OE may be delayed up to t. Two identifier bytes may be selected. Voltage on Any Pin with Respect to Ground The Rapid Programming Algorithm reduces the time required to program the part and 27c400 tees reliable programming.
This capacitor should be connected between the V.
Typical values for nominal supply voltage. The device features two-line control CE, OE to eliminate bus contention in high-speed systems. The AT27C requires only one 5V power supply in normal read mode operation.
OE to Output Delay. Input AC drive levels are 0. Programming time is datwsheet only Output float is defined as the point when data is no longer driven. The supply current would then be the sum of I.
At a minimum, a 0. CE to Output Delay. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Atmel’s AT27C has additional features to ensure high quality and efficient production use.
Any byte can be accessed in less than 70 ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems.

F bulk electrolytic capacitor should be utilized, again. Atmel’s scaled CMOS technology provides low active 27c400 consumption, and fast program- ming. AC Characteristics for Read Operation.
Power consumption datashewt typically 8 mA in active mode and less than Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent dam- age to the device.
Product Identification Code electronically identifies the device and manufacturer.
This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. All Ai inputs are held low V. Address to Output Delay.
