Description
The M25P40 is a 4 Mbit (512 K × 8) Serial Flash memory, with advanced write protection
mechanisms, accessed by a high speed SPI-compatible bus. The M25P40 features high
performance instructions allowing clock frequency up to 75 MHz.
The memory can be programmed 1 to 256 bytes at a time, using the Page Program
instruction.
The memory is organized as 8 sectors, each containing 256 pages. Each page is 256 bytes
wide. Thus, the whole memory can be viewed as consisting of 2048 pages, or 524,288
bytes.
The whole memory can be erased using the Bulk Erase instruction, or a sector at a time,
using the Sector Erase instruction.
In order to meet environmental requirements, Numonyx offers the M25P40 in RoHS
compliant packages, which are Lead-free. RoHS specifications are available at:
www.Numonyx.com.
This datasheet details the functionality of the M25P40 devices, based on the previous 150
nm process or based on the current 110 nm process (available since August 2008). The
new device in the 110 nm process has the following additional features and is completely
backward compatible with the old one in 150 nm:

identified by process identification digit "4" in the device marking and process letter "B" in the part number.
improved max frequency (Fast Read) to 75 MHz in the standard Vcc range 2.7 V to
3.6 V, while the max frequency (Fast Read) in the extended Vcc range 2.3 V to 2.7 V is
40 MHz
