Serial EEPROM portfolio runs from 2 to
128Kbit
Three new devices in the 2 x 3 x 0.6mm MLP8 package now allow designers to choose from footprint-compatible devices at any required density.
STMicroelectronics reckons it is the first company to offer a complete serial EEPROM portfolio from 2 to 128Kbit in both I2C and SPI versions, with all family devices benefiting from space-saving micro leadframe (MLP) package technology Three new devices in the 2 x 3 x 0.6mm MLP8 package now allow designers to choose from footprint-compatible devices at any required density, saving space, cost and development time

Driver drives LED efficiency
STMicroelectronics has introduced a new white LED driver with specific features for small LCD module backlight and high efficiency white LED power supply for portable applications.
Single-chip tuner cuts set-top box parts count
The STB6000 single-chip silicon tuner is designed to replace complex discrete component tuners in set-top boxes used for receiving digital TV or web-based material via satellite.
The M95128 is the first 128Kbit SPI device to reach the market in the MLP8 package size.
As a further benefit, the device has a sub-3uA standby mode, allowing its use in energy-sensitive battery-powered products.
The four- wire SPI interface supports communication at up to 2Mbit/s, and also allows software-based write protection, in addition to standard protection implemented in hardware.
The 64Kbit M24C64 and 128Kbit M24128 complete ST's family of I2C devices in the MLP8 package first announced in March 2007.
The built-in I2C interface supports 400Kbit/s fast mode communication, operating as a slave on the I2C bus.
Both devices reduce current draw to below 1uA in standby mode, to help extend battery life in portable and handheld products.
With their small size, high performance and wide range of capacities, this family of devices is ideal for applications including Bluetooth headsets and modules, wireless LAN adapters, portable media players, cellular handsets and smart phones, camcorders and digital stills cameras.
From a system designer's point of view, the operating voltage range is compatible with virtually all ASICs and chipsets.
The M24C64 and M24128 are even specified to operate with power supplies as low as 1.7V.
Other valuable features include: a write-control input, byte- and page- write modes, random and sequential read modes, self-timed programming cycle and automatic address incrementing.
Device lifetime is greater than one million write cycles, and data retention more than 40 years.
All the devices in the I2C and SPI families, in the MLP-8 package and spanning densities from 2 to 128Kbit, are available now.
The M24C64-FMB6TG is priced at US $0.24 in quantities of 1000 units, the M24128-FMB6TG at US $0.34, and the M95128-RMB6TG at US $0.48 in the same quantities.
