CTOnews.com August 4 news, recently, four-dimensional map of the new Jiefa technology localization supply chain MCU chip AC7802x announced mass production, the chip has been delivered to "a number of benchmarking customers" and large-scale application.

According to reports, the AC7802x series is the second generation of cost-effective MCU chips designed by Jefa Technology based on ARM Cortex-M0 + kernel. The chip has the characteristics of "high reliability, low power consumption and small package", complies with AEC-Q100 Grade 1 certification, can support up to-40 ℃ 125 ℃ at ambient temperature, and can be packaged in TSSOP20 / HVQFN32.

AC7802x platform and AC7801x are compatible with hardware design and software interface, which is convenient for resource expansion and platform selection. In the era of centralization of automotive electronic and electrical architecture, AC7802x is mainly used in automobile terminal node execution layer, such as automotive electronic sensors, temperature control, switches, lights and other MCU application scenarios.

CTOnews.com query found that at present, Jefa Technology has had four generations of iterative mass production of vehicle specification-level MCU chips, from the AC780x series and AC781x series based on M0 + and M3 cores mainly playing the role of small node execution layer, to the AC7840x series based on M4F core as an intermediate force, to the future multi-core domain controller MCU with high computing power and large Pin feet, basically forming a full coverage of the automotive MCU field.

Jiefa Technology said that since the first domestic MCU was produced in 2018, by the end of 2022, the cumulative shipment has exceeded 30 million, covering domestic and foreign mainstream vehicle factories and first-class suppliers, such as Great Wall, Wuling, SAIC, Guangzhou Automobile, Changan, as well as new energy vehicle brands BYD, Ulai, Xiaopeng, ideal and so on.
