STM32H7B0 Value line

The STM32H7B0 Value line contains an Arm^® Cortex^®-M7 core (with double-precision floating point unit) which runs up to 280 MHz. The embedded Flash memory of 128 Kbytes allows ST to offer a cost-efficient solution for developers.

Performance

• 280 MHz f_CPU/, 1414 CoreMark /599 DMIPS executing from Flash memory, with 0-wait states thanks to its L1 cache.
• 128 Kbytes of embedded Flash organized in 8 Kbytes sectors for user root of trust, critical real time routines execution and easy configuration of external memories.
• L1 cache (16 Kbytes of I-cache +16 Kbytes of D-cache) boosting execution performance from external memories.

Security

The STM32H7B0 integrates:

• Crypto/hash hardware acceleration
• On-the-fly decryption on Octo-SPI external serial flash memory
• Secure Firmware Install (SFI) embedded security services to authenticate and protect your software IPs while performing initial programming.
• Secure Boot Secure Firmware Update (SBSFU)

Power efficiency

• Dual-power domain architecture enables each power domain to be set in low-power mode to optimize power efficiency.
• Embedded SMPS to scale supply voltage down. It can also be used to supply external circuitry and can also be combined with the LDO for specific use cases.
• 120 µA/MHz typical @VDD = 3.3 V and 25 °C in Run mode (peripherals off) and SMPS

Graphics

• LCD-TFT controller interface with dual-layer support
• Chrom‑ART Accelerator™ boosts graphical content creation while saving core processing power, thus freeing up the MCU for other application needs
• Chrom-GRC™ optimizes RAM use
• JPEG hardware accelerator for fast JPEG encoding and decoding, off-loading the CPU.

Embedded peripherals

• Up to 35 communication interfaces including FD-CAN, USB 2.0 high-speed/full-speed, camera interface, Parallel synchronous data input/output slave interface (PSSI)
• Easily extendable external memories using the flexible memory controller with a 32-bit parallel interface supporting, SRAM, PSRAM, NOR, NAND and SDRAM memories, or the Dual-mode Quad-SPI serial Flash memory interface.
• Analog:  Dual 16-bit ADCs
• Multiple 16- and 32-bit timers running at up to 280 MHz

The STM32H7B0 Value line provides 128 Kbytes of Flash memory, 1.4 Mbytes of SRAM with a scattered architecture: 192 Kbytes of TCM RAM (including 64 Kbytes of ITCM RAM and 128 Kbytes of DTCM RAM for time-critical routines and data), 1.18 Mbytes of user SRAM, and 4 Kbytes of SRAM in backup domain to keep data in the lowest power modes and 64- to 176-pin packages in BGA and LQFP profiles.
