Product details

What this STM32F405ZGT7 brings to the board

It packs 1 MB of Flash and 192 KB of SRAM, giving you room for a real-time OS, a TCP/IP stack, and a few hundred kilobytes of data buffers without external memory. The 144-LQFP package (20x20 mm) breaks out 114 I/O, plus interfaces like CAN, USB OTG, EBI/EMI, and multiple SPI/I²C/UART ports — enough to talk to sensors, displays, and fieldbus networks on one chip.

168 MHz and the peripherals that use it

This part includes two 12-bit DACs, 24 12-bit ADC channels, a DMA controller, and a PWM timer set that can drive a three-phase motor or a multi-channel SMPS. The EBI/EMI interface lets you hang an external SRAM or NOR Flash without bit-banging GPIO — useful if your application needs a framebuffer or a large lookup table. The internal oscillator is rated, so you can skip the external crystal for cost-sensitive builds, but the PLL accuracy still benefits from a 25 MHz can for USB or Ethernet.

ST lists the STM32F405ZGT7 as Active, so there is no end-of-life clock ticking on this order code. It is ROHS3 compliant. No LTB risk, no last-time-buy math to run.

Frequently asked questions

Where can I buy STM32F405ZGT7 and get a price?

Submit a request and we will confirm availability and current pricing at quote time — no stock count or price is published here because the market moves daily.

Is STM32F405ZGT7 obsolete or end-of-life?

No, it is listed as Active by STMicroelectronics. There is no announced end-of-life or last-time-buy for this order code.

What is the maximum operating frequency of STM32F405ZGT7?

The core runs at 168 MHz, which is the maximum clock from the PLL with the appropriate flash wait states configured.

Can STM32F405ZGT7 be used as a drop-in replacement for STM32F405ZGT6?

The STM32F405ZGT7 is the same base product and shares the same 144-LQFP package and pinout. Electrically they are identical, so the ZGT7 can replace a ZGT6 in any design, but the reverse may not hold if the application exceeds 85°C.

Is STM32F405ZGT7 pin compatible with STM32F407?

The STM32F405 and STM32F407 share the same pinout in the 144-LQFP package, so the ZGT7 is pin-compatible with the STM32F407ZG variants. The F407 adds a hardware FPU and a few extra peripherals like Ethernet MAC, but the footprint and supply rails are the same.
