AT27C512R  
1. Description  
The AT27C512R is a low-power, high-performance 524,288-bit one-time programma-  
ble read-only memory (OTP EPROM) organized 64K by 8 bits. It requires only one 5V  
power supply in normal read mode operation. Any byte can be accessed in less than  
45 ns, eliminating the need for speed reducing WAIT states on high-performance  
microprocessor systems.  
Atmel’s scaled CMOS technology provides high-speed, lower active power consump-  
tion, and significantly faster programming. Power consumption is typically only 8 mA  
in Active Mode and less than 10 µA in Standby.  
The AT27C512R is available in a choice of industry-standard JEDEC-approved one-  
time programmable (OTP) plastic PDIP, PLCC, SOIC, and TSOP packages. All  
devices feature two-line control (CE, OE) to give designers the flexibility to prevent  
bus contention.  
With 64K byte storage capability, the AT27C512R allows firmware to be stored reli-  
ably and to be accessed by the system without the delays of mass storage media.  
Atmel’s AT27C512R has additional features to ensure high quality and efficient pro-  
duction use. The Rapid Programming 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 programming algorithms and voltages.
