Lingdong Microelectronics launches new MM32F5 series products, all equipped with ARM Technology's "Star" STAR-MC1 processor

On the afternoon of April 12, Shanghai Lingdong Microelectronics Co., Ltd. (hereinafter referred to as "Lingdong Microelectronics") held an online press conference to launch the new MM32F5 series MCU products.

According to Wang Wei, marketing director of Lingdong Microelectronics, the MM32F5 series adopts the Armv8-M Mainline architecture and is equipped with the ARM Technology "Star" STAR-MC1 processor. It has made many innovations in architecture and peripheral design and can adapt to various high-end markets such as industry, IoT, and automobiles.

Wang Wei mentioned that the MM32F5 series uses the ARM Technology "Star" STAR-MC1 processor based on four considerations. The first is high performance. Compared with the M3/M4 series, the performance of the MM32F5 series is improved by 20%; the second is multi-concurrency. The built-in L1 I/D cache and the independent TCM interface can greatly improve the parallelism of storage access; the third is that the Arm ecosystem is complete and supports KEIL, IAR, GCC, J-LINK, ULINK2 and other compilation and debugging tools, which will help Lingdong Microelectronics expand its customer base; the fourth is that the processor is built by a local team to ensure the security of the supply chain.

So what are the product features of the MM32F5 series equipped with ARM's "Star" STAR-MC1 processor? Wang Wei pointed out that this series of products first has a rich communication interface, supports Ethernet, USB and dual FlexCAN interfaces, and has up to 14 groups of UART, SPI and I2C; secondly, it has large-capacity storage, covering 256KB to 2MB, and uses a dual-partition configuration, which is conducive to the reliability and stability of the entire system operation; thirdly, it has improved high-performance analog and timers , using 2 groups of 3MSPS12-bit SAR ADC, supporting 256 times hardware oversampling, and setting 2 groups of advanced timers, supporting 8-channel complementary PWM output; finally, it has added MindSwitch, a peripheral interconnection system created by Lingdong Microelectronics, for the first time, which can support synchronous processing and logical operations between any peripherals and GPIO, so that the system can achieve higher performance.

As for the product layout of the MM32F5 series, it is divided into three sub-series - MM32F52, MM32F53 and MM32F55, with storage capacity covering 256 KB to 2MB and main frequency covering 120MHz to above 200MHz.

At present, Lingdong Microelectronics has taken the lead in launching two products in the MM32F52 series, namely MM32F5270 and MM32F5280. Among them, MM32F5270 can provide up to 256KB of Flash capacity, and MM32F5280 has a maximum Flash capacity of 2MB.

In terms of application scenarios, the above two products have been connected with manufacturers of industrial automation, building automation, and home appliance control, and have received very positive feedback. Taking industrial automation applications as an example, Lingdong Microelectronics has made early arrangements in this market based on its insight into industrial market trends, and previously launched products such as MM32F3270 have also been introduced to leading industrial customers.

In addition, Wang Wei also mentioned that for MCU manufacturers, a complete ecosystem is an unavoidable topic. "While launching the high-performance MCU product - MM32F5 series, Lingdong Microelectronics will also simultaneously release supporting new software and hardware platforms and development tools to provide users with a more comprehensive development and evaluation experience. For example, on the current Plus-F5270 development board, you can see some major interfaces, including Ethernet, USB, SD card slot, LCD display, sensor, etc." Wang Wei mentioned.
