System Considerations  
Description (Continued)  
Standby mode supply current is typically less than 1 µA at  
3V. The AT27BV512 simplifies system design and  
stretches battery lifetime even further by eliminating the  
need for power supply regulation.  
Switching between active and standby conditions via the  
Chip Enable pin may produce transient voltage excur-  
sions. Unless accommodated by the system design, these  
transients may exceed data sheet limits, resulting in de-  
vice non-conformance. At a minimum, a 0.1 µF high fre-  
quency, low inherent inductance, ceramic capacitor  
should be utilized for each device. This capacitor should  
The AT27BV512 is available in industry standard JEDEC-  
approved one-time programmable (OTP) plastic PLCC,  
SOIC, and TSOP packages. All devices feature two-line  
control (CE, OE) to give designers the flexibility to prevent  
bus contention.

to stabilize the supply voltage level on printed circuit  
boards with large EPROM arrays, a 4.7 µF bulk electrolytic

tioned as close as possible to the point where the power  
supply is connected to the array.  
Atmel’s AT27BV512 has additional features to ensure  
high quality and efficient production use. The Rapid Pro-  
gramming Algorithm reduces the time required to program  
the part and guarantees reliable programming. Program-  
ming time is typically only 100 µs/byte. The Integrated  
Product Identification Code electronically identifies the de-  
vice and manufacturer. This feature is used by industry  
standard programming equipment to select the proper  
programming algorithms and voltages. The AT27BV512  
programs exactly the same way as a standard 5V  
AT27C512R and uses the same programming equipment.
