AT32F4212 (value line) series microcontroller is based on ARM® Cortex®-M4 core at a frequency of up to 120 MHz. It features a data signal processor (DSP), up to 64 KB Flash memory and 16 KB SRAM, 2 x USARTs, 2 x SPIs (multiplexed I²S), 2x I²Cs, 1x 16-bit advanced timer, 5 x 16-bit general-purpose timers and 5-channel DMA controller. The powerful on-chip resources, high integration and cost effectiveness give the device a competitive edge in the marketplace. Besides, 1x high-speed rail to rail input/output analog voltage comparator, 1x 12-bit 2MSPS high-speed ADC, and 2x operational amplifiers are embedded in the AT32F4212 device, greatly satisfying the demands in various areas such as fast data acquisition, mixed signal processing, industrial control and motor applications. The AT32F4212 series also offers fast I/Os, almost 5 V-tolerant, and port remapping support, making it more flexible and convenient for users to develop application solutions.
In addition, AT32F4212 series is equipped with Security Library (sLib) developed by Artery, allowing users to program any part of the internal Flash memory protected by such mechanism. Such sLib is code-executable but non-readable, making it more secure for solution providers to write core algorithm in it, but also easier for them to carry out second-level development. The device operates in the temperature range of -40 to 105 ℃ and at 2.4 to 3.6V supply. It also features three low-power modes (Sleep/Deepsleep/Standby modes) to save power.
