• Manufacturer Part Number: M45PE10-VMN6
• Description: 1 Mbit, Low Voltage, Page-Erasable Serial Flash Memory With Byte-Alterability and a 25 MHz SPI Bus Interface
• Manufacturer: STMICROELECTRONICS [STMicroelectronics]

M45PE10
SUMMARY DESCRIPTION
The M45PE10 is a 1Mbit (128K x 8 bit) Serial
Paged Flash Memory accessed by a high speed
SPI-compatible bus.
The memory 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 fol-
lowed by a Page Program cycle.
The memory is organized as 2 sectors, each con-
taining 256 pages. Each page is 256 bytes wide.
Thus, the whole memory can be viewed as con-
sisting of 512 pages, or 131,072 bytes.
The memory can be erased a page at a time, using
the Page Erase instruction, or a sector at a time,
using the Sector Erase instruction.
In order to meet environmental requirements, ST
offers these devices in ECOPACK® packages.
ECOPACK® packages are Lead-free and RoHS
compliant.
ECOPACK is an ST trademark. ECOPACK speci-
fications are available at: www.st.com.
