The AT27C040 requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 70 ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems. Atmel's scaled CMOS technology provides low active power consumption, and fast programming. Power consumption is typically 8 mA in active mode and less than 10 µA in standby mode. continued Pin Configurations Pin Name Function PDIP, SOIC Top View A0 - A18 Addresses O0 - O7 Outputs Chip Enable Output Enable 4-Megabit 512K x 8 OTP EPROM AT27C040 PLCC Top View TSOP Top View The AT27C040 is available in a choice of industry standard JEDEC-approved one-time programmable OTP plastic PDIP, PLCC, SOIC SOP , and TSOP packages.

Unless accommodated by the system design, these transients may exceed data sheet limits, resulting in device non-conformance. At a minimum, a µF high frequency, low inherent inductance, ceramic capacitor should be utilized for each device. This capacitor should be connected between the VCC and Ground terminals of the device, as close to the device as possible. Additionally, to stabilize the supply voltage level on printed circuit boards with large EPROM arrays, a µF bulk electrolytic capacitor should be utilized, again connected between the VCC and Ground terminals. This capacitor should be positioned as close as possible to the point where the power supply is connected to the array.
