GENERAL DESCRIPTION

The XM25QH128A is a 128 Megabit (16,384K-byte) Serial Flash memory, with advanced write

protection mechanisms. The XM25QH128A supports the single bit and four bits serial input and output

commands via standard Serial Peripheral Interface (SPI) pins: Serial Clock, Chip Select, Serial DQ0 (DI)

and DQ1(DO), DQ2(WP#) and DQ3(HOLD#/RESET#). SPI clock frequencies of up to 104Mhz are

supported allowing equivalent clock rates of 416Mhz(104Mhz x 4) for Quad Output while using the Quad

Output read instructions. The memory can be programmed 1 to 256 bytes at a time, using the Page

Program instruction.

The XM25QH128A also offers a sophisticated method for protecting individual blocks against erroneous

or malicious program and erase operations. By providing the ability to individually protect and unprotect

blocks, a system can unprotect a specific block to modify its contents while keeping the remaining

blocks of the memory array securely protected. This is useful in applications where program code is

patched or updated on a subroutine or module basis or in applications where data storage segments

need to be modified without running the risk of errant modifications to the program code segments.

The XM25QH128A is designed to allow either single Sector/Block at a time or full chip erase operation.

The XM25QH128A can be configured to protect part of the memory as the software protected mode.

The device can sustain a typical of 100K program/erase cycles on each sector or block.
