STMicroelectronics announces SPI serial flash compatible with the leading chipset family.STMicroelectronics (NYSE NYSE
See: New York Stock Exchange : STM (Scanning Tunneling Microscope) A microscope that can image down to the atomic level. An STM uses a piezoelectric tube with a tiny sharp tip at the end that is moved within nanometers of the object being sampled. ), a leader in Serial Flash, has introduced the new 8-Mbit M25PE80Serial Flash memory for increased network management capabilities. The Serial Flash also provides designers of chipset-based systems that use the Intel 945 Express with a BIOS solution that supports advanced capabilities and increased functionality in laptops, desktop PCs, as well as servers.
ST's new Serial Flash IC supports the Intel 82573E PCI Express* Gigabit Ethernet Controller, featuring Active Management Technology, and the Intel 945Express chipset family with the 82801GB and 82801GR I/O Controller Hub I/O CONTROLLER Hub (ICH) is the name for the microchip Intel 82801, which works as southbridge on motherboards with Intel chipsets (Intel Hub Architecture). It is used to connect and control peripheral devices. .
The M25PE80 offers a thin granularity for erase and program very suitable for BIOS parameters. The memory space is divided into 16 sectors each containing 256 pages; each page is 256 bytes wide. All sectors (64 kbytes) and pages (256 bytes) can be erased independently. The memory offers enhanced protection features to prevent accidental programming or erasure ERASURE, contracts, evidence. The obliteration of a writing; it will render it void or not under the same circumstances as an interlineation. (q.v.) Vide 5 Pet. S. C. R. 560; 11 Co. 88; 4 Cruise, Dig. 368; 13 Vin.

The memory can be write protected by either hardware or software, with a protection granularity of sectors (64 kbytes) for the whole memory area and sub sectors (4 kbytes) inside the sector 0 and the sector 15.
On top of these features, ST's M25PE80 encompasses a standard SPI (1) (Stateful Packet Inspection) See stateful inspection.
(2) (Service Provider Interface) The programming interface for developing Windows drivers under WOSA. bus with an enhanced clock speed of 50 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. for data transfer. This device operates on a 2.7 to 3.6V supply voltage, and features a 1-microamp deep power-down mode to reduce power consumption.
The M25PE80 devices come in the S08 Wide (208 mils) package and in the very thin 5 x 6mm 8-pin MLP (Meridian Lossless Packing) The compression technique used in DVD-Audio that provides the highest audio quality. It delivers two channels at 192 kHz with 24-bit samples or six channels at 96 kHz. (Micro Lead frame Package). The packages use ST's ECOPACK Pub-free technology for RoHS-compliance (the EU's Restriction on Use of Hazardous Substances Directive).
The M25PE80 is specified for the -40 to +85 degrees C operating temperature range. Minimum data retention is 20 years and write endurance is 100,000 cycles.
Samples in 8-Mbit are available now and volume production is ramping-up. Pricing for 100,000 units is $1.35 for the 8-Mbit M25PE80. The 4-Mbit M25PE40is also available and a 16-Mbit is planned.
