GENERAL DESCRIPTION

The EN25Q64 is a 64 Megabit (8192K-byte) Serial Flash memory, with advanced write protection
mechanisms. The EN25Q64 supports the standard Serial Peripheral Interface (SPI), and a high
performance Dual output as well as Quad I/O using SPI pins: Serial Clock, Chip Select, Serial DQ0(DI),
DQ1(DO), DQ2(WP#) and DQ3(NC). SPI clock frequencies of up to 50MHz are supported allowing
equivalent clock rates of 100MHz for Dual Output and 200MHz for Quad Output when using the
Dual/Quad Output Fast Read instructions. The memory can be programmed 1 to 256 bytes at a time,
using the Page Program instruction.
The EN25Q64 is designed to allow either single Sector/Block at a time or full chip erase operation. The
EN25Q64 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.
