The STM32F429/439 lines are designed for medical, industrial and consumer applications where the high level of integration and performance, embedded memories and peripherals inside packages as small as 5 x 5.1 mm are required. The STM32F429/439 lines run at up to 180 MHz and deliver zero-wait performance from Flash reaching 225 DMIPS/606 Coremark. Superior and innovative peripherals Just like the STM32F427 line, the F429 product line features a rich set of peripherals for connectivity with new peripherals and features.
  • Graphics: The new TFT LCD controller interface with dual-layer support takes advantage of ST’s Chrom-ART graphics accelerator performing content creation twice as fast as the core alone. In addition to raw data copy, additional functionalities are supported by the Chrom-ART Accelerator such as image format conversion or image blending (image mixing with some transparency). As a result, the Chrom-ART Accelerator boosts graphics content creation and saves processing bandwidth of the MCU core for the rest of the application.
  • Audio: dedicated audio PLL, 2 full duplex I?S and a new serial audio interface (SAI) supporting time division multiplex (TDM) mode
  • More interfaces now available with up to 20 communication interfaces (including 4x USARTs plus 4x UARTs running at up to 11.25 Mbit/s, 6x SPI running at up to 42 Mbit/s, 3x I?C with a new optional digital filter capability, 2x CAN, SDIO
  • Analog: two 12-bit DACs, three 12-bit ADCs reaching 2.4 MSPS or 7.2 MSPS in interleaved mode
  • Up to 17 timers: 16- and 32-bit running at up to 180 MHz
You can easily extend your memory range using the flexible memory controller now reaching up to 84 MHz over up to a 32-bit parallel interface, and supporting Compact Flash, SRAM, PSRAM, NOR and NAND and now SDRAM memories. The STM32F439 also integrates a crypto/hash processor providing hardware acceleration for AES-128, -192 and -256, with support now for GCM and CCM, Triple DES, and hash (MD5, SHA-1, and now SHA-2), in addition to the analog true random number generator featured on all STM32F4 devices. The STM32F429 and F439 portfolio provides from 1-Mbyte dual-bank Flash/256-Kbyte SRAM to 2-Mbyte dual-bank Flash/256-Kbyte SRAM and from 100- to 216-pin packages. With such memory integration, the need for external memory is reduced, allowing smaller, safer and low-emission PCB designs.


 上面是F429/439的一些介绍。
180M主频，内置TFT驱动器，可以外挂SDRAM。多诱人啊

一个好的消息也就是keil最新出的4.72版本支持了STM32的429/439调试。一开始我调试的时候，还需要外挂ST提供的驱动才可编程，
这样子，对大家的调试会极为方便的。

上传一份datasheet，供大家参考。关于寄存器以及库函数，目前st官方还没有对外发布，我自己倒是有一份，但目前不能对外公布，因为还是内测当中。

这边要说明一下，如果有公司对此芯片感兴趣的，可以加我的qq，跟我沟通，可以和我联系，我可以协助您进行申请样品。一定要是公司哦，个人目前还不好操作，有不足的地方，请原谅呀！

关键是价格,呵呵
像现在的F4这样,大于50元以上,很难提起大家的兴趣啊...

---------------------------------
F4现在很多客户在用了哦。只要用的人多，价格一定会下来的，这肯定是必然的。

确实是个矛盾.
客户想要价格低才用.
供应商想要人用的多才能降价.

看谁先妥协,呵呵.

75元很贵吗？能满足高端点儿的要求，就不贵，选啥芯片要看需求。
