STM32 32-bit ARM Cortex MCUs

The STM32F048x6 microcontrollers incorporate the high-performance ARM Cortex -M0 32-bit RISC core operating at a 48 MHz frequency, high-speed embedded memories (32 Kbyte of Flash memory and 6 Kbyte of SRAM), and an extensive range of enhanced peripherals and I/Os. All devices offer standard communication interfaces (one I²C, two SPIs/one I²S, one HDMI CEC and two USARTs), one USB Full speed device (crystal-less), one 12-bit ADC, four general-purpose 16-bit timers, a 32-bit timer and an advanced-control PWM timer.The STM32F048x6 microcontrollers operate in the -40 to +85 °C and -40 to +105 °C temperature ranges, at a 1.8 V ± 8% power supply. A comprehensive set of power-saving modes allows the design of low-power applications.The STM32F048x6 microcontrollers include devices in three different packages ranging from 36 pins to 48 pins with a die form also available upon request. Depending on the device chosen, different sets of peripherals are included. The description below provides an overview of the complete range of STM32F048x6 peripherals proposed.These features make the STM32F048x6 microcontrollers suitable for a wide range of applications such as application control and user interfaces, hand-held equipment, A/V receivers and digital TV, PC peripherals, gaming and GPS platforms, industrial applications, PLCs, inverters, printers, scanners, alarm systems, video intercoms, and HVACs.
