Lexington, Mass.STMicroelectronics Inc.'s latest flash memory offering is an 8-bit chip with a serial peripheral interface (SPI) aimed at increasing network computing management capabilities and providing designers using Intel 945 Express chipsets with a PC BIOS solution.
The M25PE80 serial flash IC supports the Intel 82573E PCI Express gigabit Ethernet controller with Active Management Technology, and the Intel 945 Express chipset family with the 82801GB and 82801GR I/O controller hub.
The M25PE80 has a thin granularity for erase and program suitable for BIOS parameters. The memory space is divided into 16 sectors each containing 256 pages; each page is 256 bytes wide. All pages and sectors can be erased independently.
The memory offers security features to prevent accidental programming and erasure. The memory can be write-protected by using hardware or software.
The M25PE80 has a standard PCI bus with a clock speed of 50-MHz for data transfer. It operates on a 2.7- to 3.6-V supply voltage, and features a 1-microamp deep power-down mode to reduce power consumption.
The M25PE80 comes in S08-wide and micro lead-frame packages. They use the company's Ecopack Pb-free technology for RoHS compliance.
Samples are available now; volume production is increasing. In 100,000-unit quantities, the 8-bit M25PE80 costs $1.35 each.
