On February 28, Artery officially released the AT32L021, the first entry-level low-power MCU, with different capacities of Flash and SRAM, providing 7 package types with a total of 21 models to choose from, with a minimum package area of only 3x3mm. In order to reduce energy consumption and prolong the operation time of the equipment, the AT32L021 series supports a variety of energy consumption modes and sleep modes, provides short start-up time and a variety of wake-up sources, especially suitable for portable devices, wireless sensors, OBD, BMS, RF industrial control, wireless communication modules and Internet of Things devices and other devices that rely on battery power and small space development and design needs.
Excellent power efficiency and battery life
The AT32L021 series uses a 32-bit ARM Cortex-M0+ core with a frequency of 80MHz and supports up to 64KB Flash and 9KB SRAM. AT32L021 has the advantages of fast entry and wake-up low power consumption mode and low standby power consumption, the current in deep sleep mode is about 9UA, the wake-up time is less than 17us, and the current in standby mode is only 12UA and 5 WKUP pins to wake up standby mode to achieve true low-run, low-standby current and high-speed wake-up core advantages to effectively extend battery life.
The AT32L021 series supports a variety of clock sources (CRMs), including HEXT, HICK, LEXT, PLL and LICK oscillator frequencies, each of which can be switched independently for flexible switching. When not in use, it can be turned off to reduce energy consumption, and the working frequency of the dynamic management system can meet the application requirements in different scenarios and reduce the power consumption of the MCU.
Highly integrated peripherals reduce data latency
To reduce the processing time and power consumption of the core, a wide range of peripherals are integrated on-chip, such as a 12-bit high-speed ADC with a sample rate of up to 2 msps, a 16-bit advanced timer, five 16-bit general-purpose timers, and a 16-bit basic timer. In terms of communication, it has 2 I2C, 2 SPI I2S, 4 USART, 1 CAN interface, and 1 infrared emitter, and the 4 USART interfaces can be operated by DMA, and can be configured as TX RX pin interchange, each channel has a special hardware DMA request logic, which can be triggered by hardware for continuous communication, effectively reducing data transmission delay; The CAN interface supports 20b specification, with high reliability and good error detection ability, is widely used in the automotive and industrial fields.
Industrial-grade products enhance reliability
The AT32L021 series has up to 39 fast GPIOs, and the I-O port supports 5V tolerance, which can prevent 5V voltage surge from damaging the port. It supports a wide temperature range of -40 105 industrial grade and provides a certified IEC-60730 safety test library to ensure safe operation of the equipment.
In order to strengthen the confidential security protection of the product, AT32L021 is equipped with the SLib security library (Security Library) developed by Artery, which supports password protection of the designated program ** security library area, so that the solution provider can burn the core algorithm to this area, so that it can only be executed and cannot be read, providing downstream customers with the convenience of secondary development and enhancing the reliability of product development and use.
Artery provides users with a complete development ecosystem system, continuously improves various software and hardware development tool platforms, from the system development stage to mass production programming and subsequent firmware updates, provides hardware support including AT-START development board, AT-Link Family programming and debugging tools, as well as BSP standard library, ICP ISP programming tools, AT32 IDE, AT32 Workbench graphical (GUI) development tools and other software resources. At the same time, it supports third-party development tool platforms such as Keil, IAR, and Eclipse, as well as OS UI platforms such as RT-Thread OS, FreeRTOS, and LittleVGL, providing developer convenience, reducing repetitive setup work, effectively shortening development and mass production time, and speeding up the product launch cycle.
At present, the AT32L021 series products have begun to send samples and will be officially put into mass production and supply in March 2024.
