Brief Description

The STM32F103VBI6 is a microcontroller in the product category of electronic components. It features an ARM 32-bit Cortex™-M3 CPU with a clock speed of 72 MHz and provides 90 DMIPS with 1.25 DMIPS/MHz. The microcontroller has a single-cycle multiplication and hardware division capability, along with a nested interrupt controller with 43 maskable interrupt channels. It also offers various memories, including 32-to-128 Kbytes of Flash memory and 6-to-20 Kbytes of SRAM. The clock, reset, and supply management features include a 2.0 to 3.6 V application supply and I/Os, POR, PDR, and programmable voltage detector (PVD), a 4-to-16 MHz quartz oscillator, an internal 8 MHz factory-trimmed RC, internal 32 kHz RC, PLL for CPU clock, and a dedicated 32 kHz oscillator for RTC with calibration. The microcontroller supports low power modes such as Sleep, Stop, and Standby modes, and has a VBAT supply for RTC and backup registers. It also offers 2 x 12-bit, 1 µs A/D converters with a conversion range of 0 to 3.6 V, dual-sample and hold capability, synchronizable with advanced control timer, and a temperature sensor. The STM32F103VBI6 also features a 7-channel DMA controller that supports peripherals such as timers, ADC, SPIs, I2Cs, and USARTs.
