Xihua Technology launches the first capacitive touch 32-bit automotive-grade MCU

Recently, Xihua Technology announced that its automotive-grade capacitive touch CVM012x series MCU is officially on the market.

CVM012x Series Development Board

As the first domestically produced true automotive-grade single-chip solution that can realize HoD applications, this series of products inherits the Xihua CVM01 platform that has been mass-produced, integrating the ARM Cortex-M0+ core, large-capacity Flash memory, SRAM memory and rich peripheral resources.

At the same time, the CVM012x series of automotive MCUs integrates high-performance capacitance detection IP, adopts Xihua's original patented capacitance detection technology, has extremely high capacitance detection accuracy, self-interconnected capacitance detection technology, supports up to 2nF load capacitance, 30ch self-capacitance channel and 15 x 15ch mutual capacitance channel, and supports Active Shielding technology to better support touch waterproof performance. The CVM012x series supports multiple packages and multiple Flash configurations, and has a rich product matrix to meet the actual needs of customers' products. The product meets the reliability AEC-Q100 Grade 2 and can support automotive applications of ISO 26262 ASIL-B functional safety standards.
