The 2021 China IoT Innovation Awards was announced, and APT’s 32-bit MCU APT32F1023 won the best

On December 10, the 2021 China IoT Conference and IoT Innovation Award was grandly held in Shenzhen. APT 32-bit MCU APT32F1023 won the best - 'Golden Lion Product Award' - for its own technology, high-performance and trusty.

The China IoT Innovation Award is the most professional and influential industry award in China's IoT industry, hosted by the Elecfans . It aims to discover and recognize outstanding technologies with innovative value and far-reaching impact in the IoT industry, as well as innovative products which highly concerned and recognized by the market and industry users. After multiple rounds of selection and voting, APT's 32-bit MCU finally won the 'Golden Lion Product Award', which fully demonstrated the industry’s high recognition of APT's products.

The award-winning APT32F1023 is a 32-bit MCU, developed and launched by APT in 2021 based on T-Head chip, and totally made in China. It is China's first mass-produced 32-bit MCU based on 55nm, 12-inch wafer technology. The APT32F1023 has superior performance with all its performance targets reaching the international advanced level. It adopts industrial-grade standard design to have a main frequency of up to 48MHz; it has rich peripheral interfaces to support hardware CRC and independent divider, and support internal module interconnection trigger; it is equipped with enhanced PWM and 12-bit high-precision ADC; and it has excellent performance such as wide voltage and high signal-to-noise ratio.

In the market, APT32F1023 has long been recognized by Midea, Bosch, Xiaomi, Panasonic, Procter & Gamble, Joyoung, OPPO and other brands, and is widely used in industrial control, IoT, CE and other fields. Up to now, with the cumulative shipment exceeding 100 million, APT32F1023 is a non-ARM architecture 32-bit MCU with the largest shipment in China, ranking first in market share.

In the future, based on its own technological advantages and strong IP design capabilities, APT will continue to adhere to independent innovation made in China, developing and mass-producing more made-in-China innovative MCU products, and realizing China’s independence and control in the MCU field!
