Description
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. It
requires only one 5V power supply in normal read mode operation. Any byte can be
accessed in less than 70 ns, eliminating the need for speed reducing WAIT states on
high performance microprocessor systems.
Atmel’s scaled CMOS technology provides high speed, lower active power consump-
tion, and significantly faster programming. Power consumption is typically only 8 mA
in Active Mode.
The AT27C520 is available in 173 mil, 20-pin TSSOP; 300 mil, 20-pin SOIC; and 28-
pin TSOP, one-time programmable (OTP) plastic packages.
