Important notes for use

National “chip” upgrade, a protocol conversion solution with higher performance

CSM fully isolated protocol conversion chip integrates Cortex-M4 core MCU and ZLG self-developed power IC, which supports 4 protocol conversion modes, multiple Baud rate gears, error feedback mechanism and the maximum frame flow of 7500 frames/s. The related performance parameters are at the leading level in the industry, providing users with high-quality CAN interface extension solutions.

Originating from the “chip” upgrade, the volume is reduced by 89%.

National “chip” is strengthened, and its working condition adaptability is stronger.

The fully isolated protocol conversion chip is made by mature SiP technology, and it has been systematically conducted with EMC testing. Combined with the product’s wide temperature adaptation range of -40~85℃, it has stronger adaptability to working conditions and meets the requirements of most industrial field applications.

National “chip” empowerment assists industry upgrade

After over 20 years of technical accumulation, Zhiyuan Electronics has realized technological innovation and provided more stable and reliable CAN interface extension solutions for energy storage, charging piles, heavy machinery, coal mines, industrial automation, rail transit, etc.
