Description
M25P64
The M25P64 is a 64 Mbit (8M x 8) Serial Flash Memory, with advanced write protection
mechanisms, accessed by a high speed SPI-compatible bus.
The memory can be programmed 1 to 256 bytes at a time, using the Page Program
instruction.
An enhanced Fast Program/Erase mode is available to speed up operations in factory
environment. The device enters this mode whenever the V_PPH voltage is applied to the Write
Protect/Enhanced Program Supply Voltage pin (W/V_PP).
The memory is organized as 128 sectors, each containing 256 pages. Each page is 256
bytes wide. Thus, the whole memory can be viewed as consisting of 32768 pages, or
8388608 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 M25P64 in ECOPACK®
packages. ECOPACK® packages are Lead-free and RoHS compliant.
