STM32F103CBT6 Overview

The STM32F103CBT6 is a medium-density STM32F1 performance-line microcontroller with a 72 MHz Arm Cortex-M3 core, 128 KB of Flash and 20 KB of SRAM in a 7 x 7 mm LQFP-48 package. It is the 128 KB step-up from the popular STM32F103C8T6 in the same footprint, with USB full-speed, CAN 2.0B, dual 12-bit ADCs and a motor-control timer.

Key Features

  • Arm Cortex-M3 core up to 72 MHz (1.25 DMIPS/MHz)
  • 128 KB Flash and 20 KB SRAM
  • 2.0 V to 3.6 V supply; 37 I/Os in LQFP-48, almost all 5 V tolerant
  • Two 12-bit, 1 µs ADCs and 7-channel DMA
  • USB 2.0 full-speed, CAN 2.0B active, up to 3 USARTs, 2 SPIs (18 Mbit/s), 2 I2C
  • Seven timers including a 16-bit motor-control PWM timer with dead-time generation

Applications

  • Motor drives and application control
  • Medical and handheld equipment
  • PC and gaming peripherals
  • Industrial applications, PLCs and inverters
  • Printers, scanners, alarm systems and HVAC
