3PEAK Launches Two New TPS32 MCU Product Series for Mass Production


After two years of dedicated effort and craftsmanship, 3PEAK's inaugural launch of its embedded processor products has arrived as scheduled.

The TPS32 mixed-signal microcontroller leverages 3PEAK's excellent capabilities in mixed-signal processing. It is suited for product development in vertical applications and optimizing product design so customers can differentiate their end products. 3PEAK provides complete development ecosystem support, including easy-to-use embedded software packages, hardware and software development tools, and a third-party cooperative ecosystem. This full-range support throughout the design and development cycle helps shorten design time for customer products and ensures a smooth user experience.The TPS32 mixed-signal microcontroller series adheres strictly to industrial quality standards throughout the design process, making it an ideal choice for broad industrial applications.


This major launch introduces two series under the TPS32 mixed-signal microcontroller family's Mainstream Line, totaling 26 products now officially in mass production.
