STMicroelectronics has announced a new evaluation kit for its STM32H5 microcontroller — the company's first kit to include support for the STMicro's Secure Manager system-on-chip security functionality.
The STM32H573I-DK Discovery Kit, to give STMicro's latest launch its full name, is designed for those looking to experiment with the functions available from the company's STM32H5 microcontroller family — including the "ST ART Adaptive Real-Time Accelerator," designed to speed up instruction fetch accesses between the part's Arm Cortex-M33 processor core, running at up to 250MHz, and internal memories.
Accelerator aside, the STM32H5 is also notable as being STMicro's first microcontroller part to include Secure Manager, a system-on-chip security platform which combines Arm's TrustZone technology with STMicro's own STM32Trust framework for trusted storage, cryptographic operations, attestation, and secure updates — as well as providing embedded protection against side-channel attacks, the company claims.
Use of the STM32H5 makes the new STM32H573I-DK Discovery Kit the first evaluation board to ship with Secure Manager support, but it has plenty of other features besides. The kit includes a STM32H573IIK3Q with Arm Cortex-M33 running at up to 250MHz, 640kB of static RAM (SRAM), and 2MB of flash, a 1.54" 240×240 color touchscreen display, a USB 2.0 port with 15W sink-or-source support, a Fast Ethernet port, a MEMS digital microphone and SAI audio codec, an 802.11b/g/n Wi-Fi module, and four user-addressable LEDs.
For connectivity, the board includes a Tag-Connect 10-pin footprint, Arm Cortex SWD/JTAG debug connector, STMod+ and Pmod expansion, and an Arduino UNO-compatible pin header. On the software front, STMicro is providing STM32CubeH5 — including examples and application code for the STM32H5 family. For configuration and initialization, there's also STM32CubeMX.
The STM32H573I-DK Discovery Kit is listed on STMicro's store at $96.78, though at the time of writing was showing as out of stock.
