意法半导体全新高性能及超高性能的STM32超值产品线，推动实时物联网设备创新 今天上听小伙伴说，STM32H7芯片现货发售了，用 BOM2BUY 查了下，果然是真的，不信你看： http://www.bom2buy.com/search/STM32H7  （有图有真相） 然而，刚才看到的一篇文章更为劲爆，说STM32H7的价格要回到解放前啊 下面看文章怎么说： 意法半导体推出全新高性能和超高性能STM32超值系列，推动实时物联网设备创新 Geneva / 12 Jul 2018 These new lines trim embedded Flash to the essential, still allowing secure boot, sensitive code and real-time routines to run safely on-chip, leveraging access times over 25 times faster than for external Flash (for cache miss). If needed, applications can scale-up either by adding off-chip serial or parallel (up to 32-bit) memories and leveraging the MCUs’ broad external interfaces and eXecute in Place (XiP) capability, or by porting to other pin-to-pin compatible STM32F7 or STM32H7 MCU lines, with up to 2Mbyte Flash and up to 1Mbyte RAM, supported by the same ecosystem with the same easy-to-use tools. The Value Lines retain powerful STM32F7 and H7 features, such as the state-of-the-art peripherals, hardware accelerators, and the real-time architecture with ultra-fast internal buses, short interrupt latency, and fast (~1ms) boot-up. The MCUs are also energy efficient, with flexible power modes, gated power domains, and on-chip power management that simplify design and reduce BOM cost. 
With execution performance up to 2020 CoreMark® at the heart of a secure and power-efficient architecture, the new Value Line devices are the entry point to IoT innovation in medical, industrial, and consumer applications. With up to 125°C as the maximum junction temperature, developers can leverage the full core and peripherals performance even when ambient temperature increases. The entry-level STM32F730 delivers 1082 CoreMark performance running at 216MHz aided by ST’s unique ART Accelerator™ for zero-wait-state execution from Flash. Features include cryptographic hardware acceleration, a USB 2.0 High Speed port with PHY, and a CAN interface. There is a 64Kbyte Flash, 8KByte Instruction and data caches for high-performance execution from internal or external memories, 256KB of system RAM and 16kB+64KB of Tightly Coupled Memory (TCM) for the most critical routines and data. The STM32F750 adds a TFT-LCD controller with ST’s proprietary Chrom-ART™ Graphics Accelerator. It has hardware acceleration for hash algorithms, two CAN interfaces, an Ethernet MAC, camera interface, and two USB 2.0 interfaces with Full Speed PHY. There are 64Kbytes of Flash, 4Kbyte instruction and 4Kbyte data caches, 320KB of system RAM, and 16kB+64KB TCM. The high-endSTM32H750 delivers 2020 CoreMark performance at 400MHz and adds a hardware JPEG coder/decoder to the TFT controller and Chrom-ART Accelerator for even faster GUI performance. There is also a CANFD port and additional CANFD with time-trigger capability and best-in-class operational amplifiers and 16-bit ADCs running at up to 3.6Msample/s. The 128KByte Flash, 16KByte instruction and data caches, 864KByte system RAM and the 64kB+128KB of TCM all feature ECC (Error Correction Code) for safe execution from internal or external memory. The STM32F730, STM32F750, and STM32H750 Value Line MCUs are in production, in various LQFP and BGA package options from 64-pin to 240-pin. Prices start from $1.64 for the STM32F730, $2.39 for the STM32F750 and $2.69 for the STM32H750 for orders of 1000 pieces. 文章出处：（不敢乱说啊...） |

确定是7x0不是1x0?
可能你我理解的不一样，我查到的NOR FLASH不是SPI接口的，而是并口那样的。
而且网上并没有找到在W25QXX这类芯片里运行程序的描述，只是作为存储GUI的图片、字库等数据存取用途。
而我相信ST公司不会连这个行情都不知道，之前今年内听说FLASH芯片价格上涨带来的成本上升我觉得并没有包含W25QXX这类芯片。
w25qxx支持四线qspi 四线qspi是直接可以挂在总线上映射到mcu的地址空间视为内部闪存的。比如rt1052干脆没有闪存的mcu就是靠外挂这类闪存存储程序啊
点评
在 stm32cubeMX 上查，还没这几个芯片
点评
估计是要外挂FLASH的。
虽然是100PCS起售
人民币啊
