Product details

Obsolete — plan the last-time-buy or migrate now

Buyers with an active BOM line should secure remaining inventory through independent distribution or evaluate a pin-compatible replacement within the STM32F4 family.

The 1 MB Flash is organized as 1M x 8 bits, suitable for complex firmware stacks including a real-time OS, communication protocol stacks, and application code. The 192 KB SRAM (192K x 8) provides room for large data buffers, double-buffered display frames, or DSP coefficient tables without external memory.

Analog and connectivity integration

The LCD parallel interface supports direct drive of small TFT panels. These peripherals reduce total component count in applications like industrial PLCs, human-machine interfaces, and embedded gateways.

Frequently asked questions

What is the replacement for STM32F405ZGT6J?

STMicroelectronics has not published a single direct successor for the STM32F405ZGT6J. Within the STM32F4 family, the STM32F407ZGT6 is a common pin-compatible alternative that adds a hardware FPU and additional peripherals while maintaining the same 144-LQFP footprint, 1 MB Flash, and 192 KB SRAM configuration. Verify the peripheral set matches your application before substituting.

Does STM32F405ZGT6J come in a tray?

The STM32F405ZGT6J is listed with a Tray shipping medium. The device package is a 144-LQFP (20x20 mm), surface-mount. Tray packaging is typical for LQFP devices in engineering samples and low-to-medium volume production.

What is the difference between STM32F405ZGT6J and STM32F407ZGT6?

Both are 168 MHz ARM Cortex-M4 MCUs in the same 144-LQFP package with 1 MB Flash and 192 KB SRAM. The STM32F407ZGT6 adds a hardware cryptographic accelerator, a true random number generator, and an additional 12-bit DAC channel. The STM32F405ZGT6J omits these crypto/TRNG blocks but is otherwise pin-compatible. If your application does not require hardware encryption, the F405 is functionally equivalent.
