The CW308-STM32F-SOCKET board is the perfect target for testing fault injection against TQFP-64 STM32F/STM32L microcontrollers. Thanks to pin compatablity (mostly) between various devices, this single board supports multiple STM32F/STM32L microcontrollers.
These boards do not ship with any microcontroller, but use a 64-pin TQFP socket.

The STM32F board supports several STM32F devices in the TQFP-64 package. The switch needs to be set in either the "A" or "B" position to select appropriate VCC supply for the different series. The following table summarizes examples of suitable devices, in the following list these devices are available in fixed boards as well.
|STM32F Series||Package||Device||Hardware AES||Tested||Jumper||Flash||SRAM||NAE P/N for Fixed PCB|
|L4||TQFP-64||STM32L443RCT6||Yes||Yes||B||256KB||64KB||NAE-CW308T-STM32L4 (this version has hardware crypto)|
Several devices (F2, F4) have internal core voltage regulators. By default the CW308 board attempts to provide power for these pins, but the voltage may not be high enough to cause the internal regulator to disable itself. In this case you can use the VADJ regulator to ensure the internal regulator is disabled.
Pin-outs across TQFP Devices¶
The following shows differences in pinouts between three groups of devices. The left-most is the STM32F051RB, which uses the same 3.3V VCORE as the STM32F1/F3. It has fewer VCC pins, so the I/O occupying that are VCC/GND pins on the STM32F1 (such as PF6/PF7) are tied to GND/VCC. The right-most part is the pinout of the STM32F2/F4. It has an internal regulator, where the VCAP pins are the output of this regulator (and input to the internal core logic).
Decoupling capacitors C5/C6/C7/C8 are DNM, as they will weaken leakage on devices with a 3.3V core.
Example Projects and Using Target¶
See note above about setting switch SW1 to route correct power to the target device.
