Description  
The Atmel AT27C4096 is a low-power, high-performance, 4,194,304-bit, one-time pro-  
grammable, read-only memory (OTP EPROM) organized as 256K by 16 bits. It requires a  
single 5V power supply in normal read mode operation. Any word can be accessed in less  
than 55ns, eliminating the need for speed reducing WAIT states. The x16 organization  
makes this part ideal for high-performance, 16- and 32-bit microprocessor systems.  
In read mode, the AT27C4096 typically consumes 15mA. Standby mode supply current is  
typically less than 10µA  
The AT27C4096 is available in industry-standard, JEDEC-approved, one-time programma-  
ble (OTP) PDIP and PLCC packages. The device features two-line control (CE, OE) to  
eliminate bus contention in high speed systems.  
With high-density 256K word storage capability, the AT27C4096 allows firmware to be  
stored reliably and to be accessed by the system without the delays of mass storage media.  
The AT27C4096 has additional features that ensure high quality and efficient production  
use. The rapidprogramming algorithm reduces the time required to program the part and  
guarantees reliable programming. Programming time is typically only 50µs/word. The Inte-  
grated 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.
