A23W9308 Preliminary Features n n n n n 524,288 x 8 bit organization Wide power supply range : +2.7V to +5.5V Access time: 120 ns (max.)/5V 150 ns (max.)/3V Current: Operating: 50mA (max.)/5V 15mA (max.)/3V Standby: 50A (max.)/5V 25A (max.)/3V n Mask Programmed for Chip Enable (power-down) CE/ CE , Output Enable OE/ OE /NC n Three-state outputs for wired-OR expansion n Full static operation n All inputs and outputs are directly TTL-compatible n Available in 32-pin DIP, 32-pin SOP, 32-pin PLCC packages or in DICE FORM. 524,288 X 8 BIT CMOS MASK ROM General Description The A23W9308 high-performance Read Only Memory is configured as 524,288 x 8 bits. It is designed to be compatible with all microprocessors and similar applications where high-performance, large-bit storage, and simple interfacing are important design considerations. This device is designed for use with operating voltage from 3V to 5V. The A23W9308 offers an automatic POWER-DOWN controlled by the Chip Enable CE/ CE input. When CE/ CE goes low/high, the device will automatically POWER-DOWN and remain in a low power STANDBY mode as long as CE/ CE remains low/high. A23W9308 also offers OE/ OE /NC (Active High or Low or No Connection), which eliminates bus contention in multiple bus microprocessor systems.
