M45PE16数据手册集成电路（IC）的存储器规格书PDF

描述 Description

The M45PE16 is a 16Mb(2Mb ×8) serial Flash memory device accessed by a high-speed, SPI-compatible bus.\r
\r
The memory can be written or programmed 1 to 256 bytes at a time using the PAGE WRITE or PAGE PROGRAM command. The PAGE WRITE command consists of an inte-grated PAGE ERASE cycle followed by a PAGE PROGRAM cycle.\r
\r
The memory is organized as 32 sectors, each containing 256 pages. Each page is 256 bytes wide. The entire memory can be viewed as consisting of 8192 pages, or 2,097,152 bytes.\r
\r
The memory can be erased one page at a time using the PAGE ERASE command or one sector at a time using the SECTOR ERASE command.\r
\r
To meet environmental requirements, Micron offers the M45PE16 in RoHS-compliant packages, which are also lead-free.\r
\r
Delivery of parts operating with a maximum clock rate of 75 MHz begins week 8 of 2008.
