168 MHz Cortex-M4 with 1 MB Flash in a WLCSP footprint
The STM32F415OGY6TR: The 1 MB Flash and 192K x 8 RAM give enough headroom for a real-time control stack plus a communication protocol layer, while the 90-WLCSP package (4.22x3.97 mm) fits designs where board area is the tightest constraint — think wearable sensor hubs, compact motor drives, or portable instrumentation.
Peripheral set and connectivity options
The 72 I/O lines, combined with DMA and a 12-channel DMA controller, keep the core free for number crunching while peripherals move data in the background.
Data conversion and analog integration
Thirteen 12-bit ADC channels and two 12-bit DAC channels are on-chip, covering most sensor-interface and analog-output needs without an external converter.
The base product number STM32F415 covers a family of density and package variants; this specific WLCSP-90 tape-and-reel code is the ordering number for volume assembly.
