and software handshaking with Ready/Busy, Data

Polling and Toggle Bit. The M28C17 supports 64

byte page write operation. A Software Data Protec-

tion (SDP) is also possible using the standard

JEDEC algorithm.

PIN DESCRIPTION

Addresses (A0-A10). The address inputs select

an 8-bit memory location during a read or write

operation.

Chip Enable (E). The chip enable input must be

low to enable all read/write operations. When Chip

Enable is high, power consumption is reduced.

Output Enable (G). The Output Enable input con-

trols the data output buffers and is used to initiate

read operations.

Data In/ Out (DQ0 - DQ7). Data is written to or read

from the M28C17 through the I/O pins.

Write Enable (W). The Write Enable input controls

the writing of data to the M28C17.

Ready/Busy (RB). Ready/Busy is an open drain

output that can be used to detect the end of the

internal write cycle.
