EN25S40 - Eon Silicon Solution

EN25S40 4 Megabit 1.8V Serial Flash Memory

The EN25S40 is a 4 Megabit (512K-byte) Serial Flash memory, with advanced write protection mechanisms. The EN25S40 supports the standard Serial Peripheral Interface (SPI), and a high performance Dual output as well as Dual I/O using SPI pins: Serial Clock, Chip Select, Serial DQ0(DI), DQ1(DO), WP# and HOLD#. SPI clock frequencies of up to 50MHz are supported.
