The 80 general-purpose I/O pins in a 100-LQFP package give enough headroom to interface parallel LCDs, external memory buses, or multiple encoder inputs without a CPLD. The 64 KB SRAM handles two or three moderate-sized DMA buffers alongside the stack and heap — enough for a 320x240 frame buffer at 16-bit colour would exceed it, so plan external SRAM or serial RAM if you need that. The 64K x 8 organisation means the SRAM is byte-addressable, which simplifies peripheral DMA transfers. No last-time-buy window has been announced, and the part remains available through franchised distribution.","metaTitle":"STMicroelectronics STM32F103VET7TR ARM Cortex-M3 MCU, 72MHz","metaDescription":"STM32F103VET7TR is a 32-bit ARM Cortex-M3 MCU with 512KB Flash, 64KB SRAM, 72MHz core, CAN/USB/SPI/I2C.
