An internal oscillator is available, though a crystal is still recommended for USB clock accuracy. ## Data conversion and power management Ten 12-bit ADC channels cover analog inputs like thermistors or current-sense resistors. Brown-out detect, POR, and a programmable watchdog are on-chip, so an external supervisor is optional for most designs. ## Lifecycle and supply-chain fit ST lists the STM32F401CDU6TR as Active (current production). For dual-sourcing resilience, the pin-compatible STM32F401CCU6 (same Flash/SRAM, same package) shares the same footprint and peripheral map — a straightforward second-source candidate if supply risk is a concern.","metaTitle":"STM32F401CDU6TR STM32F4 ARM Cortex-M4 MCU, 84MHz","metaDescription":"STM32F401CDU6TR 32-bit ARM Cortex-M4 MCU at 84 MHz with 384 KB Flash, 96 KB SRAM, 36 I/O, USB OTG. -40°C to 85°C, 48-UFQFPN.
