STM32F2 Series 

STM32 F2 series of high-performance MCUs
The ARM® Cortex™-M3-based STM32 F2 series uses ST’s advanced 90 nm NVM process technology with the innovative adaptive real-time memory accelerator (ART Accelerator™) and multi-layer bus matrix. This offers an unprecedented trade-off in price and performance.
The series is characterized by a high degree of integration combining up to 1 Mbyte of Flash memory and up to 128 Kbytes of SRAM with Ethernet MAC, USB 2.0 HS OTG, camera interface, hardware encryption support and external memory interface.
ST’s acceleration technology enables these MCUs to achieve up to 150 DMIPS/398 CoreMark at 120 MHz FCPU, which is equivalent to zero wait state execution, while keeping the dynamic current consumption at the outstandingly low level of
175 µA/MHz.
The devices are available in LQFP64, LQFP100, LQFP144, WLCSP66 (< 4 x 4 mm), UFBGA176 and LQFP176 packages.
The series consists of two product lines which are fully pin-to-pin, peripheral and software compatible. The series also offers close pin-to-pin compatibility with the other STM32 products.
STM32F205/215 – 120 MHz CPU/150 DMIPS, up to 1 Mbyte of Flash with advanced connectivity and encryption
STM32F207/217 – 120 MHz CPU/150 DMIPS, up to 1 Mbyte of Flash with advanced connectivity and encryption, adding Ethernet MAC and camera interface to the STM32F205/215, and more GPIOs and features on larger packages

STM32F2x7  

ST’s STM32F207/217 devices 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 10 x 10 mm are required.
Performance: At 120 MHz, the STM32F207/217 deliver 150 DMIPS/398 CoreMark performance executing from Flash memory, with 0-wait states using ST’s ART Accelerator.
Power efficiency: ST’s 90 nm process, ART Accelerator and the dynamic power scaling enables the current consumption in run mode and executing from Flash memory to be as low as 175 µA/MHz at 120 MHz.
Rich connectivity: Superior and innovative peripherals
Compared with the STM32F205/215 devices, the STM32F207/217 add the Ethernet MAC10/100 with IEEE 1588 v2 support and an 8- to 14-bit parallel camera interface to connect a CMOS camera sensor
2x USB OTG (one with HS support)
Audio: dedicated audio PLL and 2 half duplex I²S
Up to 15 communication interfaces (including 6 USARTs running at up to 7.5 Mbit/s, 3x SPI running at up to 30 Mbit/s,
3x I²C, 2x CAN, SDIO)
Analog: two 12-bit DACs, three 12-bit ADCs reaching 2 MSPS or 6 MSPS in interleaved mode
Up to 17 timers: 16- and 32-bit timers
Easily extendable memory range using the flexible static memory controller supporting Compact Flash, SRAM, PSRAM, NOR and NAND memories
Analog true random number generator
The STM32F217 also integrates a crypto/hash processor providing hardware acceleration for AES 128, 192, 256,
Triple DES, and hash (MD5, SHA-1)
The STM32F207/217 devices cover from 256 Kbytes to 1 MByte of Flash, 128 Kbytes of SRAM and from 100 to 176 pins in packages as small as 10 x 10 mm.
