... Read The AT28HC64B is accessed like a Static RAM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the out- puts. The outputs are put in the high-impedance state when either high. This dual line control gives designers flexibility in preventing bus contention in their systems. ...

... A software-controlled data protection feature has been implemented on the AT28HC64B. When enabled, the software data protection (SDP), will prevent inadvertent writes. The SDP feature may be enabled or disabled by the user; the AT28HC64B is shipped from Atmel with SDP disabled. SDP is enabled by the user issuing a series of three write commands in which three specific bytes of data are written to three specific addresses (refer to the “ ...
