The 256 KB Flash is sufficient for moderate application code, a real-time OS kernel, and communication stacks; the 48 KB SRAM gives room for several packet buffers and a modest heap. If your firmware image is pushing past 200 KB or you need double-precision floating-point, you are looking at the wrong density tier. ## Peripheral set — USB, CAN, and 21-channel ADC The DMA controller can offload peripheral data transfers without stalling the core. ## Package and mounting — 144-LQFP, 20x20 mm body The 144-LQFP package has a 20x20 mm body with a 0.5 mm pin pitch. It is a surface-mount part intended for reflow soldering.","metaTitle":"STM32F103ZCT6TR STM32F1 ARM Cortex-M3 MCU, 72MHz","metaDescription":"STMicroelectronics STM32F103ZCT6TR 32-bit ARM Cortex-M3 MCU, 72MHz core, 256KB Flash, 48KB SRAM, 144-LQFP.
