General Description
The A23L9308 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 2.7V to 3.6V.

524,288 X 8 BIT CMOS MASK ROM
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.
The A23L9308 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. A23L9308
also offers OE/ OE /NC (Active High or Low or No
Connection), which eliminates bus contention in multiple
bus microprocessor systems.
