HM25Q128A 3V 128M-BIT SERIAL NOR FLASH WITH DUAL AND QUAD SPI&QPI
The SPI protocols use only 4 to 6 signals:
■Chip Select (CS#)
■Serial Clock (CLK)
■Serial Data
◆IO0 (DI)
◆IO1 (DO)
◆IO2 (WP#)
◆IO3 (HOLD# / RESET#)
The HM25Q128A support the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI as well as2-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 all owing 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.
