GENERAL DESCRIPTION
The EN25Q32A is a 32 Megabit (4096K-byte) Serial Flash memory, with advanced write protection
mechanisms. The EN25Q32A 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 EN25Q32A is designed to allow either single Sector/Block at a time or full chip erase operation. The
EN25Q32A 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.
