STM Cortex-M3 MCU ۱۲۸KB FLASH ۲۰KB RAM LQFP64
STM32f103RBT6
Product Overview
The STM32F103RBT6 medium density performance microcontroller incorporates the high performance ARM Cortex™-M3 32 bit RISC core operating at a 72MHz frequency, high speed embedded memories (Flash memory up to 128 Kbytes and SRAM up to 20 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. This device offer two 12 bit ADCs, three general purpose 16 bit timers plus one PWM timer, as well as standard and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs, an USB and a CAN.
