AT27C2048  
1. Description  
The AT27C2048 is a low-power, high-performance 2,097,152-bit one-time program-  
mable read-only memory (OTP EPROM) organized 128K by 16 bits. It requires a  
single 5V power supply in normal read mode operation. Any word can be accessed in  
less than 55 ns, eliminating the need for speed-reducing WAIT states. The by-16  
organization makes this part ideal for high-performance 16 and 32 bit microprocessor  
systems.  
In read mode, the AT27C2048 typically consumes 15 mA. Standby mode supply cur-  
rent is typically less than 10 µA.  
The AT27C2048 is available in industry-standard JEDEC-approved one-time pro-  
grammable (OTP) plastic PDIP, PLCC, and VSOP packages. The device features  
two-line control (CE, OE) to eliminate bus contention in high-speed systems.  
With high density 128K word storage capability, the AT27C2048 allows firmware to be  
stored reliably and to be accessed by the system without the delays of mass storage  
media.  
Atmel’s AT27C2048 has additional features that ensure high quality and efficient pro-  
duction use. The RapidProgramming Algorithm reduces the time required to program  
the part and guarantees reliable programming. Programming time is typically only  
50 µs/word. 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 algorithms and voltages.
