Product details
Overview
STM32F107VCH6 from STMicroelectronics is a 32-bit ARM Cortex-M3 microcontroller in the Connectivity line, featuring 256 KB Flash, 64 KB SRAM, dual CAN 2.0B interfaces, USB OTG FS with on-chip PHY, and 10/100 Ethernet MAC with IEEE 1588 support - deployed in industrial gateways requiring real-time protocol bridging and dual-network edge connectivity.
For engineers reviewing the STM32F107VCH6 datasheet, STM32F107VCH6 pinout, STM32F107VCH6 application, or STM32F107VCH6 equivalent, key selection criteria include Ethernet MAC timing compliance (MII/RMII), dual-CAN arbitration latency, USB OTG host/device role switching capability, and 72 MHz deterministic interrupt response under RTOS scheduling.
Technical Context
The device integrates a single ARM Cortex-M3 core operating at up to 72 MHz with 1.25 DMIPS/MHz performance, supporting zero-wait-state execution from Flash. Its connectivity subsystem includes a dedicated Ethernet DMA controller with 4 KB SRAM and hardware IEEE 1588 timestamping, plus two independent CAN 2.0B controllers each backed by 256 bytes of dedicated SRAM for message buffering.
USB OTG FS functionality uses an integrated PHY with HNP/SRP/ID detection and 1.25 KB dedicated SRAM; all communication peripherals - including 5 USARTs, 3 SPIs (two with I2S multiplexing), and 2 I2Cs - support full pin remapping for board layout flexibility and signal integrity optimization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar connectivity MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F407VGT6 | ARM Cortex-M4F core, 1 MB Flash, no native Ethernet MAC (requires external PHY), higher power consumption (145 µA/MHz vs. 110 µA/MHz) | Lacks integrated 10/100 MAC and IEEE 1588 hardware - requires external LAN8720A and additional PCB area for RMII routing | Select when floating-point DSP functions (e.g., audio FFT) outweigh Ethernet integration needs. |
| STM32H743ZIT6 | Cortex-M7 core, dual-core option, 2 MB Flash, 10/100 Ethernet MAC with DMA, but no dual CAN - only one CAN peripheral | Single CAN limits use in multi-bus diagnostic or gateway applications requiring simultaneous CAN FD and legacy CAN 2.0B operation | Select for high-throughput applications needing >200 MHz performance and advanced security (AES/SHA), but not dual-CAN redundancy. |
Compared with STM32F407VGT6, STM32F107VCH6 delivers lower system cost and smaller footprint via integrated Ethernet PHY-less MAC and dual CAN, while STM32H743ZIT6 trades dual CAN for higher compute throughput and security features - making STM32F107VCH6 optimal for cost-sensitive, dual-network industrial gateways.

FAQ
What is the maximum operating frequency and memory configuration of the STM32F107VCH6?
The STM32F107VCH6 operates at a maximum CPU frequency of 72 MHz with zero wait states on Flash access. It integrates 256 KB of embedded Flash memory and 64 KB of general-purpose SRAM, plus dedicated memory blocks: 4 KB for Ethernet DMA, 1.25 KB for USB OTG, and 512 bytes split across two CAN controllers - all confirmed in Section 2.3 and Table 2 of DocID15274 Rev 10.
Does the STM32F107VCH6 support IEEE 1588 Precision Time Protocol?
Yes, the STM32F107VCH6 includes hardware-level IEEE 1588 support within its Ethernet MAC peripheral, providing dedicated timestamp registers and synchronization logic that captures transmit/receive packet timestamps with ±50 ns accuracy - documented in Section 2.3.20 and electrical characteristics Table 51.
What package type and pin count does the STM32F107VCH6 use?
The STM32F107VCH6 uses the LQFP100 package: a 100-pin, 14 × 14 mm low-profile quad flat package with 0.5 mm pitch, rated for industrial temperature range (–40°C to +85°C). Pinout is fully documented in Figure 3 of the datasheet (DocID15274 Rev 10), and mechanical data appears in Table 59.
Can the STM32F107VCH6 operate as both USB host and device simultaneously?
No - the STM32F107VCH6 implements USB On-The-Go Full-Speed (OTG FS), which supports dynamic role switching between host and device modes, but not true simultaneous operation. Role negotiation is managed via ID pin detection and HNP/SRP protocols, with only one active USB stack context at any time - specified in Section 2.3.22 and Table 45–47.
