●General Description
●The S25FL204K (4-Mbit, 512-kbyte) Serial Flash memory, with advanced write protection mechanisms. TheS25FL204K supports the standard Serial Peripheral Interface (SPI), and a high performance Dual output using SPI pins: Serial Clock, Chip Select, Serial SI/IO0, SO, WP# and HOLD#. SPI clock frequencies of up to 85 MHz are supported along with a clock rate of 85 MHz for Dual Output Read.
●The S25FL204K array is organized into 2048 programmable pages of 256 bytes each. Up to 256 bytes can be programmed at a time. Pages can be erased in groups of 16 (4 kB Sector Erase), groups of 256 (64 kB Block Erase) or the entire chip (Chip Erase). The S25FL204K has128 erasable sectors and 8 erasable blocks. The small 4 kB sectors allow for greater flexibility in applications that require data and parameter storage.
●A Hold pin, Write Protect Pin and programmable write protection provide further control flexibility. Additionally, the S25FL204K device supports JEDEC standard manufacturer and device identification.
