兆易创新GD32E103RBT6-GD32 ARM Cortex-M4 Microcontroller

兆易创新GD32E103RBT6-GD32 ARM Cortex-M4 Microcontroller GigaDevice Semiconductor Inc. GD32E103xx ARM® Cortex™-M4 32-bit MCU Datasheet General description The GD32E103xx device belongs to the connectivity line of GD32 MCU Family. It is a 32-bit general-purpose microcontroller based on the ARM® Cortex™-M4 RISC core with best cost- performance ratio in terms of enhanced processing capacity, reduced power consumption and peripheral set. The Cortex™-M4 core features implements a full set of DSP instructions to address digital signal control markets that demand an efficient, easy-to-use blend of control and signal processing capabilities. It also provides powerful trace technology for enhanced application security and advanced debug support. The GD32E103xx device incorporates the ARM® Cortex®-M4 32-bit processor core operating at 120 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It provides up to 128 KB on-chip Flash memory and 32 KB SRAM memory. An extensive range of enhanced I/Os and peripherals connected to two APB buses. The devices offer up to two 12-bit 3 MSPS ADCs, two 12-bit DACs, up to ten general 16-bit timers, two 16-bit PWM advanced timers, and two 16-bit basic timers, as well as standard and advanced communication interfaces: up to three SPIs, two I2Cs, three USARTs and two UARTs, two I2Ss, an USBFS and two CANs. The device operates from 1.71 to 3.6 V power supply and available in –40 to +85 °C temperature range. Several power saving modes provide the flexibility for maximum optimization between wakeup latency and power consumption, an especially important consideration in low power applications. The above features make GD32E103xx devices suitable for a wide range of interconnection and advanced applications, especially in areas such as industrial control, motor drives, consumer and handheld equipment, human machine interface, security and alarm systems, POS, automotive navigation, IoT and so on.
