The AK93C45A/55A/65A/75A has 4 instructions such as READ, WRITE, EWEN and EWDS. Those instructions control the AK93C45A/55A/65A/75A. The AK93C45A/55A/65A/75A can operate full function under wide operating voltage range from 1.8V to 5.5V. The charge up circuit is integrated for high voltage generation that is used for write operation. A serial interface of AK93C45A/55A/65A/75A, consisting of chip select CS , serial clock SK , datain DI and data-out DO , can easily be controlled by popular microcontrollers or standard microprocessors. AK93C45A/55A/65A/75A takes in the write data from data input pin DI to a register synchronously with rising edge of input pulse of serial clock pin SK . And at read operation, AK93C45A/55A/65A/75A takes out the read data from a register to data output pin DO synchronously with rising edge of SK. The DO pin is usually in high impedance state. The DO pin outputs "L" or "H" in case of data output or Busy/Ready signal output. x Software controlled write protection When VCC is applied to the part, the part automatically powers up in the ERASE/WRITE Disable state. In the ERASE/WRITE disable state, execution of WRITE instruction is disabled. Before WRITE instruction is executed, EWEN instruction must be executed. The ERASE/WRITE enable state continues until EWDS instruction is executed or VCC is removed from the part. Execution of a read instruction is independent of both EWEN and EWDS instructions. The PE is internally pulled up to VCC. If the PE is left unconnected, the part will accept WRITE, EWEN and EWDS instructions. x Busy/Ready status signal After a write instruction, the DO output serves as a Busy/Ready status indicator. After the falling edge of the CS initiates the self-timed programming cycle, the DO indicates the Busy/Ready status of the chip if the CS is brought high after a minimum of 250ns Tcs . DO=logical "0" indicates that programming is still in progress. DO=logical "1" indicates that the register at the address specified in the instruction has been written with the new data pattern contained in the instruction and the part is ready for a next instruction. The Busy/Ready status indicator is only valid when CS is active high . When CS is low, the DO output goes into a high impedance state. The Busy/Ready signal outputs until a start bit Logic"1" of the next instruction is given to the part. - Type of Products Model AK93C45AF AK93C45AV AK93C55AF AK93C55AV AK93C65AF AK93C65AV AK93C75AV Memory size 1K bits 2K bits 4K bits 8K bits Temp.
