Product Overview

The AT27C020-90JU is a low-power high-performance 2097152-bit One-Time Programmable Read-Only Memory (OTP EPROM) organized as 256K by 8-bit. It requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 90ns, eliminating the need for speed-reducing WAIT states on high-performance microprocessor systems. In read mode, the AT27C020 typically consumes 8mA. Standby mode supply current is typically less than 10µA. The device features 2-line control (CE, OE) to give designers the flexibility to prevent bus contention. With 256K byte storage capability, the AT27C020 allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. The AT27C020 has 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 100µs/byte.
