The AT27C516 is a low-power, high performance 524,288 bit one-time programma-ble read only memory (OTP EPROM) organized 32K by 16 bits. It requires only one5V power supply in normal read mode operation. Any word can beaccessed in lessthan 45 ns, eliminating the need for speed reducing WAIT states. The by-16 organi-zation make this part ideal for high-performance 16 and 32 bit microprocessor sys-tems
In read mode, the AT27C516 typically consumes 15 mA.Standby mode supply current is typically less than 10 A.
The AT27C516 is available in industry standardJEDEC-approved one-time programmable (OTP) plasticPLCC and TSOP packages. The device features two-linecontrol (CE, OE) to eliminate bus contention in high-speedsystems.
With 32K word storage capability, the AT27C516 allowsfirmware to be stored reliably and to be accessed by thesystem without the delays of mass storage media.
Atmel's 27C516 have additional features to ensure high(TM)quality and efficient production use. The Rapid Programming Algorithm reduces the time required to program thepart and guarantees reliable programming. Programmingtime is typically only 50 s/word. The Integrated ProductIdentification Code electronically identifies the device and manufacturer. This feature is used by industry standardprogramming equipment to select the proper program-ming algorithms and voltages.
