Serial Flash Memories offer data and parameter storage.
Press Release Summary:
Offered in 1-, 2-, and 4-Mbit densities, Series M25PE is accessed through SPI bus, with clock speed of 25 MHz for data transfer. Operating on 2.7-3.6 V, units offer 256 Byte Page Write, 64 kbytes Erase by Block, dedicated device signature, bulk erase instruction, and specific write protection. Memories maintain continuity with serial EPROMs in pin-out and are suited for optical mice and PC motherboards, as well as Ethernet, Wi-Fi, and Bluetooth connectivity applications.
Original Press Release:
ST Extends its Serial Flash Offering With New SPI-Standard Pin-out Devices in 1-, 2-, and 4-Mbit Densities
Geneva, July 13, 2005 - STMicroelectronics (NYSE: STM), the worldwide leader in Serial Flash*, has introduced a new family of high-speed low-voltage SPI-standard pin-out Serial Flash memories for both data and parameter storage. A major advantage of the new M25PE family is to maintain continuity with serial EEPROMs in pin-out, allowing flexible upgradeability, which means easy implementation and saving time on designs.
These new memories are suited to various applications including those in: various consumer markets; in computing applications, such as optical mice and PC motherboards; in connectivity applications such as Ethernet, Wi-Fi, and Bluetooth; and in many others that require fast changing data and compatibility with the industry-standard SPI (Serial Peripheral Interface) EEPROM pin-out.
The M25PE family offers high flexibility; fine granularity of 256-byte Page Write, allowing fast-changing data to be stored with minimum system overhead; Fast Read throughput; Erase by Block (64 kbytes); and a flexible command architecture enabling next-generation feature-rich electronic equipment at optimal cost. In addition, a hardware protection of the top sector (64 kbytes) is offered and other features such as Dedicated Device Signature, Bulk Erase Instruction, and Specific Write Protection.
The M25PE devices are accessed through a standard SPI bus with an enhanced clock speed of 25MHz for data transfer. The M25PE series operate on a 2.7 to 3.6V supply voltage, and to reduce power consumption, they feature a 1-microamp deep power-down mode.
The M25PE 1- and 2-Mbit devices fit in the S08 Narrow (150mils); the M25PE 4-Mbit comes in the S08 Wide (208mils) package. In addition, all M25PE densities are also available in the very thin 5x6mm 8-pin MLP (Micro Leadframe Package). The packages use ST's ECOPACK Pb-free technology for RoHS-compliance (the EU's Restriction on Use of Hazardous Substances Directive).
The M25PE family 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 1-, 2-, and 4-Mbit are available now and volume production is ramping up. An 8-Mbit device offering a higher clock frequency of 50MHz is planned for the end of 2005. Pricing for 10,000 units is $0.70 for the 1-Mbit M25PE10; $0.85 for the 2-Mbit M25PE20; and finally $1 for the 4-Mbit M25PE40.
