STM32F405RGT6TR is an STMicroelectronics Arm Cortex-M4F microcontroller with 1 MB Flash, 168 MHz, in LQFP-64 tape and reel — for DSP-capable control in a compact 64-pin package: drones, portable instruments and compact motor drives. The 64-pin LQFP is the selection point: F405 performance where the 100-pin VGT package will not fit. Selection advice: the RG denotes 1 MB Flash in LQFP-64 — pin-compatible within the F405 64-pin family. For designs needing Ethernet or camera interfaces, step up to the F407/F429 in larger packages. ST lists this order code as active; we verify availability per lot. Parameters verified against the ST official product page.
Ordering-code highlights reviewed against official manufacturer documentation.
STM32F405RG is available in the following manufacturer order codes. They share the same STM32F405RG design; the table highlights package, packing and ordering differences. Quote the exact code your BOM needs.
| Order code | Package | Packing | Key difference |
|---|---|---|---|
| STM32F405RGT6 | LQFP-64 | — | — |
| STM32F405RGT6TR | LQFP 64 10x10x1.4 mm | — | Compared with STM32F405RGT6, package and listed temperature grade match, but the order-code suffix differs. Verify the factory packing and PCB footprint before treating order codes as interchangeable. |
| STM32F405RGT7 | LQFP 64 10x10x1.4 mm | — | Compared with STM32F405RGT6, temperature grade changes from -40.0 to 85.0 °C to -40.0 to 105.0 °C. Verify the factory packing and PCB footprint before treating order codes as interchangeable. |
| STM32F405RGT7TR | LQFP 64 10x10x1.4 mm | — | Compared with STM32F405RGT6, temperature grade changes from -40.0 to 85.0 °C to -40.0 to 105.0 °C. Verify the factory packing and PCB footprint before treating order codes as interchangeable. |

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
These are order-code variants of the same STMicroelectronics series. They share the core design; the ordering code selects the exact configuration — STM32F405RGT6 (LQFP-64); STM32F405RGT7: Compared with STM32F405RGT6, temperature grade changes from -40.0 to 85.0 °C to -40.0 to 105.0 °C. Verify the factory packing and PCB footprint before treating order codes as interchangeable.; STM32F405RGT7TR: Compared with STM32F405RGT6, temperature grade changes from -40.0 to 85.0 °C to -40.0 to 105.0 °C. Verify the factory packing and PCB footprint before treating order codes as interchangeable.. STM32F405RGT6TR itself is the LQFP 64 10x10x1.4 mm configuration. A code that differs by even one character may be a different device, so always quote the complete code exactly as it appears on your BOM.
From the verified technical profile: Core: Arm Cortex-M4; Flash memory: 1 MB; CPU frequency: 168 MHz. These are the catalog-recorded values for STM32F405RGT6TR — always re-check them against the manufacturer datasheet revision quoted on your BOM before finalizing the design.
