GENERAL DESCRIPTION
The EN25F20A is a 2 Megabit (256 K-byte) Serial Flash memory, with enhanced write protection
mechanisms. The EN25F20A supports the standard Serial Peripheral Interface (SPI), and a high
performance Dual/Quad output as well as Dual/Quad I/O using SPI pins: Serial Clock, Chip Select,
Serial DQ
0
(DI), DQ
1
(DO), DQ
2
(WP#) and DQ
3
(HOLD#). SPI clock frequencies of up to 104MHz are
supported allowing equivalent clock rates of 208MHz (104MHz x 2) for Dual Output and 416MHz
(104MHz x 4) for Quad Output when using the Dual/Quad I/O Fast Read instructions. The memory can
be programmed 1 to 256 bytes at a time, using the Page Program instruction.
The EN25F20A is designed to allow either single
Sector/Block
at a time or full chip erase operation. The
EN25F20A 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.
