The STM32F107VBT6 — a connectivity-centric ARM Cortex-M3 MCU
Its headline feature is the integrated Ethernet MAC and dual CAN 2.0B interfaces, which distinguish it from the mainstream STM32F103 line and make it a natural fit for industrial gateways, PLCs, building automation controllers, and protocol converters.
The 72 MHz clock rate on this ARM Cortex-M3 is the same performance tier as the widely used STM32F103, but the STM32F107VBT6 adds Ethernet and dual CAN without dropping the core speed. That means the CPU can handle both the protocol processing (Ethernet frame checksum, CAN message filtering) and the application logic without a separate communication coprocessor.
Ethernet and CAN — the interfaces that define this part
The STM32F107VBT6 includes an Ethernet MAC (Media Access Controller) that supports 10/100 Mbit/s operation with a dedicated DMA controller and a choice of MII or RMII PHY interfaces. On the CAN side, there are two CAN 2.0B active channels with 28 mailboxes each, suitable for dual-bus gateway designs or redundant communication paths. The USB OTG peripheral adds host/device flexibility for firmware updates, data logging, or connection to a touchscreen HMI.
The 80 available I/O pins in the 100-LQFP package give enough GPIO for parallel LCD interfaces, keypad matrices, or multi-sensor arrays while still leaving room for the Ethernet and CAN pins.
Lifecycle status — active, no EOL pressure
There is no last-time-buy date, no NRND flag, and no announced end-of-life. The base product number STM32F107 covers multiple density and package variants, so if a future design needs more Flash or a different pin count, the migration path stays within the same family without a core architecture change.
As an Active, in-production STM32 part, the STM32F107VBT6 is available through the independent distribution channel. For volume requirements or scheduled deliveries, we can also support forward bookings. The ROHS3 compliance is current, so no exemption paperwork is needed for EU or global markets.
