With 512KB of Flash memory and 64KB of SRAM, it provides ample code and data space for complex embedded applications. The device offers an exceptionally rich peripheral set: three 12-bit ADCs with 1us conversion time and up to 21 channels (with triple sample-and-hold for simultaneous sampling), two 12-bit DACs for analog waveform generation, five USARTs with LIN\/ISO7816\/IrDA support, three SPI interfaces (two with I2S multiplexed), two I2C interfaces, CAN 2.0B active, USB 2.0 full-speed, and an SDIO interface. Two advanced 16-bit PWM timers with dead-time generation and emergency stop are specifically designed for motor control applications. The Flexible Static Memory Controller (FSMC) supports Compact Flash, SRAM, PSRAM, NOR, and NAND memories, enabling external memory expansion for data logging or program execution. A 12-channel DMA controller handles data transfers for ADC, DAC, SPI, I2S, I2C, USART, and SDIO without CPU intervention. The STM32F103ZEH6 is housed in a compact 144-pin BGA package (10x10mm) with 112 I\/O pins, most of which are 5V-tolerant, and operates from -40 to +105C.","working_principle":"The STM32F103ZEH6 operates as a 32-bit embedded microcontroller. Key subsystems include: (1) Cortex-M3 Core - a 32-bit ARMv7-M architecture processor with 3-stage pipeline, nested vectored interrupt controller (NVIC) supporting up to 60 maskable interrupts with 16 priority levels, and Memory Protection Unit (MPU) for privileged software execution; the core delivers 1.25 DMIPS\/MHz at 0-wait-state memory access; (2) Bus Matrix - a multi-AHB bus matrix connects the Cortex-M3 core, DMA controllers, and peripherals through multiple AHB and APB buses, enabling concurrent access to different peripherals without bus contention; (3) Memory Subsystem - 512KB Flash with prefetch buffer and accelerator for zero-wait execution at 72MHz; 64KB SRAM accessible by both CPU and DMA; FSMC provides external memory expansion with 4 chip selects supporting NOR, NAND, SRAM, PSRAM, and Compact Flash; (4) ADC Subsystem - three independent 12-bit ADCs can operate in single, continuous, scan, or discontinuous modes; triple sample-and-hold enables simultaneous sampling of up to 3 channels; DMA transfers convert results to memory buffers; (5) Motor Control Timers - two advanced 16-bit timers (TIM1 and TIM8) feature complementary PWM outputs with programmable dead-time, break input for emergency motor shutdown, and encoder interface for brushless DC motor control.","pin_description":"
