The 25D16 supports the standard Serial Peripheral Interface (SPI), and a high performance Dual output using SPI pins: Serial Clock, Chip Select, Serial DIO, DO, WP#. SPI clock frequencies of up to 105MHz are supported. The memory can be programmed 1 to 256 bytes at a time, using the Page Program instruction. The 25D16 also offers a sophisticated method for protecting individual blocks against erroneous or malicious program and erase operations. By providing the ability to individually protect and unprotect blocks, a system can unprotect a specific block to modify its contents while keeping the remaining blocks of the memory array securely protected. This is useful in applications where program code is...
