... The AT27C040 chip is a low-power, high-performance, 4,194,304-bit one-time pro- grammable read only memory (OTP EPROM) organized as 512K by 8 bits. The AT27C040 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 ...

... The AT27C040 is available in a choice of industry standard JEDEC-approved one-time programmable (OTP) plastic PDIP, PLCC, SOIC (SOP), and TSOP packages. The device features two-line control (CE, OE) to eliminate bus contention in high-speed systems. Atmel's AT27C040 has additional features to ensure high quality and efficient production use. The Rapid ming Algorithm reduces the time required to program the part and guarantees reliable programming ...

In the event a byte fails to pass verification succes- sive 100 s pulses are applied with a verification after each AT27C040 8 pulse. If the byte fails to verify after 10 pulses have been is applied, the part is considered failed. After the byte verifies ...
