10 / 118 page Description STM32F103xC, STM32F103xD, STM32F103xE 10/118 2.2 Full compatibility throughout the family The STM32F103xx is a complete family whose members are fully pin-to-pin, software and feature compatible. In the reference manual, the STM32F103x6, STM32F103x8 and STM32F103xB are referred to as Medium-density devices, while the STM32F103xC, STM32F103xD and STM32F103xE are referred to as High-density devices. High-density devices are an extension of the Medium-density STM32F103x6/8/B/C devices specified in the STM32F103xx datasheet. High-density STM32F103xx devices feature higher Flash memory and RAM capacities, and additional peripherals like SDIO, FSMC, I2S and DAC, while remaining fully compatible with the other members of the family. The STM32F103xC, STM32F103xD and STM32F103xE are a drop-in replacement for the STM32F103x6/8/A/B/C devices, allowing the user to try different memory densities and providing a greater degree of freedom during the development cycle. 2.3 Overview ARM® CortexTM-M3 core with embedded Flash and SRAM The ARM Cortex™-M3 processor is the latest generation of ARM processors for embedded systems. It has been developed to provide a low-cost platform that meets the needs of MCU implementation, with a reduced pin count and low-power consumption, while delivering outstanding computational performance and an advanced system response to interrupts. The ARM Cortex™-M3 32-bit RISC processor features exceptional code-efficiency, delivering the high-performance expected from an ARM core in the memory size usually associated with 8- and 16-bit devices. With its embedded ARM core, STM32F103xC, STM32F103xD and STM32F103xE performance line family is compatible with all ARM tools and software. Figure 1 shows the general block diagram of the device family. Table 3.
