Ultra-high performance — AT32F437 series, powered by ARM® Cortex®-M4 core, has brought about up to 288 MHz computing speed to the world. Featuring internal single precision floating-point unit (FPU), digital signal processor (DSP) and memory protection unit (MPU), it is provided with rich peripherals and flexible clock control mechanism for a wide range of applications. In particularly, it supports up to 4032 KB Flash memory and 512 KB SRAM, far beyond its counterparts in terms of performance.
Besides, AT32F437 series is also provided with Security Library. This library is a defined area protected by a code in the main memory so that solution providers can not only program core algorithm in it with great peace of mind, but also provide downstream customers with room for secondary development. Meanwhile, AT32F437 series incorporates 2x OTG controllers (Xtal-less in device mode), 2x QSPIs for external SPI Flash memory or SPI RAM extension, 8x UARTs, 2x CANs, 4x SPIs/I²Ss (2x full-duplex), 3x high-speed ADC engines (5.33 Msps), 8~14 bit digital video parallel interface (DVP), an XMC for the extension of SDRAM, SRAM and PSRAM, and IEEE-802.3 10/100Mbps Ethernet port controller for IoT applications, greatly improving the reliability while lowering the costs. AT32F437 devices can perform well in the temperature range of -40 to 105 ℃ . It also provide a variety of chips for selection in response to diverse memory requirements through its powerful on-chip resource allocation, higher integration and cost-effectiveness. Thanks to its outstanding performance, the AT32F437 series will be undoubtedly the best partner for applications that require higher computation and larger memory including industrial automation, motor control, IoT and consumer electronics.
