CLCQ82C55AZ is a CMOS programmable peripheral interface circuit that is a general-purpose programmable I/O device that can be compatible with many different microprocessors.It provides 24 programmable I/O pins that can be programmed in groups of 12, and can be used in three main operating modes. It has control word read back function, direct set/reset function, and all I/O ports have 2.5mA drive capability, with strong applicability. In static CMOS circuit design, it can ensure lower operating power consumption. The product can directly pin to pin replace similar international products without the need to change the circuit board or system software, achieving complete compatibility and replacement. Chiplon Microelectronics has developed its own testing plan to ensure that the factory products meet or even exceed the original specifications, supporting industrial grade (0 ℃~70 ℃) working temperatures.
