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！
