I/O Expander​

AST1700

The AST1700 is a versatile I/O expander chip designed to complement ASPEED's AST2700 series BMCs. It enhances system capabilities by providing additional I/O expansion options, including 1Gb/s bandwidth LTPI (UART/GPIO/SGPIO/I2C), MCTP over I2C/I3C, PWM, TACH and ADC. It is ideal for high-performance server environments, enabling efficient and flexible I/O configurations.
