Hi everyone, I have stm32F303re, LQFP64 package. it possible for me to use external SRAM on it?

Pretty sure there are not enough pins to expose an FMC bus. I'm sure you could walk the pin list in the Data Sheet

Depending on what you're attempting to achieve you might be able to interface to a FIFO RAM or FPGA via some GPIO pins

Hello @Patukes​ ,

I recommend you try with STM32G473 5(LQFP64 package).

This device embed high-speed memories (up to 512 Kbytes of Flash memory, and 128 Kbytes of SRAM), a flexible external memory controller (FSMC) for static memories (for devices with packages of 100 pins and more), a Quad-SPI Flash memory interface, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.
