SM0805-E-601R Suppliers 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 offData Polling: The AT89C2051 features Data Polling toindicate the end of a write cycle. During a write cycle, anattempted read of the last byte written will result in the com-plement of the written data on Pl.7. Once the write cyclehas been completed, true data is valid on all outputs, andthe next cycle may begin. Data Polling may begin any timeafter a write cycle has been initiated.

This kind of loading istypical of multipoint buses where cards are attached at1in or 0.8in intervals along the length of a backplane. SM0805-E-601R Pdf This is especially true for devices in which the surface (back), or side of the chip is exposed. When designingcircuits, make sure that devices are protected against incident light from external sources. Exposure to light bothduring regular operation and during inspection must be taken into account. |
