AT32F011 series is based on ARM® Cortex®-M0+ 32-bit core operating at a frequency of up to 80 MHz. This device features 64 KB Flash memory and 8+1 KB SRAM (with parity check). It also embeds a 4 KB system memory that comes with two functions: one that serves as a Bootloader, and another one that is one-time configurable as user instruction and data memory for achieving a maximum of 64+4 KB. AT32F011 offers 4x USARTs (with RS-485 mode), 2x SPIs/I²Ss, 2x I²Cs, 1x 16-bit advanced timer, 5x 16-bit general-purpose timers and 1x 16-bit basic timer. One of its highlights is a 12-bit high-speed 2 Msps ADC that is particularly suited for fast data acquisition, industrial control and motor applications. Furthermore, the device has the ability to enter/leave low-power mode at faster speed. Its ultra-low power consumption is also amazing - around 9uA current consumption and 17us wakeup time in Deepsleep mode, and even 1.2uA current in Standby mode, which could ensure longer battery life and thus makes it the perfect choice for entry-level Value line MCU applications.

The AT32F011 device operates in the temperature range of -40 ℃ to 105℃. It provides a variety of package types from larger to smaller ones to meet different memory demands. With powerful on-chip resources, higher integration and cost-effectiveness, the AT32F011 series is suitable for applications such as IoT, wireless communication, motor control, consumer electronics and BMS.
