Product details

It is built for applications that need a real-time control loop plus a communication stack: motor drives using the dedicated PWM timer, CAN gateways, USB-serial bridges, and industrial sensor hubs. The 80 general-purpose I/O pins in a 100-LQFP package give enough headroom to interface parallel LCDs, external memory buses, or multiple encoder inputs without a CPLD.

The 64 KB SRAM handles two or three moderate-sized DMA buffers alongside the stack and heap — enough for a 320x240 frame buffer at 16-bit colour would exceed it, so plan external SRAM or serial RAM if you need that. The 64K x 8 organisation means the SRAM is byte-addressable, which simplifies peripheral DMA transfers.

No last-time-buy window has been announced, and the part remains available through franchised distribution.

Frequently asked questions

What is the difference between STM32F103VET7 and STM32F103VET6?

The VET7 is the extended-temperature version, suitable for environments where the ambient temperature exceeds 85°C. All other specifications — 72 MHz core, 512 KB Flash, 64 KB SRAM, 100-LQFP package, peripheral set — are identical between the two.

What is the closest pin-compatible alternative to STM32F103VET7TR?

For a drop-in replacement with the same industrial temperature grade, the STM32F103VET7 (non-tape-and-reel suffix) shares the same die and package. No second-source manufacturer produces a direct pin-compatible alternative for this part — the STM32F103 is STMicroelectronics proprietary.
