Hello everyone, I am Pi Zi Heng, a serious tech enthusiast. Today, I will introduce to you the high-frequency products of domestic Cortex-M core MCU manufacturers.
Yesterday, I released the “2023 Edition of Domestic Cortex-M Core MCU Manufacturers High-Frequency Products,” where I found 12 models with a frequency of no less than 144MHz, which has attracted wide attention. However, some friends commented that there are still two ultra-high frequency models that were not included in the statistics; they are undoubtedly the champions. Therefore, I specifically researched the information, and to my surprise, both of them were released before 2020 and have directly stepped up their operating frequency. I have been focusing on general MCU manufacturers’ products and overlooked these two MCUs that target niche areas. This article will specifically include them:
1. Guoxin Technology CCM4208S@400MHz, can overclock to 500MHz
The CCM4208S security chip is a versatile microcontroller (MCU) based on the Cortex-M4F central processing unit (CPU), featuring low power consumption, high performance, multifunctionality, and high security. It has a built-in hardware acceleration engine for QR code and facial recognition, making it widely applicable in scenarios such as QR codes, fingerprint recognition, facial recognition, smart home, and security video surveillance. Typical operating frequency is 400MHz.

2. Xinzhilian XR872@384MHz
The XR872 chip is a highly integrated single-processor featuring an ARM Cortex-M4F MCU, a low-power 802.11b/g/n WLAN subsystem, an audio codec with ADC and DAC, an image encoder, and a power management unit (PMU). It is designed specifically for smart devices in the Internet of Things and lightweight artificial intelligence product categories.
