25PE20VP Datasheet – 2Mb Serial Flash Memory

Part number : 25PE20VP, M25PE20-VMN6P

Functions : 2 Mbit, Low Voltage, Page-Erasable Serial Flash Memory

Package information :  SOP 8 Pin, VFQFPN8 Type

Manufacturer : STMicroelectronics, Micron Technology


25PE20VP Flash Memory


The M25PE20 and M25PE10 are 2 Mbit (256K x 8 bit) and 1 Mbit (128K x8 bit) Serial Paged Flash Memories, respectively. They are accessed by a high speed SPI-compatible bus. The memories can be written or programmed 1 to 256 Bytes at a time, using the Page Write or Page Program instruction. The Page Write instruction consists of an integrated Page Erase cycle followed by a Page Program cycle. The M25PE20 memory is organized as 4 sectors, each containing 256 pages. Each page is 256
Bytes wide. Thus, the whole memory can be viewed as consisting of 1024 pages, or 262,144 Bytes.
