GENERAL DESCRIPTION
The EN25QH32 is a 32 Megabit (4,096 K-byte) Serial Flash memory, with enhanced write protection
mechanisms. The EN25QH32 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 80MHz are
supported allowing equivalent clock rates of 160MHz (80MHz x 2) for Dual Output when using the Dual
Output Fast Read instructions, and SPI clock frequencies of up to 50MHz are supported allowing
equivalent clock rates of 200MHz (50MHz x 4) for Quad Output when using the Quad Output Fast
Read instructions. The memory can be programmed 1 to 256 bytes at a time, using the Page Program
instruction.
The EN25QH32 is designed to allow either single
Sector/Block
at a time or full chip erase operation.
The EN25QH32 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
.
