Product Description
Low Power, Cortex-M0+ 80MHz CPU, 16~64KB Flash, 9KB SRAM, CAN, ADC, 4USART, DMA Microcontroller®
AT32L021 Series
AT32L021 (L: Low Power) series is based on ARM® Cortex®-M0+ 32-bit core operating at a frequency of up to 80 MHz. This device features 64 KB Flash memory and 8+1 KB SRAM (with parity check). It also embeds a 4 KB system memory that comes with two functions: one that serves as a Bootloader, and another one that is one-time configurable as user instruction and data memory for achieving a maximum of 64+4 KB. AT32L021 offers 1x CAN, 4x USARTs (with RS-485 mode), 2x SPIs/I²Ss, 2x I²Cs, 1x 16-bit advanced timer, 5x 16-bit general-purpose timers and 1x 16-bit basic timer. One of its highlights is a 12-bit high-speed 2 Msps ADC that is particularly suited for fast data acquisition, industrial control and motor applications. Furthermore, the device has the ability to enter/leave low-power mode at faster speed. Its ultra-low power consumption is also amazing - around 9uA current consumption and 17us wakeup time in Deepsleep mode, and even 1.2uA current in Standby mode, which could ensure longer battery life and thus makes it the perfect choice for entry-level low-power MCU applications.
The AT32L021 device operates in the temperature range of -40 ºC to 105ºC. It provides a variety of package types from larger to smaller ones to meet different memory demands. With powerful on-chip resources, higher integration and cost-effectiveness, the AT32L021 series is suitable for applications that require low-power consumption such as IoT, wireless communication, motor control and consumer electronics.

Packing & Delivery
Packing:
Machine packing inside is plastic films and outside is fumigation wooden case.
Our wooden case is very strong,it can bear long time shipping on the sea.
And machine with preservative film, it can stop the salt sea water enter into the machine and make the machine corrosion.
Delivery:
For machines are big and heavy parcel, and different country with different delivery cost,so we suggest below delivery solution:
1. Over 1CBM or 100KG, we suggest send by Sea.
2. Below 1CBM or 100KG, we suggest send by Air.
3. Below 0.5CBM or 50KG, we suggest send by Express.
The price show on our website just the machine EXW price, please contact us for confirm delivery cost before you place order.
