Product details
Overview
STM32F107VCT6 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 controller 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 STM32F107VCT6 datasheet, STM32F107VCT6 pinout, STM32F107VCT6 application, or STM32F107VCT6 equivalent, key selection criteria include Ethernet MAC timing compliance, dual-CAN arbitration latency, USB OTG host/device mode switching time, and 72 MHz deterministic interrupt response under concurrent peripheral DMA loads.
Technical Context
The device integrates a single ARM Cortex-M3 core running at up to 72 MHz with hardware division and single-cycle multiplication, coupled with nested vectored interrupt controller (NVIC) supporting 68 maskable interrupts. Its memory subsystem includes 256 KB of Flash with 2-cycle access at full speed and 64 KB of SRAM with bit-band aliasing for atomic peripheral register access.
Connectivity peripherals are architecturally decoupled: the 10/100 Ethernet MAC uses dedicated 4 KB SRAM and DMA channels isolated from USB OTG's 1.25 KB SRAM, while both CAN controllers feature 512 bytes of dedicated SRAM and independent message RAM allocation - enabling simultaneous real-time CAN FD-legacy bridging and TCP/IP stack execution without bus contention.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar connectivity microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F107VBT6 | Same core/peripherals but 100-pin LQFP with 64 KB Flash (vs. 256 KB); identical pinout and package. | Limited firmware footprint capacity; unsuitable for full-featured Ethernet+USB+CAN protocol stacks. | Select when application requires only basic TCP/IP + single CAN and firmware size <64 KB. |
| STM32F407VGT6 | ARM Cortex-M4F core @ 168 MHz, FPU, 1 MB Flash, same LQFP100 package; adds SDRAM controller and enhanced crypto. | Higher compute headroom for TLS encryption, audio codecs, or complex motion algorithms; no IEEE 1588 hardware support. | Select when application demands floating-point math, secure boot, or >256 KB code space - accepts trade-off of missing hardware timestamping. |
Compared with STM32F107VCT6, the VBT6 variant constrains firmware scalability without performance or peripheral reduction, while the F407VGT6 trades IEEE 1588 precision for raw compute power and memory - making the VCT6 optimal for deterministic, multi-protocol time-critical gateways where hardware timestamping and dual-CAN isolation are mandatory.

FAQ
Does STM32F107VCT6 support IEEE 1588 Precision Time Protocol in hardware?
Yes. The integrated 10/100 Ethernet MAC includes dedicated hardware timestamping logic that captures transmit and receive packet timestamps with sub-microsecond resolution, directly supporting IEEE 1588-2008 PTP boundary clock operation without software overhead or CPU intervention.
What is the maximum achievable CAN bit rate with STM32F107VCT6's CAN controllers?
The dual CAN 2.0B controllers support bit rates up to 1 Mbit/s under standard operating conditions (VDD = 3.3 V, ambient temperature ≤85 °C), verified per ISO 11898-1 with propagation delay compensation enabled and sample point set to 75%.
Can STM32F107VCT6 operate as a USB OTG host without external VBUS detection circuitry?
Yes. Pin PA8 is dedicated to VBUS sensing and supports direct connection to USB VBUS (5 V) with internal voltage divider and comparator; no external components are required for host/device role detection or overvoltage protection.
Is the Ethernet MAC capable of full-duplex 100 Mbit/s operation in RMII mode?
Yes. The RMII interface supports full-duplex 100 Mbit/s operation using a 50 MHz reference clock; timing margins meet IEEE 802.3u specifications with ≤2 ns skew between TX_EN/TXD[1:0] and TX_CLK, validated in ST's reference design AN3190.
