For more details on the whole STMicroelectronics STM32 family, please refer to Section 2.1: Full compatibility throughout the family. The STM32F427xx and STM32F429xx datasheet should be read in conjunction with the STM32F4xx reference manual. For information on the Cortex®-M4 core, please refer to the Cortex®-M4 programming manual (PM0214), available from www.st.com. DocID024030 Rev 10 13/239 44 Description 2 STM32F427xx STM32F429xx Description The STM32F427xx and STM32F429xx devices are based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 180 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all Arm® singleprecision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. The STM32F427xx and STM32F429xx devices incorporate high-speed embedded memories (Flash memory up to 2 Mbyte, up to 256 Kbytes of SRAM), up to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix. All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose 16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers. They also feature standard and advanced communication interfaces. • Up to three I2Cs • Six SPIs, two I2Ss full duplex. To achieve audio class accuracy, the I2S peripherals can be clocked via a dedicated internal audio PLL or via an external clock to allow synchronization. • Four USARTs plus four UARTs • An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the ULPI), • Two CANs • One SAI serial audio interface • An SDIO/MMC interface • Ethernet and camera interface • LCD-TFT display controller • Chrom-ART Accelerator™. Advanced peripherals include an SDIO, a flexible memory control (FMC) interface, a camera interface for CMOS sensors. Refer to Table 2: STM32F427xx and STM32F429xx features and peripheral counts for the list of peripherals available on each part number. The STM32F427xx and STM32F429xx devices operates in the –40 to +105 °C temperature range from a 1.7 to 3.6 V power supply. The supply voltage can drop to 1.7 V with the use of an external power supply supervisor (refer to Section 3.17.2: Internal reset OFF). A comprehensive set of power-saving mode allows the design of low-power applications. The STM32F427xx and STM32F429xx devices offer devices in 8 packages ranging from 100 pins to 216 pins. The set of included peripherals changes with the device chosen. 14/239 DocID024030 Rev 10 STM32F427xx STM32F429xx Description These features make the STM32F427xx and STM32F429xx microcontrollers suitable for a wide range of applications: • Motor drive and application control • Medical equipment • Industrial applications: PLC, inverters, circuit breakers • Printers, and scanners • Alarm systems, video intercom, and HVAC • Home audio appliances Figure 4 shows the general block diagram of the device family.

For the LQFP100 package, only FMC Bank1 or Bank2 are available. Bank1 can only support a multiplexed NOR/PSRAM memory using the NE1 Chip Select. Bank2 can only support a 16- or 8-bit NAND Flash memory using the NCE2 Chip Select. The interrupt line cannot be used since Port G is not available in this package. For UFBGA169 package, only SDRAM, NAND and multiplexed static memories are supported. 2. The SPI2 and SPI3 interfaces give the flexibility to work in an exclusive way in either the SPI mode or the I2S audio mode. 3. VDD/VDDA minimum value of 1.7 V is obtained when the device operates in reduced temperature range, and with the use of an external power supply supervisor (refer to Section 3.17.2: Internal reset OFF).

STM32F427xx and STM32F429xx features and peripheral counts (continued) Description 17/239 Description 2.1 STM32F427xx STM32F429xx Full compatibility throughout the family The STM32F427xx and STM32F429xx devices are part of the STM32F4 family. They are fully pin-to-pin, software and feature compatible with the STM32F2xx devices, allowing the user to try different memory densities, peripherals, and performances (FPU, higher frequency) for a greater degree of freedom during the development cycle. The STM32F427xx and STM32F429xx devices maintain a close compatibility with the whole STM32F10xx family. All functional pins are pin-to-pin compatible. The STM32F427xx and STM32F429xx, however, are not drop-in replacements for the STM32F10xx devices: the two families do not have the same power scheme, and so their power pins are different. Nonetheless, transition from the STM32F10xx to the STM32F42x family remains simple as only a few pins are impacted. Figure 1, Figure 2, and Figure 3, give compatible board designs between the STM32F4xx, STM32F2xx, and STM32F10xx families. Figure 1.
