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.
