MX93000CKC-46C Datasheet
MX93000CKC-46C Price Device operations are selected by writing specific address and data sequences into the command register. The following table defines these register command sequences for 8 bit mode. For 16 and 32 bit mode, the data values in the table should be repeated on each byte of the data bus, when entering a command sequence. Data to be stored should be entered normally as 16 0r 32 bit.

6. Pulse P3.2 0nce to program a byte in the PEROM array or the lock bits. The byte-write cycle is self-timed and typically takes l.2 ms. 7. To verify the programmed data, lower RST from 12V to logic 'H'Ievel and set pins P3.3 to P3.7 to the appropiate levels. Output data can be read at the port Pl pins. 8. To program a byte at the next address location, pulse XTALl pin once to advance the internal address counter. Apply new data to the port Pl pins. 9. Repeat steps 5 through 8, changing data and advancing the address counter for the entire 2K bytes array or until the end of the object file is reached. 10.Power-off sequence: set XTALl to 'L' set RST to 'L' Turn Vcc power off Data Polling: The AT89C2051 features Data Polling to indicate the end of a write cycle. During a write cycle, an attempted read of the last byte written will result in the com- plement of the written data on Pl.7. Once the write cycle has been completed, true data is valid on all outputs, and the next cycle may begin. Data Polling may begin any time after a write cycle has been initiated. |
