The TMCU series is the first domestically produced automotive-grade MCU capable of supporting capacitive touch loads exceeding 4nF. With the CVA proprietary patented capacitance detection technology, TMCU offers extremely high capacitance detection accuracy. Manufactured with a 40nm domestic process, it achieves an ASIL-B level of functional safety.
Features:
CPU operating frequency up to 80MHz
Maximum 224KB of program flash (PFlash)
32KB of data flash (DFlash)
Up to 16KB of data storage (SRAM)
30 channels of self-capacitance, 15x15 channels of mutual capacitance
Capable of detecting load capacitance up to 4nF
Application Fields: Widely applicable to all automotive controllers requiring touch functionality, including but not limited to steering wheel hand-off detection controllers, air conditioning touch panels, auxiliary dashboard touch panels, interior reading lights, door touch handles, and foot-kick tailgate applications.
Advanced: This project innovatively integrates Touch IC and MCU into a single chip, providing car manufacturers with a single-chip solution for touch applications. This not only facilitates developing car manufacturer solutions but also simplifies material management and ensures the security of the domestic automotive-grade chip supply chain.
Mass Production Capability: Automotive chips have extremely high requirements for product safety and reliability, and the corresponding product development and verification often take 2 to 3 years. This project was initiated in July 2022, and has already achieved chip tape-out verification and small-scale sampling tests. It is expected to achieve mass production and shipment of chips by the end of 2024.
Comparison with Competitors:
The TMCU series innovatively integrates Touch IC and MCU into a single chip, providing car manufacturers with a single-chip solution for touch applications, which simplifies material management and offers superior performance and cost-effectiveness. It supports load capacitance detection up to 4nF, setting a new industry standard. Compared to similar brand chips, it delivers better performance at a lower cost.
