GENERAL DESCRIPTION
The EN25Q80A is an 8 Megabit (1024K-byte) Serial Flash memory, with advanced write protection
mechanisms. The EN25Q80A 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 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 EN25Q80A is designed to allow either single Sector/Block at a time or full chip erase operation. The
EN25Q80A 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.

MEMORY ORGANIZATION
The memory is organized as:
z 1,048,576 bytes
z Uniform Sector Architecture
16 blocks of 64-Kbyte
256 sectors of 4-Kbyte
z 4096 pages (256 bytes each)
Each page can be individually programmed (bits are programmed from 1 to 0). The device is Sector,
Block or Chip Erasable but not Page Erasable.
