Output float is defined as the point when data is no longer driven.
Address to Output Delay. Voltage on Any Pin with Respect to Ground This capacitor should be positioned as.
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. Additionally, to stabilize the supply voltage level on printed circuit boards with large EPROM arrays, a 4. Typical values for nominal supply voltage. Integrated Product Identification Code.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Commercial and Industrial Temperature Ranges. Atmel’s scaled CMOS technology provides low active power consumption, and fast program- ming.
This capacitor should be connected between the V. At a minimum, a 0. Refer to Programming Characteristics 3.
Search datasueet Part name Part description. Input Test Waveforms and Measurement Levels. The AT27C requires only one 5V power supply in normal read mode operation. Two identifier bytes may be selected.

OE may be delayed up to t. Timing measurement references are 0. Input AC drive levels are 0. All Ai inputs are held low V. Switching between active and standby conditions via the Chip Enable pin may produce tran- sient voltage excursions. The Rapid Programming Algorithm reduces the time required to program the part and guaran- tees reliable programming. Voltage on A9 with Respect to Ground Programming datwsheet is typically only Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent dam- age to the device.
Unless accommodated by the system design, these transients may exceed datasheet limits, resulting in device non-conformance. F bulk electrolytic capacitor should be utilized, again. Power consumption is typically 8 mA in active mode and less than 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. AC Waveforms for Read Operation. CE to Output Delay. The device features two-line control CE, OE to eliminate bus contention in high-speed systems. The supply current would then be the sum of I. This feature is used by industry standard programming equipment to select the proper programming algo- rithms and voltages.
