The HM25Q128A support the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI as well as

2-clocks instruction cycle Quad Peripheral Interface (QPI): Serial Clock, Chip Select, Serial Data I/O0 (DI),

I/O1 (DO), I/O2 (WP#), and I/O3 (HOLD# / RESET#). SPI clock frequencies of up to 104MHz are supported

allowing equivalent clock rates of 208MHz (104MHz x 2) for Dual I/O and 416MHz (104MHz x 4) for Quad I/O

when using the Fast Read Dual/Quad I/O and QPI instructions. These transfer rates can outperform standard

Asynchronous 8 and 16-bit Parallel Flash memories. The Continuous Read Mode allows for efficient memory

access with as few as 8-clocks of instruction-overhead to read a 24-bit address, allowing true XIP (execute in

place) operation.

A Hold pin, Write Protect pin and programmable write protection, with top or bottom array control, provide

further control flexibility. Additionally, the device supports JEDEC standard manufacturer and device ID and

SFDP Register, a 64-bit Unique Serial Number and three 256-bytes Security Registers.

The

HM25Q128A

provides an ideal storage solution for systems with limited space, signal connections,

and power. These memories' flexibility and performance is better than ordinary serial flash devices. They are

ideal for code shadowing to RAM, executing code directly (XIP), and storing reprogrammable data.
