168 MHz Cortex-M4F MCU, 1 MB Flash, 192 KB SRAM, USB OTG HS/FS, 2x CAN, LQFP64
The STM32F405RGT6 is a high-performance microcontroller from ST’s STM32F4 series, built on an Arm Cortex-M4 core with FPU running at up to 168 MHz (210 DMIPS). It integrates 1 MB of Flash, 192 KB of SRAM plus 4 KB backup SRAM, three 12-bit 2.4 MSPS ADCs, two DACs, USB OTG FS/HS, two CAN interfaces and SDIO in an LQFP64 package, operating from 1.8 V to 3.6 V. Typical applications include motor drives, industrial PLCs and inverters, medical equipment, printers, alarm systems and HVAC.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
What does the RGT6 suffix mean?
R indicates 64 pins, G indicates 1024 KB of Flash, T indicates the LQFP package, and 6 indicates the industrial -40 to 85 °C ambient temperature range.
Does the STM32F405RG include Ethernet?
No. Ethernet MAC and the camera interface are on the STM32F407 line; the STM32F405RG offers USB OTG FS/HS, two CAN, SDIO and serial interfaces instead.
