... EPROMs. The X28C010 supports a 256-byte page write operation, effectively providing a 19 s/byte write cycle and en- abling the entire memory to be typically written in less than 2.5 seconds. The X28C010 also features DATA Polling and Toggle Bit Polling, system software support schemes used to indicate the early completion of a write cycle ...

... X28C010 PIN DESCRIPTIONS Addresses (A – The Address inputs select an 8-bit memory location during a read or write operation. Chip Enable (CE) The Chip Enable input must be LOW to enable all read/ write operations. When CE is HIGH, power consumption is reduced. Output Enable (OE) The Output Enable input controls the data output buffers and is used to initiate read operations ...

... Page Write Operation The page write feature of the X28C010 allows the entire memory to be written in 5 seconds. Page write allows two to two hundred fifty-six bytes of data to be consecu- tively written to the X28C010 prior to the commence- ment of the internal programming cycle. The host can ...
