You've explained your application requirements exceedingly poorly. Very few here are interested in doing your due diligence work.

Specifications:

UARTs - 4

SPI - 2

I2C - 2

CAN

Ethernet

SD Card

ADC - 8 - 12bit

NAND Flash

SRAM

Operating Frequency: 120MHz to 400MHz

We are expecting system in such a way that the User can build their application program using ladder logic or any other standard PLC programming languages.

Our system should operate based on user applications

Please share us which of the MCU /MPU is best suitable for our application.

Hi @VKaki ,

First recommendation is to use the MCU finder (from ST web site, as embedded on STM32CubeMX tool or as standalone tool) to look for MCUs that meet your requirement.

Please note that ST supplies some PLC solutions. You can refer to this page on ST web site for more details.
