A27020 Series Functional Description Read Mode The A27020 has two control functions, both of which must be logically active in order to obtain data at the outputs. CE is the power control and should be used for device selection. OE is the output control and should be used to data to the output pins, which is independent of device selection. Assuming that addresses are stable, address access time (tAA) is equal to the delay from CE to output (tCE). Data is available at the output after a delay (tOE) from the falling edge of OE , as long as CE has been low and the addresses have been stable for at least tACC - tOE. Standby Mode The A27020 has a standby mode which reduces the active current from 30mA to 100µA. The A27020 is placed in the standby mode by applying a CMOS high signal to CE . When in the standby mode, the output are in a high impedance state, independent of the OE . The auto identify mode allows the reading out of a binary code from a EPROM that will identify its manufacturer and type. This mode is intended for use by programming equipment for the purpose of automatically matching the device to be programmed with its corresponding programming algorithm. To activate the mode, the programming equipment must apply 12.0V ± 0.5V
