Description	512K 64K x 8 Multiplexed Addresses/ Outputs OTP EPROM
Datasheet	AT27C520_ATMELCorporation.pdf

The AT27C520 is a low-power, high performance 524,288 bit one-time programmable read only memory (OTP EPROM) organized 64K by 8 bits.

It incorporates latches for the 8 lower order address bits to multiplex with the 8 data bits.

This minimizes system chip count, reduces cost, and simplifies the design of multiplexed bus systems.

8-Bit Multiplexed Addresses/Outputs.
