ZB25VQ32D Description/概述：
The ZB25VQ32D of non-volatile flash memory device supports the standard Serial Peripheral Interface (SPI). Traditional SPI single bit serial input and output (Single I/O or SIO) is supported as well as optional two bit (Dual I/O or DIO) and four bit (quad I/O or QIO) serial protocols. This multiple width interface is called SPI Multi-I/O or MIO.
The ZB25VQ32D 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 133MHz are supported allowing equivalent clock rates of 266MHz (133MHz x 2) for Dual I/O and 532MHz (133MHz 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 128-bit Unique Serial Number and three 1024-Byte Security Registers.The ZB25VQ32D 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.
ZB25VQ32D非易失性閃存設備支持標準串行外設接口（SPI）支持傳統(tǒng)的SPI單位串行輸入和輸出（單I/O或SIO）以及可選的兩個位（雙I/O或DIO）和四位（四I/O或QIO）串行協(xié)議。這種多寬度接口稱為SPI多I/O或MIO。
ZB25VQ32D支持標準串行外設接口（SPI）、雙/四路I/O SPI以及2塊指令周期四外設接口（QPI）：串行時鐘，芯片選擇，串行數(shù)據(jù)I/O 0（DI），I/O1（DO）、I/O2（WP#）和I/O3（保持#/RESET#）。支持高達133MHz的SPI時鐘頻率允許雙輸入/輸出的等效時鐘頻率為266MHz（133MHz x 2），四輸入/輸出為532MHz（133MHz x 4）當使用快速讀取雙/四路I/O和QPI指令時。這些傳輸速率可以優(yōu)于標準傳輸速率異步8位和16位并行閃存。連續(xù)讀取模式允許高效存儲只需8個時鐘的指令開銷即可讀取24位地址，從而實現(xiàn)真正的XIP（在場所）操作。
保持引腳、寫入保護引腳和可編程寫入保護，具有頂部或底部陣列控制，提供進一步的控制靈活性。此外，該設備支持JEDEC標準制造商和設備ID以及SFDP寄存器、一個128位唯一序列號和三個1024字節(jié)安全寄存器。ZB25VQ32D為具有有限空間、信號連接等的系統(tǒng)提供了理想的存儲解決方案，和權力。這些存儲器的靈活性和性能都優(yōu)于普通的串行閃存設備。他們是非常適合將代碼隱藏到RAM、直接執(zhí)行代碼（XIP）和存儲可編程數(shù)據(jù)。
