Product Summary
The AT28C256E-20TI is accessed like a Static RAM for the reador write cycle without the need for external components.The device contains a 64-byte page register to allow writ-ing of up to 64-bytes simultaneously. During a write cycle,the addresses and 1 to 64-bytes of data are internallylatched, freeing the address and data bus for other opera-tions. Following the initiation of a write cycle, the AT28C256E-20TI will automatically write the latched data using an internalcontrol timer. The end of a write cycle can be detected byDATA POLLING of I/O7. Once the end of a write cycle hasbeen detected a new access for a read or write can begin
