Atmel’s scaled CMOS technology provides low active power consumption, and fast program-  
ming. Power consumption is typically 8 mA in active mode and less than 10 µA in standby  
mode.  
The AT27C040 is available in a choice of industry standard JEDEC-approved one-time pro-  
grammable (OTP) plastic PDIP, PLCC 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 Programming Algorithm reduces the time required to program the part and guaran-  
tees 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 programming algo-  
rithms and voltages.  
Switching  
Considerations  
Switching between active and standby conditions via the Chip Enable pin may produce tran-  
sient voltage excursions. Unless accommodated by the system design, these transients may  
exceed datasheet limits, resulting in device non-conformance. At a minimum, a 0.1 µF high  
frequency, low inherent inductance, ceramic capacitor should be utilized for each device. This  
capacitor should be connected between the VCC and Ground terminals of 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 VCC and Ground terminals. This capacitor should be positioned as  
close as possible to the point where the power supply is connected to the array.
