M25P16 概述

The M25P16 is a 16 Mbit (2 Mbit × 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.

The memory is organized as 32 sectors, each containing 256 pages. Each page is 256 bytes wide. Thus, the whole memory can be viewed as consisting of 8192 pages, or 2097152 bytes.
