Development of I2C level shifter using µASIC
This paper presents the design and implementation of an I²C level shifter using the AM1U1420 single-chip solution. The device enables seamless voltage translation between different I²C logic levels, ensuring reliable communication between components operating at varying supply voltages. The AM1U1420 can integrate bidirectional level shifting functionality, reducing the need for external components and simplifying circuit design. We analyze its electrical characteristics, performance metrics, and practical application scenarios.
