512K, x16 EPROM

The AT27C516 is a low-power, high-performance 524,288-bit one-time programmable read-only memory (OTP EPROM) organized 32K by 16 bits. It requires only one 5V power supply in normal read mode operation. Any word can be accessed in less than 45 ns, eliminating the need for speed reducing WAIT states. The by-16 organization make this part ideal for high-performance 16- and 32-bit microprocessor systems.In read mode, the AT27C516 typically consumes 15 mA. Standby mode supply current is typically less than 10 μA.

The AT27C516 is available in industry-standard JEDEC-approved one-time programmable (OTP) plastic PLCC and VSOP packages. The device features two-line control (CE, OE) to eliminate bus contention in high-speed systems. With 32K word storage capability, the AT27C516 allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. Atmel’s AT27C516 have additional features to ensure high quality and efficient production use. The Rapid Programming 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.
