STMicroelectronics STM32F207ICH6

Overview

STM32F207ICH6 from STMicroelectronics is a 32-bit Arm® Cortex®-M3 microcontroller operating at up to 120 MHz, featuring 1 MB Flash, 128 + 4 KB SRAM, dual CAN 2.0B interfaces, 10/100 Ethernet MAC with IEEE 1588v2 hardware support, and USB OTG HS/FS controllers - deployed in industrial gateways requiring real-time protocol bridging and deterministic network timing.

For engineers reviewing the STM32F207ICH6 datasheet, STM32F207ICH6 pinout, STM32F207ICH6 application, or STM32F207ICH6 equivalent, key selection considerations include Ethernet MAC+DMA co-processing capability, dual-CAN bus arbitration latency, ART Accelerator™-enabled zero-wait-state Flash execution, and LQFP64 package I/O count versus peripheral mapping constraints.

Technical Context

The device integrates a Cortex-M3 core with Memory Protection Unit (MPU), Adaptive Real-Time Accelerator (ART) for deterministic Flash access, and multi-AHB bus matrix enabling concurrent access to Flash, SRAM, FSMC, and peripherals. It supports full-speed and high-speed USB OTG via dedicated DMA channels and on-chip PHYs.

Its Ethernet MAC implements MII/RMII physical layer interfaces with hardware timestamping for IEEE 1588v2 precision time protocol, while dual CAN controllers operate independently with programmable bit timing and message filtering - critical for automotive diagnostics and industrial fieldbus gateways.

FAQ

Does STM32F207ICH6 support hardware encryption acceleration?

No, STM32F207ICH6 does not include a dedicated cryptographic processor or AES engine. It features a True Random Number Generator (RNG) and CRC calculation unit for integrity checks, but symmetric encryption (e.g., AES) must be implemented in software using its Cortex-M3 core and SRAM resources.

What is the maximum achievable Ethernet throughput with STM32F207ICH6's MAC?

The Ethernet MAC supports 10/100 Mbps line rate with full-duplex operation. Real-world throughput is limited by DMA bandwidth and SRAM buffer size - measured benchmarks show sustained 65–75 Mbps UDP transfer with zero packet loss under optimized FreeRTOS+TCP stack configuration and 32 KB RX/TX descriptors.

Can STM32F207ICH6 drive a 16-bit parallel LCD without external logic?

Yes - its LCD parallel interface supports 8080/6800 modes with up to 16-bit data bus width and integrated timing generators. In LQFP64, 16-bit mode uses PA0–PA15 and PB0–PB1, requiring careful pin multiplexing since those pins also serve as ADC inputs and timer channels.

Is the USB OTG HS interface functional in LQFP64 package?

No - USB OTG High-Speed functionality requires ULPI interface signals (ULPI_CLK, ULPI_Dx, ULPI_DIR, etc.) not routed to LQFP64 pins. Only USB OTG Full-Speed (with on-chip PHY) is available in this package; HS operation requires LQFP100 or larger packages with ULPI pinout.
