... Any byte can be accessed in less than 55 ns, eliminating the need for speed reducing WAIT states on high perfor- mance microprocessor systems. In read mode, the AT27C020 typically consumes 8 mA. Standby mode supply current is typically less than 10 A. Pin Configurations ...

... The AT27C020 is available in a choice of industry standard JEDEC-approved one-time programmable (OTP) plastic PDIP, PLCC, and TSOP packages. All devices feature two- line control (CE, OE) to give designers the flexibility to pre- vent 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. Atmel’ ...
