STMicroelectronics' New 256 kbit I2C EEPROM. stmicroelectronics new 256 kbit i2c eeprom. STMicroelectronics is now putting forth a 256 kbit EEPROM memory IC with a three chip select in a TSSOP8 package. STMicroelectronics is now putting forth a 256 kbit EEPROM memory IC with a three chip select in a TSSOP8 package. STM says the non-volatile M24256 is suited for the telecommunications market and that its TSSOP8 package can save space in mobile applications that need high-density EEPROM in the smallest possible package....

STM's ACR Serial Bus EEPROM for PC Motherboards. stms acr serial bus eeprom for pc motherboards. The M34A02 EEPROM is designed for plug and play cards that connect to the PC motherboard SMBus structure. The M34A02 EEPROM contains a two-wire SMBus serial interface that uses a bi-directional data line and one clock line....

STMicroelectronics just announced that all of its Serial EEPROM devices, from 2 to 64-Kbit density and from both the SPI and I2C interface series are now available in the tiny 2 x 3mm MLP8 package, compared to the predecessor 4 x 5mm S08N package, enabling space and cost savings for portable consumer and communications products....

The first of the three is the ST19XR34 with 96K Bytes of user ROM; 34K Bytes of user EEPROM, and 4K Bytes of user RAM. The other two products are the ST19XS08, with 64K Bytes of user ROM and 8K Bytes of user EEPROM, and the ST19XS04, with 48K Bytes of user ROM and 4K Bytes of user EEPROM. Security features and functions common to the three MCUs include security firewalls for memories, a DES accelerator and, in the case of the ST19XR34, a MAP, EEPROM flash programming with 100,000-to-500,000-erase-write-cycle endurance, clock management, and clock frequency and voltage sensors....

If you knew that flash memory is a special type of EEPROM (electrically erasable programmable read-only memory) that can be erased and reprogrammed in blocks instead of one Byte at a time, go to the head of the class.

As a result, most embedded systems that require non-volatile storage of temporary or changing data no longer need separate electrically erasable read only memory (EEPROM) chips. The Flash memory also has virtual EEPROM capability, programming at three to five volts....

Today's 32-bit systems use BIOS for hardware initialization, boot operations, and configuration utilities that reside in the Electrically Erasable Programmable Read Only Memory (EEPROM). Adaptec says that EFI allows these capabilities to reside not only in the EEPROM but in a hard disk, floppy drive, or CD ROM, enabling the EFI driver to be loaded from any of the devices and eliminating the need to flash a new BIOS onto the motherboard....
