Description (Continued)  
System Considerations  
The AT27C040 is available in a choice of industry stand-  
ard 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.  
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  
Atmel’s AT27C040 has additional features to ensure high  
quality and efficient production use. The Rapid Program-  
ming Algorithm reduces the time required to program the  
part and guarantees reliable programming. Programming  
time is typically only 100 µs/byte. The Integrated Product  
Identification Code electronically identifies the device and  
manufacturer. This feature is used by industry standard  
programming equipment to select the proper program-  
ming algorithms and voltages.

the device, as close to the device as possible. Additionally,  
to stabilize the supply voltage level on printed circuit  
boards with large EPROM arrays, a 4.7 µF bulk electrolytic  
capacitor should be utilized, again connected between the  
V
and Ground terminals. This capacitor should be posi-
