Serial Flash families High performance memories for code, data and parameter storage The leader in Serial Flash memories, STMicrolectronics is delivering in volume the M25P, M25PE and M45PE families, specifically designed to meet all non-volatile storage requirements, but at a highly competitive price. The use of a Serial-access Flash memory for code, data or parameter storage enables a significant cost reduction at board and overall application levels, while maintaining high performance. ST Serial Flash families for code, data and parameter storage are the optimum solution in terms of flexibility, small package size, high frequencies and cost-effectiveness. M25P family, tailored for code storage The Serial Flash M25P portfolio ranges from 512Kb to 128Mb and is tailored for code storage and other non-volatile memory applications. The M25P solution creates added-value for all applications requiring fast downloads and code execution, such as hard disk drives, multi-function printers, graphic cards, optical disk drives, DVD players, digital TV and cameras. New and diverse applications such as wireless LANs, Set-Top Boxes, DSL and cable modems are turning to Serial Flash to reduce controller or ASIC pin counts, board space, power consumption, software development and overall system costs. www.st.com M25PE/M45PE families, perfect for data and parameter storage From 1 to 16Mb, the M25PE/M45PE series creates added-value for all applications requiring fast updates of data and parameters (starting from a single byte) in non-volatile memories, such as digital answering machines (DECT, corded phones), pagers, digital cameras, home video game systems, wireless LANs, fax machines, cellular phones, voice memo recorders, PDAs, MP3 players/ recorders, monitors, flat display panels, GPS systems and general data loggers. M25P family, tailored for code storage The high speed, low-voltage M25P family reads and programs data through a SPI interface at a frequency of 50MHz and above. With dedicated software and hardware features to protect memory content, the M25P is supplied with a single voltage of 2.7 to 3.6V and, in order to reduce power consumption, features a deep power-down mode that draws less than 1A. Moreover, a four-wire SPI interface considerably reduces the bus master pin count, resulting in increased integration and cost-competitiveness. M25P Serial Flash memories are available in MLP, SO and TSSOP8 (for 512Kb) packages.

They offer the best compromise between die size and granularity, as the erase operation inherent to the Flash technology can be performed down to the small size of one page of 256 Bytes. In addition, the internal logic is flexible enough to enable EEPROM-style byte alterability when updating (erase + program), from one byte up to a full page of 256 Bytes in a single shot. The devices' high speed (33 to 50MHz and above) enables fast read instructions; significantly reducing access time for large amounts of data through the serial bus. The power supply for the M25PE/M45PE is the extended 3V range (2.7 to 3.6V) and, in order to reduce power consumption, the M25PE/M45PE series feature a deep power-down mode that draws less than 1A. The M25PE family offers a standard serial SPI pin-out, while the M45PE has a specific SPI pin-out. Both families are available in S08 and MLP packages. This flexibility makes the M25PE and M45PE Flash series as user-friendly as EEPROM technology.
