The STM32F401VCH7: 81 I/O lines, 16-channel 12-bit ADC, and connectivity including I²C, SPI, UART/USART, USB OTG, and SDIO.
100-UFBGA package (7x7 mm). Fine-pitch BGA requires controlled reflow and a stencil matching the ball diameter.
That means no last-time-buy deadline looming, no PCN-driven scramble for a replacement.
Buyers need to estimate cost and delivery for their production schedule.
Lifecycle status determines long-term availability and risk of redesign.
Design engineers need full electrical and physical details to validate fit.
Immediate availability is critical for prototyping and production stops.
Sourcing buyers and brokers need drop-in alternatives for supply chain continuity.
Engineers evaluate memory and package differences to select the best variant.
