AT32F423 Series Datasheet ARM®-based 32-bit Cortex®-M4 MCU, 64 to 256 KB Flash, sLib, 15 timers, 1 ADC, 18 communication interfaces (CAN and OTGFS)
■Descriptions
●The AT32F423 is based on the high-performance ARM®Cortex®-M4 32-bit RISC core operating at a frequency of up to 150 MHz. The Cortex®-M4 core features a Floating point unit (FPU) single precision supporting all ARM® single-precision data processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) that enhances application security.
●The AT32F423 incorporates high-speed embedded memories (up to 256 KBytes of internal Flash memory, 48 KBytes of SRAM), and a wide range of enhanced GPIO ports and peripherals connected to two APB buses. Any block of the embedded Flash memory can be protected by the “sLib” (security library), functioning as a security area with code-excutable only. In addition, the AT32F423 device includes a high-level memory extension: external memory controller (XMC).
●The AT32F423 offers one 12-bit ADC, two 12-bit DACs, eight general-purpose 16-bit timers plus one general-purpose 32-bit timer, two basic timers and one advanced timer. It also features standard and advanced communication interfaces: up to three I²Cs, three SPIs (multiplexed as I²Ss), eight USARTs, two CANs, an OTGFS, and infrared transmitter.
●The AT32F423 operates in the -40 to +105 °C temperature range, from a 2.4 to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power application.
●The AT32F423 offers devices in different package types. They are fully pin-to-pin, software and functionally compatible throughout the AT32F423 series, except that the configurations of peripherals are not fully identical depending on the package types.
