这不是真的！ STM32H7单颗价格不到19.9 ...
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：

（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

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
The latest additions to the STM32* family, the STM32F7x0 and H7x0 Value Line microcontrollers (MCU) from STMicroelectronics, give extra flexibility to create affordable performance-oriented systems including real-time IoT devices, without compromising features or cyber protection.
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.

这个价格有点不敢相信:lol 马上买片子做啊 Prices start from $1.64 for the STM32F730, $2.39 for the STM32F750 and $2.69 for the STM32H750 for orders of 1000 pieces.
在 stm32cubeMX上查，还没这几个芯片 so the truth is? 19.9人民币？？ 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.
这是真的？
64-pin——240-pin
STM32F730$1.64
STM32F750$2.69
确定是7x0不是1x0?
这个价格真是劲爆。 签到 ST这性能和价格对国产MCU是一大冲击啊
