GENERAL DESCRIPTION
The EN25Q40 is a 4 Megabit (512K-byte) Serial Flash memory, with advanced write protection
mechanisms. The EN25Q40 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 DQ
0
(DI),
DQ
1
(DO), DQ
2
(WP#) and DQ
3
(NC). SPI clock frequencies of up to 80MHz are supported allowing
equivalent clock rates of 160MHz for Dual Output and 320MHz 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 EN25Q40 is designed to allow either single
Sector/Block
at a time or full chip erase operation. The
EN25Q40 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
.
This Data Sheet may be revised by subsequent versions
or modifications due to changes in technical specifications.
