With 114 I/O lines brought out to a 144-LQFP package (20x20 mm body, 0.5 mm pitch), this MCU has the pin count to support parallel buses and multiple serial interfaces simultaneously. On-chip peripherals cover brown-out detect, POR, PWM, a watchdog timer, DMA, I²S for audio, and an LCD parallel interface. The data converter section provides 24 analog inputs multiplexed to a 12-bit ADC and two 12-bit DAC channels.
It is ROHS3 compliant.
The STM32F405ZGT6 is rated for a 168 MHz core clock. At this speed the Cortex-M4 with FPU delivers enough throughput for real-time control loops, sensor fusion, and audio processing without an external DSP.
The STM32F405ZGT6 and STM32F407ZGT6 share the same 144-LQFP footprint, 168 MHz Cortex-M4 core, 1 MB Flash, and 192 KB RAM. The STM32F407 adds a hardware cryptographic accelerator and a true random number generator. For designs that do not use those blocks, the STM32F405ZGT6 is a pin-compatible, functionally equivalent drop-in. Verify the peripheral set against your firmware before committing.
