AT32F421C8T7 – ARM Cortex-M4 Microcontroller

Description

Artari Technologies AT32F421 series of value-added ARM ® Cortex ® -M4 microcontrollers, up to 120MHz CPU operation speed and built-in digital signal processor (DSP), can support up to 64KB flash memory (Flash) and 16KB random access Memory (SRAM), up to 2 USARTs, 2 SPIs (reusable I²S), 2 I²Cs, 1 16-bit advanced timer, 5 16-bit general-purpose timers, and 5-channel DMA control are also integrated on-chip device. At the same time, it also expands a high-speed rail-to-rail input/output analog voltage comparator, a 12-bit 15-channel high-speed ADC with a sampling rate of up to 2M SPS, which can fully meet the requirements of high-speed data acquisition, mixed signal processing and industrial control and motor applications. . Almost all I/O ports can tolerate 5V input signal, and all I/O ports are fast I/O, with a variety of optional functions and support for port remapping, excellent flexibility and ease of use to meet a variety of applications need. The AT32F421 series is equipped with the sLib security library (Security Library) developed by Arteli, which can support password protection of the specified range of program areas. The solution provider burns the core algorithm to this area and provides it to downstream customers for secondary development, which strengthens the product itself. The security, reliability and ease of use of secondary development. AT32F421 can operate in the industrial temperature range of -40~105°C. Main features Efficiency/Performance ARM ® Cortex ® -
