STMicroelectronics STM32F215RGT6TR

Overview

STM32F215RGT6TR from STMicroelectronics is a high-performance ARM Cortex-M3 microcontroller featuring 120 MHz CPU, 1 MB Flash, 128+4 KB SRAM, hardware crypto acceleration (AES-256, SHA-1), USB OTG HS/FS, 10/100 Ethernet MAC with IEEE 1588v2 support, and dual CAN 2.0B interfaces - deployed in industrial gateways requiring secure connectivity and real-time protocol bridging.

For engineers reviewing the STM32F215RGT6TR datasheet, STM32F215RGT6TR pinout, STM32F215RGT6TR application, or STM32F215RGT6TR equivalent, key selection criteria include cryptographic co-processor support, dual USB PHY integration (FS + HS), Ethernet MAC with hardware timestamping, parallel camera interface bandwidth (48 MB/s), and 138 5 V-tolerant I/Os for mixed-voltage system interfacing.

Technical Context

The STM32F215RGT6TR implements an ARM Cortex-M3 core with Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from Flash at 120 MHz. Its memory subsystem includes 1 MB Flash with ECC, 128 KB main SRAM plus 4 KB backup SRAM, and a flexible static memory controller supporting NAND/NOR/PSRAM.

Peripherals are organized across three AHB domains and two APB buses, with dedicated DMA channels for high-bandwidth interfaces: Ethernet MAC (with IEEE 1588v2 hardware timestamping), USB OTG HS (with ULPI and on-chip FS PHY), and DCMI (8–14-bit parallel, up to 48 MB/s). The crypto engine integrates AES-128/192/256, Triple DES, and HASH (MD5/SHA-1) accelerators alongside an analog true RNG.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F215RGT6TR achieves 120 MHz maximum CPU frequency using the ARM Cortex-M3 core with Adaptive Real-time Accelerator (ART) - a 6-stage prefetch buffer and branch cache that eliminates Flash wait states. This allows deterministic 0-wait-state execution directly from 1 MB embedded Flash memory, validated across temperature and voltage ranges per datasheet Section 6.3.1.

Does this MCU support hardware-accelerated SHA-1 and AES-256?

Yes. The STM32F215RGT6TR integrates a dedicated cryptographic processor supporting AES-128/192/256, Triple DES, and HASH algorithms including MD5 and SHA-1 - confirmed in Section 3.31.1 of the datasheet. It also includes an analog true random number generator (RNG) compliant with NIST SP800-90B for key derivation.

Can the Ethernet MAC operate in IEEE 1588v2 Precision Time Protocol mode?

Yes. The integrated 10/100 Ethernet MAC includes hardware timestamping registers for IEEE 1588v2 PTP, enabling sub-microsecond packet timestamping at both ingress and egress. This is documented in Section 3.26 and electrical specs Table 61–62, with register-level control defined in the Reference Manual RM0033.

What camera sensors are compatible with the DCMI interface?

The 8–14-bit parallel DCMI supports standard CMOS image sensors with embedded sync signals (VSYNC/HSYNC/PCLK), including OV5640 (5 MP), OV7670 (VGA), and MT9V034 (global shutter). Maximum 48 MB/s bandwidth and programmable data capture polarity (Section 3.31) ensure compatibility with common industry sensors without external FIFOs or FPGAs.
