STM32F407VGT6 vs STM32F407ZGT6: MCU Package and Memory Comparison

ElecSuppliers Part Number ComparisonAug 16, 2026

STM32F407VGT6 and STM32F407ZGT6 are both 32-bit microcontrollers from the STM32F4 family. They share the same STM32F407 MCU platform and are based on the ARM Cortex-M4 core, making them suitable for embedded control, industrial automation, motor control, communication equipment, and other applications that require higher processing performance.

The main differences between STM32F407VGT6 and STM32F407ZGT6 are related to the package, number of available I/O pins, and package-specific pin configuration. Their core architecture and memory capacity are closely related, so the package selection becomes an important consideration when choosing between these two part numbers.

STM32F407VGT6 vs STM32F407ZGT6

Both STM32F407VGT6 and STM32F407ZGT6 belong to the STM32F407 family and use the Cortex-M4 architecture.

The key specifications to consider include:

CPU core

Operating frequency

Flash memory

SRAM

Package

Number of I/O pins

Peripheral interfaces

ADC resources

Timers

Communication interfaces

For many embedded applications, the processing and memory capabilities of the two devices are similar. The more visible difference is the package and resulting I/O availability.

STM32F407VGT6 Package

STM32F407VGT6 uses the LQFP100 package.

The 100-pin package provides a substantial number of GPIO and peripheral connections while keeping the overall PCB footprint relatively manageable.

It is commonly considered for embedded systems where the application requires multiple interfaces but does not need the higher pin count provided by larger STM32F4 packages.

Typical applications include:

Industrial controllers

Embedded control boards

Motor control systems

Communication equipment

Data acquisition equipment

Human-machine interfaces

STM32F407ZGT6 Package

STM32F407ZGT6 uses the LQFP144 package.

Compared with the 100-pin package used by STM32F407VGT6, the 144-pin package provides more physical pins for GPIO and peripheral functions.

This can be useful when an application requires a larger number of external connections.

For example, a complex control board may need multiple communication interfaces, additional ADC channels, external memory connections, displays, sensors, or other peripherals.

In such cases, the additional pins available on the STM32F407ZGT6 can provide more flexibility during PCB design.

Memory Comparison

STM32F407VGT6 and STM32F407ZGT6 are both commonly specified with:

1 MB Flash memory

192 KB SRAM

This means that changing from STM32F407VGT6 to STM32F407ZGT6 does not necessarily provide a larger Flash or SRAM capacity.

The main reason to choose the 144-pin device is generally the additional I/O and package flexibility rather than increased program memory.

For an existing application, engineers should therefore determine whether the limitation is memory capacity or available physical I/O before selecting the device.

ARM Cortex-M4 Performance

Both devices are based on the ARM Cortex-M4 architecture with floating-point support and DSP-oriented processing capabilities.

The STM32F407 family can operate at frequencies up to 168 MHz, providing substantially higher processing performance than many earlier STM32 microcontroller families.

This makes the STM32F407 platform suitable for applications involving:

Real-time control

Digital signal processing

Motor control

Industrial automation

Audio processing

Communication

Embedded graphics

Sensor data processing

The common MCU architecture means that software developed for one STM32F407 package variant can often provide a useful starting point for another variant, although hardware-specific pin assignments must still be reviewed.

STM32F407VGT6 vs STM32F407ZGT6 I/O

The difference in package size directly affects the number of available pins.

STM32F407VGT6 uses a 100-pin package, while STM32F407ZGT6 uses a 144-pin package.

This difference can become important when the application has a large number of external signals.

A design using STM32F407VGT6 may need to carefully allocate GPIO and alternate-function pins.

The STM32F407ZGT6 provides additional physical pins, which can make complex PCB designs easier to accommodate.

However, additional package pins do not mean every peripheral becomes independently available. Alternate-function assignments, shared peripheral pins, power connections, and device-specific pin mapping must still be checked.

Peripheral Features

The STM32F407 family integrates a broad range of peripherals.

Depending on the specific device configuration, these include:

UART and USART

SPI

I2C

CAN

USB

SDIO

Ethernet

ADC

DAC

Timers

GPIO

DMA

The combination of high processing performance and integrated peripherals allows STM32F407 devices to be used in systems that previously required multiple external controllers.

When comparing STM32F407VGT6 and STM32F407ZGT6, engineers should examine the exact pin mapping for the peripheral functions required by their application.

Can STM32F407VGT6 Replace STM32F407ZGT6?

Whether STM32F407VGT6 can replace STM32F407ZGT6 depends mainly on the hardware requirements of the existing design.

If the existing STM32F407ZGT6 design uses only a limited number of GPIOs and does not depend on pins available only through the larger package, moving to STM32F407VGT6 may be possible after a detailed pin and PCB review.

However, if the existing design requires more than the available pins on the 100-pin package, STM32F407VGT6 may not be suitable without hardware redesign.

The same principle applies in the opposite direction. Moving from STM32F407VGT6 to STM32F407ZGT6 can provide additional pin availability, but it does not automatically make the two devices drop-in compatible.

PCB Design Considerations

Package differences are particularly important for existing PCB designs.

STM32F407VGT6 uses LQFP100, while STM32F407ZGT6 uses LQFP144. These packages have different physical dimensions, pin counts, and PCB footprints.

Therefore, switching between the two devices normally requires PCB layout verification and potentially a board redesign.

Engineers should check:

Package dimensions

PCB footprint

Pin numbering

Power pins

Ground pins

GPIO assignments

Peripheral alternate functions

Clock connections

Reset circuitry

Debug interface

External memory connections

Before production, the complete schematic and PCB should be reviewed using the exact device documentation.

Which STM32F407 Should You Choose?

STM32F407VGT6 can be a practical choice when the design requires the STM32F407 processing platform but does not need a very high number of physical I/O connections.

STM32F407ZGT6 is more appropriate when the design requires the additional pins provided by the 144-pin package.

The choice should therefore be based on the actual hardware architecture rather than simply selecting the device with the larger package.

For a new design, engineers can select the package based on GPIO, peripheral, PCB size, and future expansion requirements.

For an existing design, package and pin compatibility should be checked first.

STM32F407VGT6 vs STM32F407ZGT6: Key Difference

The most important distinction between STM32F407VGT6 and STM32F407ZGT6 is the package and associated pin availability.

STM32F407VGT6 uses LQFP100, while STM32F407ZGT6 uses LQFP144.

Both belong to the STM32F407 family and provide the same general Cortex-M4-based MCU platform with substantial Flash, SRAM, processing performance, and peripheral integration.

For engineers comparing these two part numbers, the key question is not simply which MCU is faster. Instead, it is whether the selected package provides enough physical I/O and peripheral connections for the target PCB.

Before selecting or replacing either device, verify the exact datasheet specifications, pin assignment, electrical characteristics, and package requirements for the intended application.
