Voltage on Any Pin with Respect to Ground Timing measurement references are 0.
Voltage on A9 with Respect to Ground Integrated Product Identification Code. AC Characteristics for Read Operation. Switching between active and standby conditions via the Chip Enable pin may produce tran- sient voltage excursions. Commercial and Industrial Temperature Dataaheet. Output float datashet defined as the point when data is no longer driven. Additionally, to stabilize the supply voltage level on printed circuit boards with large EPROM arrays, a 4. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
The supply current would then be the sum of I. Typical values for nominal supply voltage. The device features two-line control CE, OE to eliminate bus contention in high-speed systems. All Ai inputs are held low V.
Atmel’s scaled CMOS technology provides low active power consumption, datwsheet fast program- ming. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent dam- age to the device. This capacitor should be connected between the V. This capacitor should be positioned as.
This feature is used by industry standard programming equipment to select the proper programming algo- rithms and voltages. Address to Output Delay.
OE to Output Delay. The AT27C requires only one 5V power supply in normal read mode operation. Refer to Programming Characteristics 3. Atmel’s AT27C has additional features to ensure high quality and efficient production use.
The Rapid Programming Algorithm reduces the time required to program the part and guaran- tees reliable programming.

F bulk electrolytic capacitor should be utilized, again. Input AC drive levels are 0. 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.
CE to Output Delay. Power consumption is typically 8 mA in active mode and less than Product Identification Code electronically identifies the device and manufacturer. AC Waveforms for Read Operation.
Search field Part name Part description. Input Test Waveforms and Measurement Levels. Programming time is typically only Unless accommodated by the system design, these transients may exceed datasheet limits, resulting in device non-conformance.
Any byte can be accessed in less datashewt 70 ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems. At a minimum, a 0.
Two identifier bytes may be selected. OE may be delayed up to t.
