EEPROM Devices suit I2C and SPI bus applications.
Press Release Summary:
Housed in 4.5 x 3.1 mm TSSOP8 package, Models M95512 and M24512 are 512-kbit devices that use 1.65 V, 0.18 micron EEPROM process technology. Compatible with SPI bus serial interface, Model M95512 offers high-speed frequency of 10 MHz and above with 5 ms write time. Model M24512 features I2C serial interface with 400 kHz clock rate. Both operate in 1.8-5.5 V and 2.5-5.5 V ranges. Units are suited for applications that have large amounts of rapidly changing parameter data.
Original Press Release:
STMicroelectronics Squeezes Enhanced 512-kbit I2C and SPI Low-Voltage Serial EEPROMs into Very Small Packages
1.8V operation and small package benefit all parameter storage applications
Geneva, March 9, 2005 - STMicroelectronics (NYSE: STM), a world leader in serial non-volatile memory ICs, today introduced two 1.8V-operation 512-kbit EEPROM devices in a TSSOP8 package for I2C (Intelligent Interface Controller) and SPI (Serial Peripheral Interface) bus applications.
The M95512 and M24512 are the latest devices to use ST's advanced 1.65V, 0.18-micron EEPROM process technology, which makes the company the first to fit a large EEPROM density of 512 kbits into a small and thin package (4.5 x 3.1mm). The introduction of the TSSOP8 package, combined with 1.8V operation, enables many manufacturers to reduce board space as well as offer slimmer and lighter end-products.
These new EEPROMs will be used in applications that have a large amount of rapidly changing parameter data, such as video-game systems and electronic toys, digital cameras, car radios, navigation, pagers, set-top boxes, digital cameras, PDAs, MP3 players/recorders and other portable consumer applications. PC servers, printers and portable scanners will also benefit, as well as medical equipment and communications systems.
The new M95512, which is compatible with the SPI bus serial interface, offers high speed frequency (10MHz and above) with a 5ms Write time. The M24512 features an I2C serial interface with a 400kHz clock rate. Both devices operate in two voltage ranges: 1.8V to 5.5V; and 2.5V to 5.5V.
In addition to the TSSOP8, the M95512 and M24512 also come in the S08 Narrow (150mm) package, and use ST's ECOPACK Pb-free technology for RoHS-compliance (the EU's Restriction on Use of Hazardous Substances Directive). These memories are specified for the -40 to +85 degrees C operating temperature range. Minimum data retention is 40 years and write endurance is 100,000 cycles.
The M95512 in TSSOP8 is already sampling and available in volume; the M24512 is planned to sample and to be in production by Q2 2005. Prices start at $1.60 for the M95512 and $1.45 for the M24512, both in quantities of 10,000.
ST's serial EEPROM family roadmap for 2005 also includes a 1-Mbit density in an SO8 package and a 256-kbit device in TSSOP8 and S08 packages.
