Product details

168 MHz Cortex-M4 with 1 MB Flash — the BOM-fit tier

It belongs to the STM32F4 series, which brings a hardware floating-point unit and DSP instructions to the mid-density MCU tier — the deciding factor when a design needs real-time FFT, motor-control math, or audio processing without an external DSP. The 1 MB Flash (1M x 8) and 192K x 8 RAM give enough headroom for a full RTOS, a TCP/IP stack, and a moderate application image without pushing into the 2 MB density bracket.

Temperature grade and package — 105°C ceiling in a 100-LQFP

The 100-LQFP (14x14 mm body) is a hand-solderable, inspectable package that keeps board-level rework straightforward — no BGA reball station needed.

ROHS3 compliant.

Frequently asked questions

How much flash memory does STM32F405VGT7 have?

That is enough for a full RTOS, a TCP/IP stack, and a substantial application image without pushing into the 2 MB density tier.

Does STM32F405VGT7 have a CAN bus interface?

Yes, the connectivity set includes CANbus.

What is the core processor of STM32F405VGT7?

The core is an ARM Cortex-M4, 32-bit single-core, running at 168 MHz. It includes a single-precision floating-point unit and DSP instructions, which differentiates it from the Cortex-M3 based STM32L1 series.
