STM32F101ZE  

The STM32F101xC, STM32F101xD and STM32F101xE access line family incorporates the high-performance ARM^®Cortex^®-M3 32-bit RISC core operating at a 36 MHz frequency, high-speed embedded memories (Flash memory up to 512 Kbytes and SRAM up to 48 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All devices offer one 12-bit ADC, four general-purpose 16-bit timers, as well as standard and advanced communication interfaces: up to two I²Cs, three SPIs and five USARTs.

The STM32F101xx high-density access line family operates in the –40 to +85 °C temperature range, from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power applications.

These features make the STM32F101xx high-density access line microcontroller family suitable for a wide range of applications such as medical and handheld equipment, PC peripherals and gaming, GPS platforms, industrial applications, PLC, printers, scanners alarm systems and video intercom.
