¡El GD32F150xx device belongs to the value line of GD32 MCU family. It is a 32-bit general-purpose microcontroller based on the high performance ARM® Cortex® -M3 RISC core with best ratio in terms of processing power, reduced power consumption and peripheral set. ¡El Cortex® -M3 is a next generation processor core which is tightly coupled with a Nested Vectored Interrupt Controller (NVIC), SysTick timer and advanced debug support. ¡El GD32F150xx device incorporates the ARM® Cortex® -M3 32-bit processor core operating at 72 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It provides up to 64 KB on-chip Flash memory and up to 8 KB SRAM memory. An extensive range of enhanced I/Os and peripherals connected to two APB buses. ¡El devices offer one 12-bit ADC, one 12-bit DAC and two comparators, up to five general-purpose 16-bit timers, a general-purpose 32-bit timer, a basic timer, a PWM advanced-control timer, as well as standard and advanced communication interfaces: up to two SPIs, two I 2 Cs, two USARTs, a I 2 S, a HDMI-CEC a TSI and an USB 2.0 FS. ¡El device operates from a 2.6 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. ¡El above features make the GD32F150xx devices suitable for a wide range of applications, especially in areas such as industrial control, motor drives, user interface, power monitor and alarm systems, consumer and handheld equipment, gaming and GPS, E-bike and so on.
