The 1 MB on-chip Flash and 192 KB SRAM (192K x 8) leave room for a real-time control loop, communication stack, and data buffering without external memory in many designs. The 32-bit single-core processor with DSP instructions and floating-point unit handles sensor fusion, motor control, or audio processing at the rated speed — the 168 MHz ceiling is the practical limit for deterministic interrupt response and throughput. ## 90-WLCSP package — board-fit constraints for the 4.22 x 3.97 mm footprint Housed in a 90-ball WLCSP (4.22 x 3.97 mm), this part is intended for space-constrained designs where a fine-pitch BGA is acceptable. The 0.50 mm ball pitch demands a controlled-impedance PCB with microvias or via-in-pad for fan-out — a two-layer board will not route all 72 I/O cleanly. ## Active lifecycle — production status and compliance documentation STMicroelectronics lists the STM32F405OGY6TR as Active (current production). Pricing and lead time are confirmed at RFQ against the required quantity. ## Connectivity and analog integration — CAN, USB OTG, dual DAC, 13-channel ADC On-chip peripherals include CANbus, USB OTG, I²C, SPI, UART/USART, and IrDA — enough serial interfaces to connect to a CANopen fieldbus, a USB host/device port, and several sensors or actuators without external bridge chips. The 13-channel 12-bit ADC and dual 12-bit DAC allow direct analog signal acquisition and output. Combined with the PWM timer channels and the DMA controller, the part can run a closed-loop control algorithm with minimal CPU intervention.","metaTitle":"STM32F405OGY6TR STM32F4 MCU, 168MHz, 1MB Flash, 90-WLCSP","metaDescription":"STMicroelectronics STM32F405OGY6TR ARM Cortex-M4 MCU, 168MHz, 1MB Flash, 192KB SRAM, 90-WLCSP.
