPI EEPROM family now offers 1-Kbit to 1-Mbit devices – the broadest portfolio on the market.
The M95M01 is organized as 128-Kbits x 8, and supports Byte and Page Write modes with a fast Write time of 256 Bytes in less than 5ms (less than 13-microseconds/byte typical). The chips are specified to retain Data for more than 40 years, and offer Write endurance of more than 1 million Write cycles. The operating temperature range for these serial EEPROMs is -40 to +85 degrees C, and the memory operates over a wide 1.8V to 5.5V supply-voltage range for maximum flexibility.
The very small size of the SO8N package, coupled with its fast SPI interface, will offer new opportunities for manufacturers of digital TV sets, DVD players and medical technology to reduce the board space required in their applications, while increasing the amount of fast access memory available for setup parameters, tuning information, user preferences and other data.
