Description
The ACE25C200 is a 2M-bit (256K-byte) Serial Flash memory, with advanced write protection mechanisms. The ACE25C200 supports the standard Serial Peripheral Interface (SPI), and a high performance Dual output as well as Dual I/O.
The ACE25C200 can be programmed 1 to 256 bytes at a time, using the Page Program instruction. It is designed to allow either single Sector/Block at a time or full chip erase operation. The ACE25C200 can be configured to protect part of the memory as the software protected mode. The device can sustain a minimum of 100K program/erase cycles on each sector or block.
