Reading dataout of the device is similar to reading from other Flash or EPROM devices. organized as 131,072 bytes of 8 bits each. The 128 Kbytes of data are further divided into four sectors for flexible Device programming occurs yb writing the proper program command sequence. This initiates the Embedded Program sector erase capability. The 8 bits of data appear on I/O0 - I/ O7 while the addresses are input on A0 to A16. The algorithm - an internal algorithm that automatically times the AS29CF010-55CCIN is offered in 32-pin PLCC packages. program pulse widths and verifies proper program margin.

Besides the I/O6 operation is complete by reading the I/O7 (Data Polling) and toggle bit, the AS29CF010-55CCIN has a second toggle bit, I/O6 (toggle) status bits.
