Description  
The Atmel® AT27C020 is a low-power, high-performance, 2,097,152-bit, one-time pro-  
grammable, read-only memory (OTP EPROM) organized as 256K by 8 bits. It requires only  
one 5V power supply in normal read mode operation. Any byte can be accessed in less than  
55ns, eliminating the need for speed-reducing WAIT states on high-performance micropro-  
cessor systems.  
In read mode, the AT27C020 typically consumes 8mA. Standby mode supply current is  
typically less than 10µA.  
The AT27C020 is available in a choice of industry-standard, JEDEC approved, one-time pro-  
grammable (OTP) PDIP and PLCC packages. All devices feature two-line control (CE, OE)  
to give designers the flexibility to prevent bus contention.  
With 256K byte storage capability, the AT27C020 allows firmware to be stored reliably and  
to be accessed by the system without the delays of mass storage media.  
The AT27C020 has additional features to ensure high quality and efficient production use.  
The rapidprogramming algorithm reduces the time required to program the part and guar-  
antees reliable programming. Programming time is typically only 100µs/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 pro-  
gramming algorithms and voltages.
