The AK93C41A/51A has 4 instructions such as READ, WRITE, EWEN and EWDS. Those instructions control the AK93C41A/51A. The AK93C41A/51A can operate full function under wide operating voltage range from 0.9V to 3.6V. The charge up circuit is integrated for high voltage generation that is used for write operation. A serial interface of AK93C41A/51A, consisting of chip select (CS), serial clock (SK), data-in (DI) and dataout (DO), can easily be controlled by popular microcontrollers or standard microprocessors. AK93C41A/51A takes in the write data from data input pin (DI) to a register synchronous...
