4 / 15 page M27W102 4/15 DEVICE OPERATION The operating modes of the M27W102 are listed in the Operating Modes table. A single power supply is required in the read mode. All inputs are TTL levels except for VPP and 12V on A9 for Electronic Signature. Read Mode The M27W102 has two control functions, both of which must be logically active in order to obtain data at the outputs. Chip Enable (E) is the power control and should be used for device selection. Output Enable (G) is the output control and should be used to gate data to the output pins, indepen- dent of device selection. Assuming that the ad- dresses are stable, the address access time (tAVQV) is equal to the delay from E to output (tELQV). Data is available at the output after a delay of tOE from the falling edge of G, assuming that E has been low and the addresses have been stable for at least tAVQV-tGLQV. Standby Mode The M27W102 has a standby mode which reduc- es the supply current from 15mA to 15 µA with low voltage operation VCC ≤ 3.6V, see Read Mode DC Characteristics table for details. The M27W102 is placed in the standby mode by applying a CMOS high signal to the E input. When in the standby mode, the outputs are in a high impedance state, independent of the G input. Table 5.
