The STM32F730 and STM32F750 Value lines offer the performance of the Arm® Cortex®-M7 core (with floating point unit) running up to 216 MHz at an affordable price point by trimming embedded Flash to the essential. The STM32F7x0 Value lines offer the lowest price point ever for the STM32F7 Series.

Performance

At 216 MHz fCPU, the STM32F7x0 line delivers 1082 CoreMark / 462 DMIPS performance executing from Flash memory, with 0-wait states thanks to ST’s ART Accelerator. The FPU and DSP instructions enlarge the range of addressable applications. External memory can be used with no performance penalty thanks to the L1 cache (I/D up to 8 Kbytes + 8 Kbytes).

Power efficiency

ST’s 90 nm process, ART Accelerator™ and dynamic power scaling enables the power consumption in Run mode and executing from Flash memory to be at 7 CoreMark / mW at 1.8 V.

In Stop mode, power consumption is typically 100 µA.

The maximum junction temperature supported is up to 125 °C, allowing to leverage the full core and peripherals performance even when the ambient temperature increases.

Graphics

The STM32F750 line includes an LCD-TFT controller interface with dual-layer support that takes advantage of the Chrom‑ART Accelerator™. This graphics accelerator creates content twice as fast as the core alone. As well as efficient 2-D raw data copy, additional functions 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 the processing bandwidth of the MCU core for other applications.

Integration

Audio: Two dedicated audio PLLs, three half-duplex I²S interfaces and a new serial audio interface (SAI) supporting time-division multiplex (TDM) mode.
Up to 25 communication interfaces (including four USARTs in addition to four UARTs running at up to 12.5 Mbit/s, up to six SPIs running at up to 50 Mbit/s, up to four I²C interfaces with a new optional digital filter capability, up to two CAN, up  to two SDMMC, USB 2.0 full-speed device/host/OTG controller with an optional on-chip PHY and a USB 2.0 high-speed/full-speed device/host/OTG controller (with on-chip high-speed PHY), optional SPDIF-IN and optional HDMI-CEC.

Analog: Two 12-bit DACs, three 12-bit ADCs reaching 2.4 Msample/s or 7.2 Msample/s in Interleaved mode.
Up to eighteen 16- and 32-bit timers running at up to 216 MHz.
Easily extendable memory range using the flexible memory controller with 32-bit parallel interface, and supporting Compact Flash, SRAM, PSRAM, NOR, NAND and SDRAM memories or using the Dual-mode Quad-SPI Flash memory interface to allow code execution from an external serial Flash memory.
An analog true random number generator.

Security

The STM32F7x0 line comes with the proprietary code read-out-protection feature and integrates a crypto processor providing hardware acceleration for AES-128 and -256 encryption.

The STM32F7x0 line integrates a crypto/hash processor providing hardware acceleration for AES-128, -192 and -256 encryption, with support for GCM and CCM, Triple DES, and hash (MD5, SHA-1 and SHA-2) algorithms.

The STM32F7x0 Value line provides 64 Kbytes of Flash memory and 320 Kbytes of SRAM including up to 64 Kbytes of Tightly-Coupled Memory for Data (DTCM), 16 Kbytes of Tightly-Coupled Memory for Instructions (ITCM), and 4-Kbyte Backup RAM, in LQFP64, LQFP100, LQFP144 ,UFBGA 176-and TFBGA216 pin packages.
