STMicroelectronics Expands Family of High-Density Code Storage Serial Flash Memory.Business & Technology Editors
GENEVA--(BUSINESS WIRE)--May 6, 2002
New 4-Mbit and 8-Mbit serial Flash devices offer high-performance and
easy-to-implement code storage for wide range of applications
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 memory technology, today strengthened its position in the code storage market with the introduction of the first 4-Mbit and 8-Mbit devices in its serial Flash family.
The 4-Mbit M25P40 and the 8-Mbit M25P80 are targeted at emerging serial code-download in a wide range of applications, including hard disk drives, DVD players, graphics cards, printers, wireless LANs, ADSL See DSL.
ADSL - Asymmetric Digital Subscriber Line , networking, industrial applications and set-top boxes. Both devices are supplied in the smallest packages available today for these densities.
Serial Flash memories are ideal for applications that require voice and image storage, especially those constrained by power, available pins, space and performance.
The M25P40 and the M25P80 are organized as 8x512-Kbit and 16x512-Kbit sectors, respectively. Data can be read with a clock rate of up to 25MHz. Other features include a sequential read of 168ms for 4-Mbit and 335ms for 8-Mbit, sector or bulk erase, four write protection modes, 1uA deep power-down mode, and hardware/software write protection setting. Both devices operate within a single 2.7-3.6Vcc range. Built using an advanced CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. process, the M25P40 and the M25P80 offer a minimum data retention of 20 years and have a guaranteed write endurance of 100,000 cycles.
Serial Flash memory enables program code to be downloaded upon power-up from external Flash. Typically, parallel Flash packages with more than 28 pins impose a significant overhead. By switching to a 4-pin serial Flash interface, controller or master pin count, board space, power, system noise and overall cost can be greatly reduced.
ST's serial Flash family combines choice and compatibility with rugged and economical code storage. The key feature is the S08 footprint that can accept a density range from 512-Kbits to 8M-bits. A new Micro Leadframe Package Micro Leadframe Package (MLP) is a family of integrated circuit QFN packages, used in surface mounted electronic circuits designs. It is available in 3 versions which are MLPQ (Q stand for Quad), MLPM ( Mstands for Micro) and MLPD (dual). (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. 8), footprint-compatible with the S08 Narrow package, will complete the package range for these products in the second half of 2002. All devices support the 4-pin Serial Peripheral Interface (communications, hardware) Serial Peripheral Interface - (SPI) A serial interface in which a master device supplies clock pulses to exchanges data serially with a slave over two data wires (Master-Slave and Slave-Master). (SPI bus).
The M25P40 comes in an 8-pin S08 package (150-mil), while the M25P80 is offered in the S08 wide package (200-mil). Both devices will be available in volume production in Q2, 2002.
